The Decade Volcanoes are 16 volcanoes identified by the International Association of Volcanology and Chemistry of the Earth's Interior (IAVCEI) as being worthy of particular study in light of their history of large, destructive eruptions and proximity to densely populated areas. The Decade Volcanoes project encourages studies and public-awareness activities at these volcanoes, with the aim of achieving a better understanding of the volcanoes and the dangers they present, and thus being able to reduce the severity of natural disasters .

139-603: They are named Decade Volcanoes because the project was initiated in the 1990s as part of the United Nations –sponsored International Decade for Natural Disaster Reduction . A volcano may be designated a Decade Volcano if it exhibits more than one volcanic hazard (people living near the Decade Volcanoes may experience tephra fall, pyroclastic flows , lava flows , lahars , volcanic edifice instability and lava dome collapse); shows recent geological activity;

278-674: A "systemic failure". In 2010, the organization suffered the worst loss of life in its history, when 101 personnel died in the Haiti earthquake . Acting under the United Nations Security Council Resolution 1973 in 2011, NATO countries intervened in the First Libyan Civil War . The Millennium Summit was held in 2000 to discuss the UN's role in the 21st century. The three-day meeting was

On 7 November 1956, the first UN peacekeeping force was established to end the Suez Crisis ; however, the UN was unable to intervene against the Soviet Union's simultaneous invasion of Hungary , following the country's revolution . On 14 July 1960,

556-574: A distance of 2.5 km (1.6 mi) east of the lava dome on May 26, and 3 km (1.9 mi) on May 29. On May 26 when the tip of a pyroclastic flow approached 500 m (1,600 ft) from the nearest private houses, Shimabara City issued an evacuation recommendation for Kita-Kamikoba town, Minami-Kamikoba town, Shirataki town, Tenjin Motomachi, and Fudan Motomachi – all located in the Mizunashi River basin. The evacuation recommendation

695-595: A filming location of the press. From May 15, when the debris flow evacuation advisory was issued, the fire brigade in charge of the Kamikoba district stayed either at the Minami-Kamikoba town fire brigade, or the Kita-Kamikoba town agricultural training center (which was initially an evacuation residence for locals). On May 29, due to the frequent occurrences of pyroclastic flows, they were evacuated from

834-1013: A myriad of autonomous, separately administered funds, programmes, research and training institutes, and other subsidiary bodies . Each of these entities have their own area of work, governance structure, and budgets such as the World Trade Organization (or the WTO) and the International Atomic Energy Agency (or the IAEA), operate independently of the UN but maintain formal partnership agreements. The UN performs much of its humanitarian work through these institutions, such as preventing famine and malnutrition (the World Food Programme ), protecting vulnerable and displaced people (the UNHCR ), and combating

973-504: A new law in the vicinity of Mount Rainier , requiring assessment of geological hazards before any new developments; limitations on high density housing developments in the Taal Caldera; and the development of an evacuation plan for parts of Naples which might be affected in the event of an eruption at Vesuvius . Although studies at many Decade Volcanoes have clearly reduced the risks faced by nearby settlements, eruptions at some of

1112-426: A peach, eventually splitting and collapsing into four pieces under its own weight. After that, the dome continued to grow, continuously supplied with fresh lava from the crater underneath, creating new lobes that hung down from the summit. The 1st to 13th lobes were named in the order they were formed. Collapsing of the lava dome began to occur when the lobes, pushed out by the newly supplied magma, started to give way on

1251-547: A permanent member to block adoption of a resolution, though not debate. The ten temporary seats are held for two-year terms, with five members elected each year by the General Assembly on a regional basis . The presidency of the Security Council rotates alphabetically each month. The UN Secretariat carries out the day-to-day duties required to operate and maintain the UN system. It is composed of tens of thousands of international civil servants worldwide and headed by

1390-606: A plane crash . Months later he was posthumously awarded the Nobel Peace Prize . In 1964, Hammarskjöld's successor, U Thant , deployed the UN Peacekeeping Force in Cyprus , which would become one of the UN's longest-running peacekeeping missions. With the spread of decolonization in the 1960s, the UN's membership shot up due to an influx of newly independent nations. In 1960 alone, 17 new states joined

1529-545: A point in Fukae Town outside the evacuation zone on May 28, and switched to 24-hour shooting from there. At the "fixed point", the coverage in the vicinity was limited to patrols. Similarly, the Japan Broadcasting Corporation (NHK) stopped shooting from within the evacuated area from the end of May and arranged for an unmanned camera in the Kamikoba area. But until the unmanned camera was ready,

1668-504: A result of those two factors, most residents were withdrawn from the evacuation advisory area, and fortunately resulted in fewer victims. The eruption activity continued until March 1995, with a temporary pause during its course. Between 1991 and 1994, the volcano generated at least 10,000 small pyroclastic flows, destroying about 2,000 houses. From 1993 onward, the rate of lava effusion gradually decreased, and eruptions came to an end in 1995. The 1990–1995 eruptions of Unzen were

1807-557: A seismic intensity of 5 occurred in August near the south side of Hayama. As a result of this earthquake, uplift of the Shimabara Peninsula was observed, and magma supply from Tachibana Bay began. In November 1989, an earthquake swarm began about 20 km (12 mi) underneath and 10 km (6.2 mi) west of Fugen-dake. Over the following year, earthquakes continued, and their hypocentres gradually migrated towards

1946-445: A two-thirds majority of those present and voting is required. All other questions are decided by a majority vote. Each member has one vote. Apart from the approval of budgetary matters, resolutions are not binding on the members. The Assembly may make recommendations on any matters within the scope of the UN, except matters of peace and security that are under consideration by the Security Council. Draft resolutions can be forwarded to

2085-467: A while, before succumbing later to their injuries (burns to their skin and lungs, or inhaled ash in their windpipe and lungs). The final victim reportedly died on August 8. The collapse of the lava dome itself left a notable scar on the eastern side of the summit, and the pyroclastic flow and surge resulted in much damage in the Kamikoba district. Kita-Kamikoba was almost completely destroyed. Around 170 houses were devastated, many of them set alight by

2224-889: A wide variety of complex tasks. The UN comprises six principal operational organizations: the General Assembly , the Security Council , the Economic and Social Council , the International Court of Justice , the UN Secretariat , and the Trusteeship Council , although the Trusteeship Council has been suspended since 1994. The UN System includes a multitude of specialized agencies , funds, and programmes, including

2363-1033: A wide variety of topics. These include the United Nations Permanent Forum on Indigenous Issues , which advises UN agencies on issues relating to indigenous peoples , the United Nations Forum on Forests , which coordinates and promotes sustainable forest management, the United Nations Statistical Commission , which co-ordinates information-gathering efforts between agencies, and the Commission on Sustainable Development , which co-ordinates efforts between UN agencies and NGOs working towards sustainable development . ECOSOC may also grant consultative status to non-governmental organizations. as of April 2021 almost 5,600 organizations have this status. The UN Charter stipulates that each primary organ of

2502-467: Is defined in the UN Charter as the organization's chief administrative officer. Article 99 of the charter states that the secretary-general can bring to the Security Council's attention "any matter which in their opinion may threaten the maintenance of international peace and security", a phrase that secretaries-general since Trygve Lie have interpreted as giving the position broad scope for action on

2641-401: Is located in a densely populated area (eruptions at any of the Decade Volcanoes may threaten tens or hundreds of thousands of people, and therefore mitigating eruption hazards at these volcanoes is crucial); is politically and physically accessible for study; and there is local support for the work. The general approach of Decade Volcano projects has been to convene a planning workshop, identify

2780-568: Is not allowable under most national or bilateral funding—is the exchange of scientists and civil defence leaders between the various Decade Volcano projects of developing countries, for example, between the Philippines and Indonesia, or between Mexico, Guatemala, and Colombia, or across the Pacific and Atlantic. Often, scientists and civil defence leaders from developing countries can relate better to each other's experiences than they can to

3058-655: The Battle of Mogadishu . The UN mission to Bosnia faced worldwide ridicule for its indecisive and confused mission in the face of ethnic cleansing. In 1994, the UN Assistance Mission for Rwanda failed to intervene in the Rwandan genocide amidst indecision in the Security Council. From the late 1990s to the early 2000s, international interventions authorized by the UN took a wider variety of forms. The United Nations Security Council Resolution 1244 authorised

3197-528: The Four Power Declaration on General Security which aimed for the creation "at the earliest possible date of a general international organization". This was the first public announcement that a new international organization was being contemplated to replace the League of Nations. The Tehran Conference followed shortly afterwards at which Roosevelt, Churchill and Joseph Stalin , the leader of

3336-540: The Group of 77 under the leadership of Algeria, which briefly became a dominant power at the UN. On 10 November 1975, a bloc comprising the Soviet Union and Third World nations passed a resolution , over strenuous American and Israeli opposition, declaring Zionism to be a form of racism . The resolution was repealed on 16 December 1991, shortly after the end of the Cold War. With an increasing Third World presence and

The invasion of Afghanistan in 2001 was overseen by NATO. In 2003, the United States invaded Iraq despite failing to pass a UN Security Council resolution for authorization, prompting a new round of questioning of the UN's effectiveness. Under

3753-820: The Paris Peace Conference . The League of Nations was approved and started operations, but the United States never joined. On 10 January 1920, the League of Nations formally came into being when the Covenant of the League of Nations , ratified by 42 nations in 1919, took effect. The League Council acted as an executive body directing the Assembly's business. It began with four permanent members—the United Kingdom , France , Italy , and Japan . After some limited successes and failures during

Additionally, non-governmental organizations may be granted consultative status with the Economic and Social Council and other agencies. The UN's chief administrative officer is the secretary-general , currently António Guterres , who is a Portuguese politician and diplomat. He began his first five-year term on 1 January 2017 and

4170-800: The aim of preventing future world wars , and succeeded the League of Nations , which was characterized as being ineffective. On 25 April 1945, 50 nations assembled in San Francisco , California, for a conference and initialised the drafting of the UN Charter , which was adopted on 25 June 1945. The charter took effect on 24 October 1945, when the UN began operations. The UN's objectives, as outlined by its charter, include maintaining international peace and security, protecting human rights , delivering humanitarian aid , promoting sustainable development , and upholding international law . At its founding,

4309-406: The secretary-general , who is assisted by the deputy secretary-general . The Secretariat's duties include providing information and facilities needed by UN bodies for their meetings and carrying out tasks as directed by the Security Council, the General Assembly, the Economic and Social Council, and other UN bodies. The secretary-general acts as the spokesperson and leader of the UN. The position

4726-702: The 1920s, the League proved ineffective in the 1930s, as it failed to act against the Japanese invasion of Manchuria in 1933. Forty nations voted for Japan to withdraw from Manchuria but Japan voted against it and walked out of the League instead of withdrawing from Manchuria. It also failed to act against the Second Italo-Ethiopian War , after the appeal for international intervention by Ethiopian Emperor Haile Selassie I at Geneva in 1936 went with no avail, including when calls for economic sanctions against Italy failed. Italy and other nations left

4865-444: The 19th, 20th, and 21st. Shimabara City made an evacuation recommendation to the towns in the Mizunashi River basin each time, resulting in smooth evacuation of residents and no human fatalities. However, on May 20, when the lava dome appeared on Fugen-dake, it continued to grow day by day, and on May 24 part of the dome collapsed and the first pyroclastic flow occurred. After that, small pyroclastic flows occurred frequently, reaching

5004-563: The Akamatsu-dani River, but changed direction due to a gust of wind from the south, allowing the residents, firefighters, and the shooting staff (who left their camera behind to capture world-famous footage of the eruption) to immediately escape the eruption. At the "fixed point", members of the media initially left their chartered taxis and company cars on the road with their engine running, facing south so that they could escape immediately in case of an unforeseen event. However,

5143-468: The Anyoji Temple. Four of the victims' bodies were never recovered, and were reported as missing at the time, but presumed dead. Many of the recovered bodies were carbonized due to the extreme heat of the surge, and were identified by either dental records, or personal belongings they carried with them (e.g. wristwatches or cameras). Seventeen victims on the outer edges of the affected zone lived for

5282-700: The Atlantic Charter was the addition of a provision for religious freedom , which Stalin approved after Roosevelt insisted. Roosevelt's idea of the " Four Powers ", refers to the four major Allied countries, the United States, the United Kingdom, the Soviet Union, and China , emerged in the Declaration by the United Nations. On New Year's Day 1942, Roosevelt, Churchill, the Soviet Union's former Foreign Minister Maxim Litvinov , and

The first meetings of the General Assembly , with 51 nations represented, and the Security Council took place in London beginning in January 1946. Debates began at once, covering topical issues such as

5560-547: The Chijiwa Caldera. In other words, it is supplied from a magma chamber beneath Tachibana Bay off Obama Onsen. The main peak is Fugen-dake , but the volcanic activity from 1990 (Heisei 2) to 1995 (Heisei 7) made Heisei-shinzan , which was higher in elevation. Heisei-shinzan is also the highest peak in Nagasaki Prefecture. Unzen originally read "onsen" in the notation of a hot spring , but it

5838-456: The Decade Volcanoes have demonstrated the difficulties faced by the program. Eruptions at Japan's Mount Unzen which began shortly before it was designated a Decade Volcano were heavily monitored, but despite this, a large pyroclastic flow killed 43 people, including three volcanologists. Later, a 1993 Decade Volcano conference in the city of Pasto , Colombia ended in disaster when several attending scientists mounted an impromptu expedition to

Mount Unzen Mount Unzen ( 雲仙岳 , Unzen-dake ) is an active volcanic group of several overlapping stratovolcanoes , near the city of Shimabara, Nagasaki on the island of Kyushu , Japan's southernmost main island. In 1792, the collapse of one of its several lava domes triggered a megatsunami that killed 14,524 people in Japan's worst volcanic-related disaster . The volcano

6394-604: The June 3 eruption, then continued east through the Mizunashi river valley. As the pyroclastic flow reached Onokoba the pyroclastic surge detached from the main flow body as it continued moving 600 m (2,000 ft) to the SE before losing its energy and stopping. The surge was powerful enough to move a car 120 m (390 ft), flatten and uproot large trees and even move large debris in Kita-Kamikoba and Onokoba. The surge destroyed

6533-519: The Kamikoba area, in particular, there were many farmers who made a living by cultivating tobacco leaf, but since they had been forced to evacuate for a long time (since the May 15 debris flows), their work grew stagnant and many of them were concerned. For this reason, on June 4, in collaboration with tobacco farmers in Annaka Town (which had not been evacuated), the residents of the Kamikoba area entered

6672-422: The League. When war broke out in 1939 , the League effectively closed down. The first step towards the establishment of the United Nations was the Inter-Allied Conference in London that led to the Declaration of St James's Palace on 12 June 1941. By August 1941, American President Franklin Roosevelt and British Prime Minister Winston Churchill had drafted the Atlantic Charter ; which defined goals for

6811-444: The Ministry of Construction (at that time officials of the Public Works Research Institute) released a picture taken when entering the path of previous pyroclastic flows below the lava dome, and another group on the afternoon of June 1 or 2. After entering the tip of the deposit path, they surveyed the site for about an hour, photographed the pattern and released it. In addition, many visitors had begun to gather around Unzendake to see

6950-475: The Mizunashi River Valley and reaching 3.2 km (2.0 mi) to the east from the lava dome. Although the main body of the flow continued to follow the river, the resulting pyroclastic surge spread out in a fan shape once it had exited the valley mouth and continued further, hitting Kita-Kamikoba town (4 km (2.5 mi) away from the lava dome) and finally stopping near the Tsutsuno bus stop (5 km (3.1 mi) away). The pyroclastic flow also flowed down

7089-407: The Mizunashi Valley, raising the level of the river-bed and making it more likely for the flow to "skip" ridges that would have once stopped it. According to the 2011 documentary Face au Volcan Tueur (French for Facing the Killer Volcano ), the unexpected surge could have been caused by phreatic explosions as the main body of the pyroclastic flow proceeded down two waterfalls at the headwaters of

7228-434: The NE flank of the lava dome started at 16:44, with major flows following at 17:59 and 18:45 before the largest pyroclastic flow at 18:54. The first flows descended towards the NE and stopped just short of Kita-Kamikoba. The main flow initially descended on the NE flank and was then deflected by Taruki height, directing it to the SE, after which it passed through the already ravaged Kita-Kamikoba, where it remobilized debris from

7367-466: The Onokaba elementary school and burned down 150 homes. The eruptive activity caused great damage to the Shimabara Peninsula, especially Shimabara City and Fukae Town. The main factor that led to damage were debris flows and lahars, initiated by heavy rain which destabilized pyroclastic flow and ash debris previously deposited on the slopes. The Mizunashi basin, as well as the Senbongi district and parts of Shimabara were severely damaged. In addition, there

7506-427: The Soviet Union, and the signing of the Korean Armistice Agreement on 27 July 1953. On 29 November 1947, the General Assembly approved resolution 181 , a proposal to partition Palestine into two state, with Jerusalem placed under a special international regime. The plan failed and a civil war broke out in Palestine, that led to the creation of the state of Israel afterward. Two years later, Ralph Bunche ,

7645-400: The Soviet Union, before all the issues were resolved. By 1 March 1945, 21 additional states had signed the Declaration by the United Nations. After months of planning, the UN Conference on International Organization opened in San Francisco on 25 April 1945. It was attended by 50 nations' governments and a number of non-governmental organizations. The delegations of the Big Four chaired

7784-451: The Soviet Union, met and discussed the idea of a post-war international organization. The new international organisation was formulated and negotiated amongst the delegations from the Allied Big Four at the Dumbarton Oaks Conference from 21 September to 7 October 1944. They agreed on proposals for the aims, structure and functioning of the new organization. It took the conference at Yalta in February 1945, and further negotiations with

7923-499: The UN authorized a US-led coalition that repulsed Iraq's invasion of Kuwait . Brian Urquhart , the under-secretary-general of the UN from 1971 to 1985, later described the hopes raised by these successes as a "false renaissance" for the organization, given the more troubled missions that followed. Beginning in the last decades of the Cold War , critics of the UN condemned the organization for perceived mismanagement and corruption. In 1984, American President Ronald Reagan withdrew

8062-412: The UN established the United Nations Operation in the Congo (or UNOC), the largest military force of its early decades, to bring order to Katanga , restoring it to the control of the Democratic Republic of the Congo by 11 May 1964. While travelling to meet rebel leader Moise Tshombe during the conflict, Dag Hammarskjöld , often named as one of the UN's most effective secretaries-general, died in

8201-562: The UN had 51 member states ; as of 2024 , it has 193 sovereign states , nearly all of the world's recognized sovereign states. The UN's mission to preserve world peace was complicated in its initial decades due in part to Cold War tensions that existed between the United States and Soviet Union and their respective allies. Its mission has included the provision of primarily unarmed military observers and lightly armed troops charged with primarily monitoring, reporting and confidence-building roles. UN membership grew significantly following

8340-430: The UN itself and operate with almost complete independence from it". These include specialized agencies, research and training institutions, programmes and funds and other UN entities. All organizations in the UN system obey the Noblemaire principle , which calls for salaries that will attract and retain citizens of countries where compensation is highest, and which ensures equal pay for work of equal value regardless of

8479-446: The UN's focus on promoting development, peacekeeping, human rights and global security. The Sustainable Development Goals (or SDGs) were launched in 2015 to succeed the Millennium Development Goals. In addition to addressing global challenges, the UN has sought to improve its accountability and democratic legitimacy by engaging more with civil society and fostering a global constituency. In an effort to enhance transparency, in 2016

8618-405: The UN's primary mandate was peacekeeping , the division between the United States and the Soviet Union often paralysed the organization; generally allowing it to intervene only in conflicts distant from the Cold War . Two notable exceptions were a Security Council resolution on 7 July 1950 authorizing a US-led coalition to repel the North Korean invasion of South Korea , passed in the absence of

8757-420: The UN, 16 of them from Africa. On 25 October 1971, with opposition from the United States, but with the support of many Third World nations, the People's Republic of China was given the Chinese seat on the Security Council in place of the Republic of China (also known as Taiwan). The vote was widely seen as a sign of waning American influence in the organization. Third World nations organized themselves into

8896-580: The United Nations can establish various specialized agencies to fulfill its duties. Specialized agencies are autonomous organizations working with the United Nations and each other through the coordinating machinery of the Economic and Social Council. Each was integrated into the UN system through an agreement with the UN under UN Charter article 57. There are fifteen specialized agencies, which perform functions as diverse as facilitating international travel, preventing and addressing pandemics, and promoting economic development. The United Nations system includes

9035-421: The United States' funding from the United Nations Educational, Scientific and Cultural Organisation (or UNESCO) over allegations of mismanagement, followed by the United Kingdom and Singapore. Boutros Boutros-Ghali , the secretary-general from 1992 to 1996, initiated a reform of the Secretariat, somewhat reducing the size of the organisation. His successor, Kofi Annan , initiated further management reforms in

9174-405: The advised evacuation zone. A professional video camera used by an NTV cameraman who died in the pyroclastic flow was discovered in June 2005. The camera melted due to the high temperature generated by the pyroclastic flow and was severely damaged, but the tape it contained was playable, despite having been buried under volcanic deposits for almost 15 years. The video received from the camera shows

9313-510: The assembly gathers at annual sessions at the General Assembly Hall , but emergency sessions can be summoned. The assembly is led by a president , elected by the member states on a rotating regional basis, and 21 vice-presidents. The first session convened on 10 January 1946 in the Methodist Central Hall in London and comprised representatives of 51 nations. When the General Assembly decides on seminal questions such as those on peace and security, admission of new members and budgetary matters,

9452-412: The basis of the Convention on the Privileges and Immunities of the United Nations , the UN and its agencies are immune from the laws of the countries where they operate, safeguarding the UN's impartiality with regard to host and member countries.

During World War I , several major leaders, especially U.S. President Woodrow Wilson , advocated for a world body to guarantee peace. The winners of the war, the Allies , met to decide on formal peace terms at

10008-503: The city council election poster bulletin board, and four residents who were working in agriculture were killed. The disaster resulted in 43 dead or missing, and nine injured. The photographer of the Yomiuri Shimbun newspaper died holding his Nikon F4. The camera recorded seven frames of the pyroclastic flow, although it was discolored by heat. All of the areas surrounding the "fixed point" where many casualties occurred, were within

10147-524: The companies started competing for color photographs. The competition became even more intense as the Mainichi Shimbun succeeded in shooting nightly pyroclastic flows on May 28. The fact that pyroclastic flows were being recorded in clear images for the first time attracted a great deal of attention from all over the world, and many volcanologists and government officials entered the evacuation advisory area for interviews and photography. On May 28,

10286-592: The council are known as United Nations Security Council resolutions . The Security Council is made up of fifteen member states: five permanent members (China, France, Russia, the United Kingdom and the United States) and ten non-permanent members (currently Algeria , Ecuador , Guyana , Japan , Malta , Mozambique , the Republic of Korea , Sierra Leone , Slovenia and Switzerland ). The five permanent members hold veto power over UN resolutions, allowing

10425-775: The crater of Galeras . An unexpected eruption while they were at the summit killed six scientists and three tourists. Civil unrest in the vicinity of several of the Decade Volcanoes has also interfered with the program. The civil war in Guatemala affected studies of Volcán Santa María until a ceasefire was called in 1996, while ongoing civil war in the Democratic Republic of the Congo has hampered studies of Nyiragongo volcano. More generally, scarce resources for volcano studies have led to programs competing for limited funding. The following volcanoes were selected as

10564-417: The crater. A pyroclastic flow triggered by the collapse of a lava dome reached 4.5 km (2.8 mi) from the crater and claimed the lives of 43 scientists and journalists, including volcanologists Katia and Maurice Krafft and Harry Glicken . The first debris flow in the Mizunashi River (located at the foothills of Unzendake) occurred on May 15, and others continued to occur in succession on

10703-492: The crater. On March 25, fumes rose and lava flowed down the northeastern part of Fugen-dake at a total length of 2.7 km (1.7 mi). Eventually, the east flank of the Mayu-yama dome collapsed unexpectedly following a post-eruption earthquake, creating a landslide into Ariake Bay . This caused a tsunami that killed an estimated 15,000 people. As of 2011 it is the worst volcanic related eruption in Japan. After 1792,

10842-831: The eighth secretary-general, Ban Ki-moon , the UN intervened with peacekeepers in crises such as the War in Darfur in Sudan and the Kivu conflict in the Democratic Republic of the Congo and sent observers and chemical weapons inspectors to the Syrian Civil War . In 2013, an internal review of UN actions in the final battles of the Sri Lankan Civil War in 2009 concluded that the organization had suffered

10981-421: The emplacement of large areas of pyroclastic flow and lahar deposits; these form the major part of the volcanic fan surrounding the volcano. Beginning 300,000 to 150,000 years ago, thick phreatomagmatic deposits were laid down, suggesting the subsidence of the volcano into its graben was rapid during this period. Activity from 150,000 years ago to the present has occurred at a number of sites around

11120-500: The employee's nationality. In practice, the International Civil Service Commission , which governs the conditions of UN personnel, takes reference to the highest-paying national civil service. Staff salaries are subject to an internal tax that is administered by the UN organizations. The General Assembly is the primary deliberative assembly of the UN. Composed of all UN member states ,

11259-541: The evacuation zone to perform flower filling work later than usual. Volcanologists did not talk about the danger of pyroclastic flows initially, because they feared residents would panic, especially those still working in the evacuated area. Residents were warned not to enter the evacuation advisory area by Shimabara City and the media, but since May, no concrete image was given regarding the danger of pyroclastic flows compared to that of debris flows (which had caused significant damage previously), and most residents did not take

11398-470: The experience of counterparts from industrialized countries. Also, civil defence leaders who have experienced volcanic crises are far more credible witnesses, in the eyes of local civil defence leaders, than either local or visiting scientists might be. Since it was initiated, the Decade Volcano program has achieved a number of successes in predicting volcanic events and mitigating disasters. One of

11537-484: The extent at which it burned." Twenty-five days after the event, the Japan Meteorological Agency revealed that while the first dome collapse was reported, much of the mass media and local residents were in a state of confusion about the danger of pyroclastic flows, and were not particularly concerned about them overall. The media originally reported that the pyroclastic flows seen on Fugen-dake at

11676-540: The face of threats from the US to withhold its UN dues. Though the UN Charter had been written primarily to prevent aggression by one nation against another, in the early 1990s the UN faced several simultaneous, serious crises within Somalia, Haiti, Mozambique, and the nations that previously made up Yugoslavia. The UN mission in Somalia was widely viewed as a failure after the United States' withdrawal following casualties in

11815-504: The failure of UN mediation in conflicts in the Middle East , Vietnam , and Kashmir , the UN increasingly shifted its attention to its secondary goals of economic development and cultural exchange. By the 1970s, the UN budget for social and economic development was far greater than its peacekeeping budget. After the Cold War, the UN saw a radical expansion in its peacekeeping duties, taking on more missions in five years than it had in

11954-422: The field of view was poor due to dispersing ash from the previous pyroclastic flow, as well as due to the presence of rain, and it was almost impossible to evacuate even from the windward side, as the pyroclastic surge that flowed from the Akamatsu-dani River would have cut them off. A fire brigade member of the agricultural training station, several hundred meters away from the "fixed point", assumed incorrectly that

12093-665: The firefighting station in Minami-Kamikoba town to the Shiratani Public Hall in the lower Mizunashi River, but on June 2, they returned to the Agricultural Training Center in Kita-Kamikoba town. This was because of the following reasons: On Sunday, June 2, all 20 members of the Kamikoba area fire brigade slept at the agricultural training institute. They remained at the training center and were on alert. After 3:30 pm on June 3, small and medium-sized pyroclastic flows occurred frequently, and

12232-415: The first debris flow caused by accumulated volcanic ash at the summit occurred, and a number of cracks were formed on the west side of the crater, extending in an east–west direction. After this inflation of the summit area, fresh lava was confirmed to be emerging on May 20, 1991. The lava was so viscous that it did not flow out, but instead became a dome which formed in the crater. The lava dome grew like

12371-423: The first eruptive activities in the world where pyroclastic flows were recorded clearly and continuously on video (in the past, many pyroclastic flows, such as those on Mt. Pelee, were recorded either as photographs or on small-scale videos). Dome collapses and pyroclastic flows continued. The first large-scale dome collapses and pyroclastic flows occurred after June 3 on September 15, 1991. Progressive failure of

12510-421: The first large-scale pyroclastic flow occurred at 3:57. Although this pyroclastic flow (and its resulting pyroclastic surge) did not reach the "fixed point", visibility in the vicinity deteriorated significantly as volcanic ash from the dispersing cloud covered the surroundings, in addition to the rainfall that had continued from the morning. At 4:08 pm, the second large pyroclastic flow occurred, descending

12649-778: The five principal organs are located at the main UN Headquarters in New York City, while the International Court of Justice is seated in The Hague . Most other major agencies are based in the UN offices at Geneva , Vienna , and Nairobi , and additional UN institutions are located throughout the world. The six official languages of the UN, used in intergovernmental meetings and documents, are Arabic , Chinese , English , French , Russian and Spanish . On

12788-503: The generating pyroclastic flow, and asks "What's that sound?", whilst turning the camera in the direction of Mt. Fugen). This video was broadcast on October 16, 2005, and is now exhibited at the Unzendake Disaster Memorial Hall (Shimabara City) alongside the melted camera. It is unclear as to what caused the unprecedented size of the second, large-scale pyroclastic flow on June 3. It has been suggested that

12927-457: The heavy ash-laden column that towered over the main flow, collapsed during its descent, causing the surge. It has also been pointed out that when the dome collapsed, 0.5 million cubic meters of hardened lava broke off, leaving a significant collapse scar afterwards, suggesting that the size of the dome collapse (rather than the column collapse) initiated the surge. Other explanations account the fact that previous lahars and pyroclastic flows filled

13066-503: The intense heat of the ash. Pictures have shown that the pyroclastic flow left significant deposits near the mouth of the Mizunashi River Valley, enough to bury houses and the river itself. In contrast, the surge that detached from the flow left deposits of ash between 3 and 30 centimetres (1.2 and 11.8 in) thick, however trees were flattened and many buildings continued burning until the next morning. The force of

13205-481: The largest gathering of world leaders in history, and it culminated in the adoption by all member states of the Millennium Development Goals (or MDGs), a commitment to achieve international development in areas such as poverty reduction , gender equality and public health . Progress towards these goals, which were to be met by 2015, was ultimately uneven. The 2005 World Summit reaffirmed

13344-570: The major strengths and weaknesses of risk mitigation at each volcano, and to plan how to address the weaknesses identified. One of the difficulties faced in mitigating hazards at volcanoes is ensuring that geoscientists and those who will enact the mitigation measures communicate adequately with each other, and the Decade Volcano program has attempted to ensure this by making sure both groups are well represented at Decade Volcano workshops. Hopes that United Nations funding might be available for Decade Volcano projects did not come to fruition, and funding

13483-401: The most notable was the successful diversion of a lava flow and blanket at Mount Etna in 1992. The flow was threatening the town of Zafferana , and had overwhelmed several barriers placed perpendicular to its flow down a valley . Scientists and civil defence leaders decided to try to dam the flow higher up, and did so by dropping large concrete blocks into a skylight in a lava tube which

13622-461: The organization are five principal organs established by the UN Charter: the General Assembly , the Security Council , the Economic and Social Council , the International Court of Justice and the UN Secretariat . A sixth principal organ, the Trusteeship Council , suspended its operations on 1 November 1994 upon the independence of Palau ; the last remaining UN trustee territory. Four of

13761-506: The organization held its first public debate between candidates for secretary-general. On 1 January 2017, Portuguese diplomat António Guterres , who had previously served as the UN High Commissioner for Refugees , became the ninth secretary-general. Guterres has highlighted several key goals for his administration, including an emphasis on diplomacy for preventing conflicts, more effective peacekeeping efforts, and streamlining

13900-482: The organization to be more responsive and versatile to international needs. On 13 June 2019, the UN signed a Strategic Partnership Framework with the World Economic Forum in order to "jointly accelerate" the implementation of the 2030 Agenda for Sustainable Development . The United Nations is part of the broader UN System, which includes an extensive network of institutions and entities. Central to

14039-479: The original target depth, without reaching the conduit, but in July 2004 at a depth of 1,995 metres (6,545 ft), the conduit was finally reached. The vertical depth below the summit was 1,500 metres (4,900 ft). The temperature at the conduit was about 155 °C (311 °F), much lower than pre-drill estimations of 500 °C (932 °F) and over. This was attributed to hydrothermal circulation accelerating

14178-405: The photographer who had been lowered backwards was advanced to the Kamikoba area once again on June 1. The evacuation area then became smaller, since the commercial broadcasters had shot footage of bright red lava on May 30 and 31; the person in charge of the news program (who ordered the initial retreat of the front-line shooting staff) ordered more images shot like it. Kamikoba soon emerged again as

14317-471: The plenary meetings. Previously, Churchill had urged Roosevelt to restore France to its status of a major power after the liberation of Paris in August 1944. The drafting of the Charter of the United Nations was completed over the following two months, and it was signed on 26 June 1945 by the representatives of the 50 countries. The UN officially came into existence on 24 October 1945, upon ratification of

14456-502: The plumes. In particular, since June 2 was Sunday, many visitors from other prefectures gathered around the Mizunashi River and observed the pyroclastic flows with binoculars and photographed them with video cameras. Traffic became heavy as a result. However, on May 26, reporters from the Asahi Shimbun were warned that it was likely for them to be engulfed by the clouds, and in an evacuation recommendation, they were asked to leave

14595-553: The post, but over the years it has become accepted that the position shall be held for one or two terms of five years. The current secretary-general is António Guterres of Portugal, who replaced Ban Ki-moon in 2017. The International Court of Justice (or ICJ), sometimes known as the World Court, is the primary judicial organ of the UN. It is the successor to the Permanent Court of International Justice and occupies

14734-653: The post-war world. At the subsequent meeting of the Inter-Allied Council in London on 24 September 1941, the eight governments in exile of countries under Axis occupation , together with the Soviet Union and representatives of the Free French Forces , unanimously adopted adherence to the common principles of policy set forth by Britain and the United States. Roosevelt and Churchill met at

14873-560: The presence of Russian troops in Iranian Azerbaijan and British forces in Greece . British diplomat Gladwyn Jebb served as interim secretary-general. The General Assembly selected New York City as the site for the headquarters of the UN. Construction began on 14 September 1948 and the facility was completed on 9 October 1952. The Norwegian Foreign Minister, Trygve Lie , was the first elected UN secretary-general . Though

15012-532: The previous four decades. Between 1988 and 2000, the number of adopted Security Council resolutions more than doubled, and the peacekeeping budget increased by more than tenfold. The UN negotiated an end to the Salvadoran Civil War , launched a successful peacekeeping mission in Namibia , and oversaw democratic elections in post- apartheid South Africa and post- Khmer Rouge Cambodia. In 1991,

15151-428: The reporters observing the first pyroclastic flow, and then continuing to report after having moved their position to the "fixed point". It also displays the police cars that announced evacuation, all unaware of the approach of the second large pyroclastic flow. The footage and sound were recorded and recovered, although heavily damaged and warped (the video ends when the cameraman notices a sound apparently associated with

15290-554: The residents in the Kamikoba area recognized pyroclastic flows as "very dangerous". As was seen in the survey results, the volcanologist's warnings were not even understood by residents living in the most dangerous areas. On June 3, a debris flow warning was passed out due to rain that began in the morning, and a party was held in Shiratani to celebrate the winner of the Shimabara City Council election on June 2. As

15429-429: The residents' request that patrolling police officers allow them into the area to return to their homes (in preparation for prolonged evacuation). From the same day onward, a "district name sticker" was issued, and private cars with such a sticker were given permission to enter the evacuated area. For this reason, there were many residents doing laundry and field work at homes in the zone that had been declared dangerous. In

15568-469: The river, fragmenting the ash-particles of the avalanche and expanding the energy of the overlaying gas and ash cloud. Pyroclastic flows continued over the next few days following the June 3 eruption, however, they were reportedly smaller and less frequent. Even so, rescue efforts and movements to recover the bodies of the victims, were disrupted and stalled due to the ever-present danger. Authorities eventually managed to recover 27 bodies and brought them to

15707-629: The roaring of the pyroclastic flow was caused by a debris flow instead, and was engulfed by the pyroclastic surge when he left the training station to check the Mizunashi River. Many members escaped from the evacuation advisory area on their own, but suffered severe burns and airway damage. As a result, 16 members of the media (including part-time students), three volcanologists (the Kraffts and Harry Glicken), 12 firefighters who were on guard, four taxi drivers, two police officers who came by police car to conduct evacuation guidance, two workers who were removing

15846-490: The same conduits despite the solidification of magma in them at the end of each eruption, and how it can lose enough gas on its ascent to erupt effusively rather than explosively. Drilling began with test bores to assess the viability of a deep borehole . Two holes were drilled, 750 metres (2,460 ft) and 1,500 metres (4,900 ft) deep, and cores taken from these holes were used to better determine Unzen's eruptive history. One further 350-metre (1,150 ft) deep borehole

15985-402: The slope, causing a phenomenon known as pyroclastic flows (in which debris and volcanic gasses flow down the mountainside at speeds of 100 km/h). The threat of further disastrous events prompted authorities to evacuate 12,000 residents from their homes. On June 3, 1991, the volcano erupted violently, possibly as a result of depressurisation of the magma column after a landslide in

16124-465: The south of today's Mount Unzen and migrated north over time. The volcano rapidly grew during its first 200,000 years, forming a very large cone. Later eruptions over the following 150,000 years filled in much of the graben. Initially, activity was dominated by blocky andesitic lava and ash flows, changing to dacitic pumice flows and airfall deposits from 500,000 to 400,000 years ago. The period from 400,000 to 300,000 years ago saw

16263-645: The spring of the following year, there was a flood from the Kujuku Island crater, located on the southeastern flank of Fugen-dake at an altitude of 600 metres (2,000 ft). More than 30 were killed. Unzen's deadliest eruption occurred in 1792 , beginning with an earthquake in November of the previous year. On February 10, 1792, eruptions from Fugen-dake's Jigokuato crater began. Lava flows began on March 1 and continued for nearly two months. On March 22, volcanic plumes were produced, and lava also flowed out of

16402-457: The summit. Finally on November 17, 1990 (Heisei 2), the first phreatic, or steam-blast, eruptions began ejecting from two places near a shrine at the summit. These eruptions only allowed vaporized hot water and ash to blow up from the two craters. In December of the same year, the volcano's state lulled and it seemed that it would end, but it erupted again on February 12, 1991, and on April 3 and 4. The eruption intensified on May 9. On May 15,

16541-519: The surge was enough to push a car 80 metres (260 ft) down-road. Many of the casualties of the June 3 eruption could have been avoided if the danger of pyroclastic flows had been made more apparent beforehand. While the first pyroclastic flow on May 24 was shocking, many did not understand just how lethal such events could become. A reporter stated at the time: "I knew they were quite hot, but didn't know they could be accompanied by (pyroclastic surges). I thought we could escape by car, but I didn't know

16680-408: The time were "geologically small", which many regarded as "a scale that would cause no human fatalities". On May 26, a construction worker operating a Sabo dam in the upstream area of the Mizunashi River was caught in a pyroclastic flow; he survived but was sent to hospital with burns on his arms. Many thought that such burns could be prevented by wearing a long-sleeved shirt. The danger of the phenomena

16819-691: The usage of only eight mountains (sometimes three mountains) was coined in a narrow sense, but historically it is a name that refers to the entire mountain range towering over the sea. It is often confused with the name of the oldest peak, Fugen-dake . Surrounding the highest peak of Heisei-shinzan (1,483 m (4,865 ft)), are Fugen-dake (1,359 m (4,459 ft)), Kunimi-dake (1,347 m (4,419 ft)), Myoken-dake (1,333 m (4,373 ft)), Nodake (1,142 m (3,747 ft)), Kusenbedake (1,062 m (3,484 ft)), and Yadake (943 m (3,094 ft)). Fugen-dake and Heisei-shinzan derive magma from

16958-484: The village of Kita-Kamikoba, and was favored by the media because they were able to view Fugen-dake directly in front of them. The nickname "fixed point" was established. After the first pyroclastic flow on May 24, more than a dozen media members were lined up at the "fixed point". In 1991, the media had started to use color photographs on the paper, and with the Fugen-dake disaster becoming an ongoing topic of coverage,

17097-591: The volcanic complex, building four main domes at different times: the No-dake (70–150,000 years old), Myōken-dake (25–40,000 years old), Fugen-dake (younger than 25,000 years old) and Mayu-yama (4,000 years old) volcanic peaks. Fugen-dake has been the site of most eruptions during the past 20,000 years and lies about 6 kilometres (3.7 mi) from the center of Shimabara. In December 1663, Fugen-dake erupted, producing lava flows that covered forest for over an extension of 1 km (0.62 mi). In

17236-440: The volcano remained dormant until it erupted again in November 1990. It started with a slowly building active phase in 1968, with first earthquake swarms continuing until 1975. Large amounts of volcanic gas were ejected by Fugen, which affected about thirty cedar trees. In 1975, bird and animal carcasses were found in the surrounding area, and high concentrations of carbon dioxide were detected emitting from rock fractures. This area

17375-409: The warnings seriously. Many misunderstood them to be mere clouds of dust. According to the "Investigation of Disaster Information Transmission and Residents' Responses during the 1991 Unzendake Eruption" conducted in 1992, 75% of local residents recognized debris flows as more dangerous than pyroclastic flows before June 2. Only 15% perceived pyroclastic flows to be more dangerous. Furthermore, only 5% of

17514-457: The whole peninsula between 2.5 and 0.5 million years ago. The origins of the Unzen complex are traced to the formation of a graben through crustal faulting. This caused parts of the peninsula to subside by up to 1,000 metres (3,300 ft) below sea level and may have caused eruptive activity to localize at one site inside the graben. Eruptions of dacitic lava began from a site slightly to

17653-416: The widespread decolonization in the 1960s. Since then, 80 former colonies have gained independence, including 11 trust territories that had been monitored by the Trusteeship Council . By the 1970s, the UN's budget for economic and social development programmes vastly exceeded its spending on peacekeeping . After the end of the Cold War in 1991, the UN shifted and expanded its field operations, undertaking

17792-404: The world stage. The office has evolved into a dual role of an administrator of the UN organization and a diplomat and mediator addressing disputes between member states and finding consensus to global issues . The secretary-general is appointed by the General Assembly, after being recommended by the Security Council, where the permanent members have veto power. There are no specific criteria for

17931-540: Was also reported to have erupted volcanic gasses during the 1792 eruption. Earthquakes occurred sporadically from 1975, but there were 89 sensitive earthquakes, with strong shaking equivalent to a maximum seismic intensity of 5 from June to September 1979. At Shimabara Onsen, there was a place where the dissolved carbon dioxide concentration rose sharply from 1975 and increased by 30%. From April 1984, swarms occurred in Tachibana Bay  A magnitude 5.7 earthquake with

18070-413: Was carried out without trouble. In order to capture the pyroclastic flow activity on film, the mass media chose a select spot within the evacuation advisory area. This spot was 4 km (2.5 mi) away from the lava dome, 700 m (2,300 ft) away from the Mizunashi River (where debris flows were frequent), and 40 m (130 ft) high. This shooting spot was located on the prefectural road in

18209-564: Was changed to the current notation when it was designated as a national park. An army radar base was built near the summit of Fugen-dake during the Pacific War, where about 100 people were stationed. Mount Unzen is part of the Shimabara Peninsula , which has seen extensive volcanism over millions of years. The oldest volcanic deposits in the region date from over 6 million years ago, and extensive eruptions occurred over

18348-685: Was concern about the collapse of Mt. Mayuyama, which previously caused the 1792 disaster. In this eruptive activity, however, Mt. Mayuyama protected the center of Shimabara from the pyroclastic flows. In areas other than Shimabara and Fukae, there was ash fall depending on the wind direction, and at Kumamoto Airport, it had an impact on the arrival and departure of aircraft. Since the eruptions, heavy rains have frequently remobilised pyroclastic material, generating lahars . Dikes have been constructed in several river valleys to channel lahar flows away from vulnerable areas, and warning systems and evacuation plans have been developed and deployed. Mount Unzen

18487-480: Was designated a Decade Volcano by the United Nations , in 1991 as part of their International Decade for Natural Disaster Reduction , due to its history of violent activity and location in a densely populated area. In 1999, an ambitious project began at Mount Unzen to drill deep inside the volcano and sample magma in the 1990–1995 eruption conduit . The project hoped to shed light on some fundamental questions in volcanology, such as why magma repeatedly travels in

18626-441: Was drilled to test the methods to be used in the final drilling project. The main drill began in 2003, starting from the northern flank of the volcano with a 440 mm (17 in) hole at an angle of 25 degrees from vertical. At greater depths, the direction of boring was tilted towards the conduit, reaching an angle of 75 degrees from vertical at a depth of 800 metres (2,600 ft). Drilling reached 1,800 metres (5,900 ft),

18765-518: Was feeding the flow. The flow subsequently stopped short of Zafferana. The program has significantly increased what is known about the Decade Volcanoes, some of which were very poorly studied before being designated. The eruptive history of Galeras volcano is now much better established than previously, and at Taal Volcano the importance of water in driving its explosive eruptions has come to light. Measures which have been taken to mitigate disasters which might be caused by future eruptions include

18904-444: Was most recently active from 1990 to 1995, and a large eruption in 1991 generated a pyroclastic flow that killed 43 people, including three volcanologists . Its highest peaks are Fugen-dake ( 普賢岳 ) at 1,359 metres (4,459 ft) and Heisei-shinzan ( 平成新山 ) at 1,486 metres (4,875 ft). The latter emerged during the eruptions of the early, eponymous Heisei era (1989–2019). Mount Unzen (or Unzen-dake ) rises in

19043-410: Was not made clear. Furthermore, the number of pyroclastic flows from May 25 to June 2 had increased to 165, and all had stopped near the Sabo dam in the upper reaches of the valley. As a result, much of the media grew accustomed to the eruptions and no longer felt like they were in any danger. Shimabara City issued an evacuation advisory for the villages near the base of Unzen on May 26, but responded to

19182-447: Was re-elected on 8 June 2021. The organization is financed by assessed and voluntary contributions from its member states. The UN, its officers, and its agencies have won multiple Nobel Peace Prizes , although other evaluations of its effectiveness have been contentious. Some commentators believe the organization to be a leader in peace and human development, while others have criticized it for ineffectiveness, bias, and corruption . In

19321-543: Was sought instead from a variety of sources. For example, Mexican scientific and civil defence bodies funded work at Colima , principally for Mexican scientists but also for a few foreign colleagues; major bilateral French-Indonesian and German-Indonesian programs were initiated at Merapi ; and the European Union has provided funding for many of the studies carried out at European volcanoes. One particular activity that has not been funded—because it typically
