Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift , the Wells Gray-Clearwater volcanic field , and the Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from

Herodotus gave a famous account of what defined Greek (Hellenic) ethnic identity in his day, enumerating By Western standards, the term Greeks has traditionally referred to any native speakers of the Greek language , whether Mycenaean , Byzantine or modern Greek . Byzantine Greeks self-identified as Romaioi ("Romans"), Graikoi ("Greeks") and Christianoi ("Christians") since they were

Today, Greeks are the majority ethnic group in the Hellenic Republic , where they constitute 93% of the country's population, and the Republic of Cyprus where they make up 78% of the island's population (excluding Turkish settlers in the occupied part of
1253-729: A break during the Greek Dark Ages from which written records are absent (11th- 8th cent. BC, though the Cypriot syllabary was in use during this period). Scholars compare its continuity of tradition to Chinese alone. Since its inception, Hellenism was primarily a matter of common culture and the national continuity of the Greek world is a lot more certain than its demographic. Yet, Hellenism also embodied an ancestral dimension through aspects of Athenian literature that developed and influenced ideas of descent based on autochthony. During

Homer refers to the "Hellenes" ( / ˈ h ɛ l iː n z / ) as a relatively small tribe settled in Thessalic Phthia , with its warriors under the command of Achilleus . The Parian Chronicle says that Phthia was the homeland of

Additionally, among the Germanic and the Slavic peoples, the Rhōmaîoi were just called Greeks. There are three schools of thought regarding this Byzantine Roman identity in contemporary Byzantine scholarship : The first considers "Romanity"
1790-494: A direct consequence of this situation, Greek-speakers came to play a hugely important role in the Ottoman trading and diplomatic establishment, as well as in the church. Added to this, in the first half of the Ottoman period men of Greek origin made up a significant proportion of the Ottoman army, navy, and state bureaucracy, having been levied as adolescents (along with especially Albanians and Serbs ) into Ottoman service through

The USGS defines a volcano as "erupting" whenever the ejection of magma from any point on the volcano is visible, including visible magma still contained within the walls of the summit crater. While there is no international consensus among volcanologists on how to define an active volcano,

In ancient and medieval times and to some extent today the Greek term was genos , which also indicates a common ancestry. Greeks and Greek-speakers have used different names to refer to themselves collectively. The term Achaeans (Ἀχαιοί)

It suggested that a volcano be defined as 'an opening on a planet or moon's surface from which magma , as defined for that body, and/or magmatic gas is erupted.' This article mainly covers volcanoes on Earth. See § Volcanoes on other celestial bodies and cryovolcano for more information. The word volcano

The large Greek diaspora and merchant class were instrumental in transmitting the ideas of western romantic nationalism and philhellenism , which together with the conception of Hellenism, formulated during the last centuries of the Byzantine Empire , formed the basis of the Diafotismos and the current conception of Hellenism. The Greeks today are

#17327718361613938-632: A volcano is largely determined by the composition of the lava it erupts. The viscosity (how fluid the lava is) and the amount of dissolved gas are the most important characteristics of magma, and both are largely determined by the amount of silica in the magma. Magma rich in silica is much more viscous than silica-poor magma, and silica-rich magma also tends to contain more dissolved gases. Lava can be broadly classified into four different compositions: Mafic lava flows show two varieties of surface texture: ʻAʻa (pronounced [ˈʔaʔa] ) and pāhoehoe ( [paːˈho.eˈho.e] ), both Hawaiian words. ʻAʻa
4117-555: A volcano is of a conical mountain, spewing lava and poisonous gases from a crater at its summit; however, this describes just one of the many types of volcano. The features of volcanoes are varied. The structure and behaviour of volcanoes depend on several factors. Some volcanoes have rugged peaks formed by lava domes rather than a summit crater while others have landscape features such as massive plateaus . Vents that issue volcanic material (including lava and ash ) and gases (mainly steam and magmatic gases) can develop anywhere on
4296-465: A volcano that has experienced one or more eruptions that produced over 1,000 cubic kilometres (240 cu mi) of volcanic deposits in a single explosive event. Such eruptions occur when a very large magma chamber full of gas-rich, silicic magma is emptied in a catastrophic caldera -forming eruption. Ash flow tuffs emplaced by such eruptions are the only volcanic product with volumes rivalling those of flood basalts . Supervolcano eruptions, while

Based on satellite images, it has been suggested that cinder cones might occur on other terrestrial bodies in the Solar system too; on the surface of Mars and the Moon. Stratovolcanoes (composite volcanoes) are tall conical mountains composed of lava flows and tephra in alternate layers, the strata that gives rise to the name. They are also known as composite volcanoes because they are created from multiple structures during different kinds of eruptions. Classic examples include Mount Fuji in Japan, Mayon Volcano in
4833-523: Is a popular tourist destination, welcoming up to 6 million visitors per year, mainly from the Italian mainland as well as other European countries like Germany and the United Kingdom (approximately 5,000 Germans are resident on the island), although it has become an increasingly popular destination for Eastern Europeans. The number of Russian guests rose steadily from the 2000s onwards, before

While the Greeks of the classical era understood themselves to belong to a common Hellenic genos , their first loyalty was to their city and they saw nothing incongruous about warring, often brutally, with other Greek city-states . The Peloponnesian War ,

Pāhoehoe is characterized by its smooth and often ropey or wrinkly surface and is generally formed from more fluid lava flows. Pāhoehoe flows are sometimes observed to transition to ʻaʻa flows as they move away from the vent, but never the reverse. More silicic lava flows take the form of block lava, where

Tuya Butte was the first such landform analysed and so its name has entered the geological literature for this kind of volcanic formation. The Tuya Mountains Provincial Park was recently established to protect this unusual landscape, which lies north of Tuya Lake and south of the Jennings River near

The Hawaiian volcanic chain is a series of shield cones, and they are common in Iceland , as well. Lava domes are built by slow eruptions of highly viscous lava. They are sometimes formed within the crater of a previous volcanic eruption, as in the case of Mount St. Helens , but can also form independently, as in
7160-733: The Graikoi (Γραικοί) were named Hellenes. Aristotle notes in his Meteorologica that the Hellenes were related to the Graikoi. The English names Greece and Greek are derived, via the Latin Graecia and Graecus , from the name of the Graeci ( Γραικοί , Graikoí ; singular Γραικός , Graikós ), who were among the first ancient Greek tribes to settle southern Italy (the so-called " Magna Graecia "). The term

Hotspots are volcanic areas thought to be formed by mantle plumes , which are hypothesized to be columns of hot material rising from the core-mantle boundary. As with mid-ocean ridges, the rising mantle rock experiences decompression melting which generates large volumes of magma. Because tectonic plates move across mantle plumes, each volcano becomes inactive as it drifts off
8234-483: The Etruscans of the mainland. This settlement was home to a mixed population of Greeks, Etruscans , and Phoenicians . Because of its fine harbor and the safety from raids afforded by the sea, the settlement of Pithecusae became successful through trade in iron and with mainland Italy; in 700 BC Pithecusae was home to 5,000–10,000 people. The ceramic Euboean artifact inscribed with a reference to " Nestor's Cup "

13425-574: The Grim ( r. 1517–1520), whose mother Gülbahar Hatun was a Pontic Greek . The roots of Greek success in the Ottoman Empire can be traced to the Greek tradition of education and commerce exemplified in the Phanariotes . It was the wealth of the extensive merchant class that provided the material basis for the intellectual revival that was the prominent feature of Greek life in
13604-570: The Hellenes and that this name was given to those previously called Greeks ( Γραικοί ). In Greek mythology , Hellen , the patriarch of the Hellenes who ruled around Phthia, was the son of Pyrrha and Deucalion , the only survivors after the Great Deluge . The Greek philosopher Aristotle names ancient Hellas as an area in Epirus between Dodona and the Achelous river, the location of
13783-653: The Homeric tradition of ancient Greece. A distinct Greek identity re-emerged in the 11th century in educated circles and became more forceful after the fall of Constantinople to the Crusaders of the Fourth Crusade in 1204. In the Empire of Nicaea , a small circle of the elite used the term "Hellene" as a term of self-identification. For example, in a letter to Pope Gregory IX , the Nicaean emperor John III Doukas Vatatzes (r. 1221–1254) claimed to have received
13962-529: The Indo-Greek kingdoms lasted for a few more decades. This age saw the Greeks move towards larger cities and a reduction in the importance of the city-state. These larger cities were parts of the still larger Kingdoms of the Diadochi . Greeks, however, remained aware of their past, chiefly through the study of the works of Homer and the classical authors. An important factor in maintaining Greek identity
14141-407: The Ischia DOC are composed of 50% Guarnaccia , 40% Piedirosso (known under the local synonym of Per'e Palummo) and 10% Barbera . Like the white wines, red grapes destined for DOC production are limited to a harvest yield of no more than 10 tonnes/ha though the minimum finished alcohol level is higher at 11.5% ABV. The Aragonese Castle ( Castello Aragonese , Ischia Ponte) was built on a rock near
14320-597: The Mediterranean Sea, designated as a ‘priority habitat’ in Annex I to the Habitats Directive (92/43/EEC) and comprising oceanic posidonia beds. To reduce pollution due to cars, Ischia has been the place of the first complete sustainable mobility project applied to an urban center, created in 2017 with Enel in collaboration with Aldo Arcangioli , one the main Italian experts of green mobility, under
14499-723: The Middle Ages, the Byzantine Greeks self-identified as Rhōmaîoi ( Ῥωμαῖοι , "Romans", meaning citizens of the Roman Empire ), a term which in the Greek language had become synonymous with Christian Greeks. The Latinizing term Graikoí (Γραικοί, "Greeks") was also used, though its use was less common, and nonexistent in official Byzantine political correspondence, prior to the Fourth Crusade of 1204. The Eastern Roman Empire (today conventionally named
14678-531: The Mycenaean heritage that survived, the names of the gods and goddesses of Mycenaean Greece (e.g. Zeus , Poseidon and Hades ) became major figures of the Olympian Pantheon of later antiquity. The ethnogenesis of the Greek nation is linked to the development of Pan-Hellenism in the 8th century BC. According to some scholars, the foundational event was the Olympic Games in 776 BC, when
14857-622: The Philippines, and Mount Vesuvius and Stromboli in Italy. Ash produced by the explosive eruption of stratovolcanoes has historically posed the greatest volcanic hazard to civilizations. The lavas of stratovolcanoes are higher in silica, and therefore much more viscous, than lavas from shield volcanoes. High-silica lavas also tend to contain more dissolved gas. The combination is deadly, promoting explosive eruptions that produce great quantities of ash, as well as pyroclastic surges like
15036-476: The Roman Empire. Despite their military superiority, the Romans admired and became heavily influenced by the achievements of Greek culture, hence Horace 's famous statement: Graecia capta ferum victorem cepit ("Greece, although captured, took its wild conqueror captive"). In the centuries following the Roman conquest of the Greek world, the Greek and Roman cultures merged into a single Greco-Roman culture. In
15215-526: The Tyrrhenian coasts" certainly played a part. On the other hand, the modern "Island of Ischia" could derive from the Latin "insula visca" – compare the Greek noun (ϝ)ἰξός, (w)ixós, (mistletoe) and the adjective (ϝ)ἰξώδης, (w)ixṓdēs, (viscous, sticky), which as usual have lost the initial digamma. In favor of this theory could be the fact that in the same area, at the foot of Vesuvius covered with pines ,
15394-613: The USGS defines a volcano as active whenever subterranean indicators, such as earthquake swarms , ground inflation, or unusually high levels of carbon dioxide or sulfur dioxide are present. The USGS defines a dormant volcano as any volcano that is not showing any signs of unrest such as earthquake swarms, ground swelling, or excessive noxious gas emissions, but which shows signs that it could yet become active again. Many dormant volcanoes have not erupted for thousands of years, but have still shown signs that they may be likely to erupt again in
15573-576: The West during the 15th century, giving the Italian Renaissance a major boost. The Aristotelian philosophical tradition was nearly unbroken in the Greek world for almost two thousand years, until the Fall of Constantinople in 1453. To the Slavic world, the Byzantine Greeks contributed by the dissemination of literacy and Christianity. The most notable example of the later was the work of
15752-614: The aid of the Cumaeans, who lived on the mainland opposite Ischia, against the Etruscans and defeated them on the sea. He occupied Ischia and the surrounding Parthenopean islands and left behind a garrison to build a fortress before the city of Ischia itself. This was still extant in the Middle Ages , but the original garrison fled before the eruptions of 470 BC and the island was taken over by Neapolitans. The Romans seized Ischia (and Naples) in 322 BC. In 6 AD, Augustus restored
15931-510: The boundary with the Yukon Territory . Mud volcanoes (mud domes) are formations created by geo-excreted liquids and gases, although several processes may cause such activity. The largest structures are 10 kilometres in diameter and reach 700 meters high. The material that is expelled in a volcanic eruption can be classified into three types: The concentrations of different volcanic gases can vary considerably from one volcano to
16110-402: The case of Lassen Peak . Like stratovolcanoes, they can produce violent, explosive eruptions, but the lava generally does not flow far from the originating vent. Cryptodomes are formed when viscous lava is forced upward causing the surface to bulge. The 1980 eruption of Mount St. Helens was an example; lava beneath the surface of the mountain created an upward bulge, which later collapsed down
16289-481: The castle and gave the island over, in 1462, to Garceraldo Requesens. In 1464, after a brief Torellan insurrection, Marino Caracciolo was set up as governor. In February 1495, with the arrival of Charles VIII , Ferdinand II landed on the island and took possession of the castle, and, after having killed the disloyal castellan Giusto di Candida with his own hands, left the island under the control of Innico d'Avalos , marquis of Pescara and Vasto , who ably defended
16468-603: The city of Athens. Greeks from Cyprus have a similar history of emigration, usually to the English-speaking world because of the island's colonization by the British Empire . Waves of emigration followed the Turkish invasion of Cyprus in 1974, while the population decreased between mid-1974 and 1977 as a result of emigration, war losses, and a temporary decline in fertility. After the ethnic cleansing of
16647-580: The command of Lord Nelson had put down the revolt on Ischia as well as on neighboring Procida . By decree of the governor, many of the rebels were hanged in a square on Procida now called Piazza dei martiri (Square of the Martyrs). Among these was Francesco Buonocore who had received the island to administer from the French Championnet in Naples. On February 13, 1806, the island was occupied by
16826-430: The construction of houses and residential structures. Most of this development has taken place without any planning and building permission. As at the end of 2011, the island lacked the most basic system for sewage treatment; sewage is sent directly to the sea. In 2004 one of the five communities of the island commenced civil works to build a sewage treatment plant but since then the construction has not been completed and it
17005-406: The country). Greek populations have not traditionally exhibited high rates of growth; a large percentage of Greek population growth since Greece's foundation in 1832 was attributed to annexation of new territories, as well as the influx of 1.5 million Greek refugees after the 1923 population exchange between Greece and Turkey. About 80% of the population of Greece is urban, with 28% concentrated in
17184-579: The creation of colonies and trade routes along the way. While the Alexandrian empire did not survive its creator's death intact, the cultural implications of the spread of Hellenism across much of the Middle East and Asia were to prove long lived as Greek became the lingua franca , a position it retained even in Roman times . Many Greeks settled in Hellenistic cities like Alexandria , Antioch and Seleucia . The Hellenistic civilization
17363-400: The descendants of Greeks and Romans. Before the establishment of the modern Greek nation-state, the link between ancient and modern Greeks was emphasized by the scholars of Greek Enlightenment especially by Rigas Feraios. In his "Political Constitution", he addresses to the nation as "the people descendant of the Greeks". The modern Greek state was created in 1829, when the Greeks liberated
17542-715: The disturbances many set up home around the Mediterranean (notably Marseilles in France , Livorno in Italy , Alexandria in Egypt ), Russia ( Odesa and Saint Petersburg ), and Britain (London and Liverpool) from where they traded, typically in textiles and grain. Businesses frequently comprised the extended family, and with them they brought schools teaching Greek and the Greek Orthodox Church . As markets changed and they became more established, some families grew their operations to become shippers , financed through
17721-405: The eastern coast, under the castle. The first evidence of the island's current toponym dates back to the year 812 , in a letter from Pope Leo III in which he informs Emperor Charlemagne of devastations that occurred in the area, calling the island Iscla maior: "Ingressi sunt ipsi nefandissimi Mauri [...] in insulam, quae dicitur Iscla maiore, non longe a Neapolitana urbe." Some scholars connect
17900-859: The enormous area they cover, and subsequent concealment under vegetation and glacial deposits, supervolcanoes can be difficult to identify in the geologic record without careful geologic mapping . Known examples include Yellowstone Caldera in Yellowstone National Park and Valles Caldera in New Mexico (both western United States); Lake Taupō in New Zealand; Lake Toba in Sumatra , Indonesia; and Ngorongoro Crater in Tanzania. Volcanoes that, though large, are not large enough to be called supervolcanoes, may also form calderas in
18079-589: The first and oldest written evidence of Greek . The Mycenaeans quickly penetrated the Aegean Sea and, by the 15th century BC, had reached Rhodes , Crete , Cyprus and the shores of Asia Minor . Around 1200 BC, the Dorians , another Greek-speaking people, followed from Epirus . Older historical research often proposed Dorian invasion caused the collapse of the Mycenaean civilization , but this narrative has been abandoned in all contemporary research. It
18258-431: The flow is covered with angular, vesicle-poor blocks. Rhyolitic flows typically consist largely of obsidian . Tephra is made when magma inside the volcano is blown apart by the rapid expansion of hot volcanic gases. Magma commonly explodes as the gas dissolved in it comes out of solution as the pressure decreases when it flows to the surface . These violent explosions produce particles of material that can then fly from
18437-404: The following year. In 1422 Joan II gave the island to her adoptive son Alfonso V of Aragon , though, when he fell into disgrace, she retook it with the help of Genoa in 1424. In 1438 Alfonso reoccupied the castle, kicking out all the men and proclaiming it an Aragonese colony, marrying to his garrison the wives and daughters of the expelled. He set about building a bridge linking the castle to
18616-610: The formation of a submarine volcano off the coast of Mayotte . Subglacial volcanoes develop underneath ice caps . They are made up of lava plateaus capping extensive pillow lavas and palagonite . These volcanoes are also called table mountains, tuyas , or (in Iceland) mobergs. Very good examples of this type of volcano can be seen in Iceland and in British Columbia . The origin of the term comes from Tuya Butte , which
18795-585: The future. In an article justifying the re-classification of Alaska's Mount Edgecumbe volcano from "dormant" to "active", volcanologists at the Alaska Volcano Observatory pointed out that the term "dormant" in reference to volcanoes has been deprecated over the past few decades and that "[t]he term "dormant volcano" is so little used and undefined in modern volcanology that the Encyclopedia of Volcanoes (2000) does not contain it in
18974-399: The garden. Wonderful tropical and Mediterranean plants were planted and some have now reached amazing proportions. The gardens include wonderful views over the city and harbour of Forio. A museum dedicated to the life and work of William Walton now comprises part of the garden complex. There's also a recital room where renowned musical artists perform on a regular schedule. Villa La Colombaia
19153-427: The gift of royalty from Constantine the Great, and put emphasis on his "Hellenic" descent, exalting the wisdom of the Greek people. After the Byzantines recaptured Constantinople, however, in 1261, Rhomaioi became again dominant as a term for self-description and there are few traces of Hellene (Έλληνας), such as in the writings of George Gemistos Plethon , who abandoned Christianity and in whose writings culminated
19332-466: The glossaries or index", however the USGS still widely employs the term. Previously a volcano was often considered to be extinct if there were no written records of its activity. Such a generalization is inconsistent with observation and deeper study, as has occurred recently with the unexpected eruption of the Chaitén volcano in 2008. Modern volcanic activity monitoring techniques, and improvements in
19511-573: The half century and more leading to the outbreak of the Greek War of Independence in 1821. Not coincidentally, on the eve of 1821, the three most important centres of Greek learning were situated in Chios , Smyrna and Aivali , all three major centres of Greek commerce. Greek success was also favoured by Greek domination in the leadership of the Eastern Orthodox church. The movement of
19690-484: The idea of a common Hellenism among the Greek tribes was first translated into a shared cultural experience and Hellenism was primarily a matter of common culture. The works of Homer (i.e. Iliad and Odyssey ) and Hesiod (i.e. Theogony ) were written in the 8th century BC, becoming the basis of the national religion, ethos, history and mythology. The Oracle of Apollo at Delphi was established in this period. The classical period of Greek civilization covers
19869-492: The interior of a continent and lead to rifting. Early stages of rifting are characterized by flood basalts and may progress to the point where a tectonic plate is completely split. A divergent plate boundary then develops between the two halves of the split plate. However, rifting often fails to completely split the continental lithosphere (such as in an aulacogen ), and failed rifts are characterized by volcanoes that erupt unusual alkali lava or carbonatites . Examples include
20048-485: The island actually was, like Gibraltar , home to a population of monkeys, they were already extinct by historical times as no record of them is mentioned in ancient sources. An acropolis site of the Monte Vico area was inhabited from the Bronze Age , as Mycenaean and Iron Age pottery findings attest. Euboean Greeks from Eretria and Chalcis arrived in the 8th century BC to establish an emporium for trade with
20227-487: The island in 474 BC, by Hiero I of Syracuse . At the same time, two towers were built to control enemy fleets' movements. The rock was then occupied by Parthenopeans (the ancient inhabitants of Naples ). In 326 BC the fortress was captured by Romans , and then again by the Parthenopeans. In 1441 Alfonso V of Aragon connected the rock to the island with a stone bridge instead of the prior wood bridge, and fortified
20406-467: The island is approximately 18 nautical miles from Naples , 10 km wide from east to west, 7 km from north to south, with a coastline of 43 km and an area of approximately 46.3 km. The highest elevation is Monte Epomeo , standing at 788 meters and located in the center of the island. This is an horst, a tectonic volcano, meaning a block of the Earth's crust that has been uplifted compared to
20585-701: The island to Naples in exchange for Capri . Ischia suffered from the barbarian invasions, being taken first by the Heruli then by the Ostrogoths , being ultimately absorbed into the Eastern Roman Empire . The Byzantines gave the island over to Naples in 588 and by 661 it was being administered by a Count liege to the Duke of Naples . The area was devastated by the Saracens in 813 and 847; in 1004 it
20764-490: The island's wine production . Vineyards planted within the 179 hectares (440 acres) boundaries of the DOC tend to be on volcanic soils with high pumice , phosphorus and potassium content. The white wines of the island are composed primarily of Forastera (at least 65% according to DOC regulation) and Biancolella (up to 20%) with up to 15% of other local grape varieties such as Arilla and San Lunardo . Grapes are limited to
20943-652: The island. It is accessed through a tunnel with large openings which let the light enter. Along the tunnel there is a small chapel consecrated to Saint John Joseph of the Cross (San Giovan Giuseppe della Croce), the patron saint of the island. A more comfortable access is also possible with a modern lift. After arriving outside, it is possible to visit the Church of the Immacolata and the Cathedral of Assunta . The first
21122-408: The large scale civil war between the two most powerful Greek city-states Athens and Sparta and their allies , left both greatly weakened. Most of the feuding Greek city-states were, in some scholars' opinions, united by force under the banner of Philip 's and Alexander the Great 's Pan-Hellenic ideals, though others might generally opt, rather, for an explanation of " Macedonian conquest for
21301-474: The last one occurred in 1302 in the eastern sector of the island with a brief flow (known as Arso) reaching the sea. The Greeks called their colony on the island Pithekoussai (Πιθηκοῦσσαι), from which the Latin name Pithecusa was derived. The name has an uncertain etymology . According to Ovid (Metamorphoses 14.92) and the Alexandrian historian Senagora, the name would derive from pithekos, monkey, and refer to
21480-466: The later years of the Eastern Roman Empire, areas such as Ionia and Constantinople experienced a Hellenic revival in language, philosophy, and literature and on classical models of thought and scholarship. This revival provided a powerful impetus to the sense of cultural affinity with ancient Greece and its classical heritage. Throughout their history, the Greeks have retained their language and alphabet , certain values and cultural traditions, customs,
21659-720: The local Greek community, notably with the aid of the Ralli or Vagliano Brothers . With economic success, the Diaspora expanded further across the Levant , North Africa, India and the USA. In the 20th century, many Greeks left their traditional homelands for economic reasons resulting in large migrations from Greece and Cyprus to the United States , Great Britain , Australia , Canada , Germany , and South Africa , especially after
21838-419: The mid-oceanic ridge is above sea level, volcanic islands are formed, such as Iceland . Subduction zones are places where two plates, usually an oceanic plate and a continental plate, collide. The oceanic plate subducts (dives beneath the continental plate), forming a deep ocean trench just offshore. In a process called flux melting , water released from the subducting plate lowers the melting temperature of
22017-435: The mode of self-identification of the subjects of a multi-ethnic empire at least up to the 12th century, where the average subject identified as Roman; a perennialist approach, which views Romanity as the medieval expression of a continuously existing Greek nation; while a third view considers the eastern Roman identity as a pre-modern national identity. The Byzantine Greeks' essential values were drawn from both Christianity and
22196-551: The modelling of the factors that produce eruptions, have helped the understanding of why volcanoes may remain dormant for a long time, and then become unexpectedly active again. The potential for eruptions, and their style, depend mainly upon the state of the magma storage system under the volcano, the eruption trigger mechanism and its timescale. For example, the Yellowstone volcano has a repose/recharge period of around 700,000 years, and Toba of around 380,000 years. Vesuvius
22375-415: The most dangerous type, are very rare; four are known from the last million years , and about 60 historical VEI 8 eruptions have been identified in the geologic record over millions of years. A supervolcano can produce devastation on a continental scale, and severely cool global temperatures for many years after the eruption due to the huge volumes of sulfur and ash released into the atmosphere. Because of
22554-438: The mud volcano is actually a vent of an igneous volcano. Volcanic fissure vents are flat, linear fractures through which lava emerges. Shield volcanoes, so named for their broad, shield-like profiles, are formed by the eruption of low-viscosity lava that can flow a great distance from a vent. They generally do not explode catastrophically but are characterized by relatively gentle effusive eruptions . Since low-viscosity magma
22733-722: The myth of the Cercopes , inhabitants of the Phlegraean islands transformed by Zeus into monkeys. More plausible is the interpretation of Pliny the Elder (Nat. Hist. 111, 6.82), who instead derives the name from pythos, amphora, a theory supported by archaeological finds that testify to the Greek-Italic production of ceramics (and in particular of wine amphorae) on the island and in the Gulf of Naples. It has also been proposed that
22912-483: The name describes a characteristic of the island, rich in pine forests. "Pitueois" (rich in pines), "pituis" (pine cone), "pissa, pitta" (resin) appear as descriptive terms from which Pithekoussai could derive, meaning "island of resin ," an important substance used, among other things, to waterproof wine vessels. The name Aenaria, also used by the Latins, is linked to metallurgical workshops (from aenus, metal) located on
23091-506: The name of "Green Island". Volcanic A volcano is a rupture in the crust of a planetary-mass object , such as Earth , that allows hot lava , volcanic ash , and gases to escape from a magma chamber below the surface. The process that forms volcanoes is called volcanism . On Earth, volcanoes are most often found where tectonic plates are diverging or converging , and because most of Earth's plate boundaries are underwater, most volcanoes are found underwater. For example,
23270-452: The next. Water vapour is typically the most abundant volcanic gas, followed by carbon dioxide and sulfur dioxide . Other principal volcanic gases include hydrogen sulfide , hydrogen chloride , and hydrogen fluoride . A large number of minor and trace gases are also found in volcanic emissions, for example hydrogen , carbon monoxide , halocarbons , organic compounds, and volatile metal chlorides. The form and style of an eruption of
23449-876: The north side of the mountain. Cinder cones result from eruptions of mostly small pieces of scoria and pyroclastics (both resemble cinders, hence the name of this volcano type) that build up around the vent. These can be relatively short-lived eruptions that produce a cone-shaped hill perhaps 30 to 400 metres (100 to 1,300 ft) high. Most cinder cones erupt only once and some may be found in monogenetic volcanic fields that may include other features that form when magma comes into contact with water such as maar explosion craters and tuff rings . Cinder cones may form as flank vents on larger volcanoes, or occur on their own. Parícutin in Mexico and Sunset Crater in Arizona are examples of cinder cones. In New Mexico , Caja del Rio
23628-470: The number came to an almost complete standstill due to the currency depreciation of the ruble and COVID-19 pandemic . From Ischia, various destinations such as Naples , Vesuvius , Amalfi Coast , Capri , Herculaneum , Paestum and the neighboring island Procida can be booked. Ischia is easily reached by ferry from Naples. The number of thermal spas on the islands makes it particularly popular with tourists seeking "wellness" holidays. A regular visitor
23807-471: The number is closer to just below five million. Integration, intermarriage, and loss of the Greek language influence the self-identification of the Greek diaspora ( omogenia ). Important centres include New York City , Chicago , Boston , Los Angeles , Sydney , Melbourne , London , Toronto , Montreal , Vancouver , Auckland , and Sao Paulo . In 2010, the Hellenic Parliament introduced
23986-444: The ocean surface as new islands or floating pumice rafts . In May and June 2018, a multitude of seismic signals were detected by earthquake monitoring agencies all over the world. They took the form of unusual humming sounds, and some of the signals detected in November of that year had a duration of up to 20 minutes. An oceanographic research campaign in May 2019 showed that the previously mysterious humming noises were caused by
24165-420: The ocean surface, due to the rapid cooling effect and increased buoyancy in water (as compared to air), which often causes volcanic vents to form steep pillars on the ocean floor. Hydrothermal vents are common near these volcanoes, and some support peculiar ecosystems based on chemotrophs feeding on dissolved minerals. Over time, the formations created by submarine volcanoes may become so large that they break
24344-471: The ocean's surface. In the deep ocean basins, the tremendous weight of the water prevents the explosive release of steam and gases; however, submarine eruptions can be detected by hydrophones and by the discoloration of water because of volcanic gases . Pillow lava is a common eruptive product of submarine volcanoes and is characterized by thick sequences of discontinuous pillow-shaped masses which form underwater. Even large submarine eruptions may not disturb
24523-409: The one that destroyed the city of Saint-Pierre in Martinique in 1902. They are also steeper than shield volcanoes, with slopes of 30–35° compared to slopes of generally 5–10°, and their loose tephra are material for dangerous lahars . Large pieces of tephra are called volcanic bombs . Big bombs can measure more than 1.2 metres (4 ft) across and weigh several tons. A supervolcano is defined as
24702-425: The overlying mantle wedge, thus creating magma . This magma tends to be extremely viscous because of its high silica content, so it often does not reach the surface but cools and solidifies at depth . When it does reach the surface, however, a volcano is formed. Thus subduction zones are bordered by chains of volcanoes called volcanic arcs . Typical examples are the volcanoes in the Pacific Ring of Fire , such as
24881-475: The park are open to the public. Committees and associations work to promote tourism on the island, and provide services and activities for residents. Among these are: The sharp increase of the population between 1950 and 1980 and the growing inflow of tourists (in 2010 over 4 million tourists visited the island for at least one day) have increased the anthropic pressure on the island. Significant acreage of land previously used for agriculture has been developed for
25060-429: The place from the French flotilla . With him came his sister Costanza and through them they founded the D'Avalos dynasty which would last on the island into the 18th century. Throughout the 16th century, the island suffered the incursions of pirates and Barbary privateers from North Africa: in 1543 and 1544 Hayreddin Barbarossa laid waste to the island, taking 4,000 prisoners in the process. In 1548 and 1552, Ischia
25239-410: The place of Romiós , that was seen negatively by him. The relationship between ethnic Greek identity and Greek Orthodox religion continued after the creation of the modern Greek nation-state in 1830. According to the second article of the first Greek constitution of 1822, a Greek was defined as any native Christian resident of the Kingdom of Greece , a clause removed by 1840. A century later, when
25418-418: The plume, and new volcanoes are created where the plate advances over the plume. The Hawaiian Islands are thought to have been formed in such a manner, as has the Snake River Plain , with the Yellowstone Caldera being part of the North American plate currently above the Yellowstone hotspot . However, the mantle plume hypothesis has been questioned. Sustained upwelling of hot mantle rock can develop under
25597-439: The political heirs of imperial Rome , the descendants of their classical Greek forebears and followers of the Apostles ; during the mid-to-late Byzantine period (11th–13th century), a growing number of Byzantine Greek intellectuals deemed themselves Hellenes although for most Greek-speakers, "Hellene" still meant pagan. On the eve of the Fall of Constantinople the Last Emperor urged his soldiers to remember that they were
25776-427: The popular name of Herculaneum was "Resìna," perhaps reminiscent of an ancient market for this product, similarly to the toponym "Pizzo" in Calabria, from where the best resin, the "pece brettia" obtained from the pines of the nearby Sila, came from. Virgil poetically referred to it as Inarime and still later as Arime . Martianus Capella followed Virgil in this allusive name, which was never in common circulation:
25955-419: The religious sphere, this was a period of profound change. The spiritual revolution that took place, saw a waning of the old Greek religion, whose decline beginning in the 3rd century BC continued with the introduction of new religious movements from the East. The cults of deities like Isis and Mithra were introduced into the Greek world. Greek-speaking communities of the Hellenized East were instrumental in
26134-500: The rest of the Balkan countries, the Levant and the Black Sea states, remnants of the Old Greek Diaspora (pre-19th century). The total number of Greeks living outside Greece and Cyprus today is a contentious issue. Where census figures are available, they show around three million Greeks outside Greece and Cyprus. Estimates provided by the SAE – World Council of Hellenes Abroad put the figure at around seven million worldwide. According to George Prevelakis of Sorbonne University ,
26313-417: The rest of the island and he carved out a large gallery, both of which are still to be seen today. In 1442, he gave the island to one of his favorites, Lucretia d'Alagno , who in turn entrusted the island's governance to her brother-in-law, Giovanni Torella. Upon the death of Alfonso in 1458, they returned the island to the Angevin side. Ferdinand I of Naples ordered Alessandro Sforza to chase Torella out of
26492-421: The sake of conquest" or at least conquest for the sake of riches, glory and power and view the "ideal" as useful propaganda directed towards the city-states. In any case, Alexander's toppling of the Achaemenid Empire , after his victories at the battles of the Granicus , Issus and Gaugamela , and his advance as far as modern-day Pakistan and Tajikistan , provided an important outlet for Greek culture, via
26671-435: The same time interval. Volcanoes vary greatly in their level of activity, with individual volcanic systems having an eruption recurrence ranging from several times a year to once in tens of thousands of years. Volcanoes are informally described as erupting , active , dormant , or extinct , but the definitions of these terms are not entirely uniform among volcanologists. The level of activity of most volcanoes falls upon
26850-429: The same way; they are often described as "caldera volcanoes". Submarine volcanoes are common features of the ocean floor. Volcanic activity during the Holocene Epoch has been documented at only 119 submarine volcanoes, but there may be more than one million geologically young submarine volcanoes on the ocean floor. In shallow water, active volcanoes disclose their presence by blasting steam and rocky debris high above
27029-536: The second-class status of Christians inherent in the Ottoman millet system, according to which Muslims were explicitly awarded senior status and preferential treatment. These Greeks either emigrated, particularly to their fellow Orthodox Christian protector, the Russian Empire , or simply converted to Islam, often only very superficially and whilst remaining crypto-Christian . The most notable examples of large-scale conversion to Turkish Islam among those today defined as Greek Muslims —excluding those who had to convert as
27208-562: The secular tendency in the interest in the classical past. However, it was the combination of Orthodox Christianity with a specifically Greek identity that shaped the Greeks' notion of themselves in the empire's twilight years. In the twilight years of the Byzantine Empire, prominent Byzantine personalities proposed referring to the Byzantine Emperor as the "Emperor of the Hellenes". These largely rhetorical expressions of Hellenic identity were confined within intellectual circles, but were continued by Byzantine intellectuals who participated in
27387-622: The solidified erupted material that makes up the mantle of a volcano may be stripped away that its inner anatomy becomes apparent. Using the metaphor of biological anatomy , such a process is called "dissection". Cinder Hill , a feature of Mount Bird on Ross Island , Antarctica , is a prominent example of a dissected volcano. Volcanoes that were, on a geological timescale, recently active, such as for example Mount Kaimon in southern Kyūshū , Japan , tend to be undissected. Eruption styles are broadly divided into magmatic, phreatomagmatic, and phreatic eruptions. The intensity of explosive volcanism
27566-420: The southern shore area of the Black Sea, contemporaneous with and following the failed Greek Asia Minor Campaign , was part of this process of Turkification of the Ottoman Empire and the placement of its economy and trade, then largely in Greek hands under ethnic Turkish control. The terms used to define Greekness have varied throughout history but were never limited or completely identified with membership to
27745-505: The southern tip of the island shortly before the outbreak of the Second World War. In 1936 Ischia had a population of 30,418. Spa tourism did not start again until the early 1950s. At that time, a quite remarkable artist colony of writers, composers and visual artists lived in Forio, including Ingeborg Bachmann . Elizabeth Taylor and Luchino Visconti stayed here for filming. On August 21, 2017, Ischia had an 4.2 magnitude earthquake which killed 2 people and injured 42 more. Today, Ischia
27924-408: The spread of early Christianity in the 2nd and 3rd centuries, and Christianity's early leaders and writers (notably Saint Paul ) were generally Greek-speaking, though none were from Greece proper. However, Greece itself had a tendency to cling to paganism and was not one of the influential centers of early Christianity: in fact, some ancient Greek religious practices remained in vogue until the end of
28103-406: The surrounding areas, and initially not seismically monitored before its unanticipated and catastrophic eruption of 1991. Two other examples of volcanoes that were once thought to be extinct, before springing back into eruptive activity were the long-dormant Soufrière Hills volcano on the island of Montserrat , thought to be extinct until activity resumed in 1995 (turning its capital Plymouth into
28282-432: The surrounding crust due to magmatic pressure (horst is a German term meaning "rock"). Monte Epomeo is mistakenly thought of as a volcano, although it lacks any volcanic characteristics. Island volcanism, in fact, is particularly prevalent along the fractures that border the horst, namely Monte Epomeo. Strabo reports what the Greek historian Timeo said about a tsunami that occurred in Ischia shortly before his time. Following
28461-414: The term to the Phoenician word, and therefore Semitic i-schra, "black island." The Phoenician presence on the island is archaeologically documented from a very ancient era and, as reported by Moscati (an Italian historian), in the spread in Campania and southern Etruria, since the 8th century BC, of objects of Egyptian production or inspiration, "the Phoenician merchants settled in Ischia and then frequented
28640-434: The theory of plate tectonics. For example, some volcanoes are polygenetic with more than one period of activity during their history; other volcanoes that become extinct after erupting exactly once are monogenetic (meaning "one life") and such volcanoes are often grouped together in a geographical region. At the mid-ocean ridges , two tectonic plates diverge from one another as hot mantle rock creeps upwards beneath
28819-444: The thinned oceanic crust . The decrease of pressure in the rising mantle rock leads to adiabatic expansion and the partial melting of the rock, causing volcanism and creating new oceanic crust. Most divergent plate boundaries are at the bottom of the oceans, and so most volcanic activity on Earth is submarine, forming new seafloor . Black smokers (also known as deep sea vents) are evidence of this kind of volcanic activity. Where
28998-466: The two Byzantine Greek brothers, the monks Saints Cyril and Methodius from the port city of Thessalonica , capital of the theme of Thessalonica , who are credited today with formalizing the first Slavic alphabet . Following the Fall of Constantinople on 29 May 1453, many Greeks sought better employment and education opportunities by leaving for the West , particularly Italy , Central Europe , Germany and Russia . Greeks are greatly credited for
29177-431: The underlying ductile mantle , and most volcanic activity on Earth takes place along plate boundaries, where plates are converging (and lithosphere is being destroyed) or are diverging (and new lithosphere is being created). During the development of geological theory, certain concepts that allowed the grouping of volcanoes in time, place, structure and composition have developed that ultimately have had to be explained in
29356-420: The villages of Casamicciola Terme and Lacco Ameno . Ischia developed into a well-known artist colony at the beginning of the 20th century. Writers and painters from all over the world were attracted. Eduard Bargheer , Hans Purrmann and Arrigo Wittler lived on the island. Rudolf Levy , Werner Gilles , Max Peiffer Watenphul with Kurt Craemer and Vincent Weber stayed in the fishing village of Sant'Angelo on
29535-491: The volcanic activity of Epomeo, "...the sea receded for three stages; afterwards (...) it turned back again and its ebb tide submerged the island (...) those who lived on the mainland fled from the coast into the interior of Campania" (Geography V, 4, 9). Cumae, not far from that coast, in Greek means "wave". Volcanic activity on Ischia has generally been characterized by eruptions that were not very significant and occurred at great intervals. After eruptions in Greek and Roman times,
29714-492: The volcano. Solid particles smaller than 2 mm in diameter ( sand-sized or smaller) are called volcanic ash. Tephra and other volcaniclastics (shattered volcanic material) make up more of the volume of many volcanoes than do lava flows. Volcaniclastics may have contributed as much as a third of all sedimentation in the geologic record. The production of large volumes of tephra is characteristic of explosive volcanism. Through natural processes, mainly erosion , so much of
29893-424: The volcanoes of the East African Rift . A volcano needs a reservoir of molten magma (e.g. a magma chamber), a conduit to allow magma to rise through the crust, and a vent to allow the magma to escape above the surface as lava. The erupted volcanic material (lava and tephra) that is deposited around the vent is known as a volcanic edifice , typically a volcanic cone or mountain. The most common perception of
30072-421: The walls to defend the inhabitants against the raids of pirates . Around 1700, about 2000 families lived on the islet, including a Poor Clares convent, an abbey of Basilian monks (of the Greek Orthodox Church ), the bishop and the seminar, and the prince, with a military garrison. There were also thirteen churches. In 1912, the castle was sold to a private owner. Today the castle is the most visited monument of
30251-538: Was Angela Merkel , the former German chancellor. The island is home to the Ischia Film Festival , an international cinema competition celebrated in June or July, dedicated to all the works that have promoted the value of the local territory. In addition to the works noted above, multiple media works have been set or filmed on the island. For example: The island of Ischia is home to the eponymous Denominazione di origine controllata (DOC) that produces both red and white wines though white wines account for nearly 80% of
30430-410: Was beset by his successor Dragut Rais . With the increasing rarity and diminishing severity of the piratical attacks later in the century and the construction of better defences, the islanders began to venture out of the castle and it was then that the historic centre of the town of Ischia was begun. Even so, many inhabitants still ended up slaves to the pirates, the last known being taken in 1796. During
30609-476: Was built in 1737 on the location of a smaller chapel dedicated to Saint Francis, and closed after the suppression of convents in 1806, as well as the Poor Clares convent. The gardens, located in Forio-San Francesco, were originally the property of English composer William Walton . Walton lived in the villa next to the gardens with his Argentine wife Susana . When the composer arrived on the island in 1946, he immediately called Russell Page from England to lay out
30788-403: Was contact with barbarian (non-Greek) peoples, which was deepened in the new cosmopolitan environment of the multi-ethnic Hellenistic kingdoms. This led to a strong desire among Greeks to organize the transmission of the Hellenic paideia to the next generation. Greek science, technology and mathematics are generally considered to have reached their peak during the Hellenistic period. In
30967-421: Was described by Roman writers as having been covered with gardens and vineyards before its unexpected eruption of 79 CE , which destroyed the towns of Herculaneum and Pompeii . Accordingly, it can sometimes be difficult to distinguish between an extinct volcano and a dormant (inactive) one. Long volcano dormancy is known to decrease awareness. Pinatubo was an inconspicuous volcano, unknown to most people in
31146-416: Was discernible. The Greeks of classical antiquity idealized their Mycenaean ancestors and the Mycenaean period as a glorious era of heroes, closeness of the gods and material wealth. The Homeric Epics (i.e. Iliad and Odyssey ) were especially and generally accepted as part of the Greek past and it was not until the time of Euhemerism that scholars began to question Homer's historicity. As part of
31325-430: Was discovered in a grave on the island in 1953. Engraved upon the cup are a few lines written in the Greek alphabet . Dating from c. 730 BC, it is one of the most important testimonies to the early Greek alphabet, from which the Latin alphabet descended via the Etruscan alphabet. According to certain scholars the inscription also might be the oldest written reference to the Iliad . In 474 BC, Hiero I of Syracuse came to
31504-403: Was founded in the 8th or 9th century BCE, and known as Πιθηκοῦσαι , Pithekoūsai (Monkey Island). Roughly trapezoidal in shape, it measures approximately 10 km (6 miles) east to west and 7 km (4 miles) north to south and has about 34 km (21 miles) of coastline and a surface area of 47 square kilometres (18.1 sq mi). It is almost entirely mountainous; the highest peak
31683-404: Was occupied by Henry II of Germany ; the Norman Roger II of Sicily took it in 1130 granting the island to the Norman Aldoyn de Candida created Count d’Ischia; the island was raided by the Pisans in 1135 and 1137 and subsequently fell under the Hohenstaufen and then Angevin rule. After the Sicilian Vespers in 1282, the island rebelled, recognizing Peter III of Aragon , but was retaken by
31862-515: Was submerged after its eruption and then uplifted . Volcanism on the island has been significantly affected by tectonism that formed a series of horsts and grabens ; resurgent doming produced at least 800 m (2,600 ft) of uplift during the past 33,000 years. Many small monogenetic volcanoes formed around the uplifted block. Volcanism during the Holocene produced a series of pumiceous tephras , tuff rings , lava domes , and lava flows . The last eruption of Ischia, in 1302, produced
32041-412: Was the next period of Greek civilization, the beginnings of which are usually placed at Alexander's death. This Hellenistic age , so called because it saw the partial Hellenization of many non-Greek cultures, extending all the way into India and Bactria , both of which maintained Greek cultures and governments for centuries. The end is often placed around conquest of Egypt by Rome in 30 BC, although
