102-477: The Aceh Tsunami Museum , located in Banda Aceh , Aceh , Indonesia , is a museum designed as a symbolic reminder of the 2004 Indian Ocean earthquake and tsunami disaster, as well as an educational center and an emergency disaster shelter in case the area is ever hit by a tsunami again. The Aceh Tsunami Museum was designed by Indonesian architect (and former governor of West Java ) Ridwan Kamil . The museum
204-663: A line source ). This greatly increased the geographical area over which the waves were observed, reaching as far as Mexico, Chile, and the Arctic. The raising of the seafloor significantly reduced the capacity of the Indian Ocean, producing a permanent rise in the global sea level by an estimated 0.1 mm (0.004 in). Numerous aftershocks were reported off the Andaman Islands , the Nicobar Islands and
306-466: A 2.6 m (8.5 ft) crest-to-trough tsunami was measured. As well, the tsunami was large enough to be detected in Vancouver , which puzzled many scientists, as the tsunamis measured in some parts of South America were larger than those measured in some parts of the Indian Ocean. It has been theorized that the tsunamis were focused and directed at long ranges by the mid-ocean ridges which run along
408-480: A busload of vacationers and locals to safety on higher ground. Anthropologists had initially expected the aboriginal population of the Andaman Islands to be badly affected by the tsunami and even feared the already depopulated Onge tribe could have been wiped out. Many of the aboriginal tribes evacuated and suffered fewer casualties, however. Oral traditions developed from previous earthquakes helped
510-618: A causal relationship between these events. The 2004 Indian Ocean earthquake is thought to have triggered activity in both Leuser Mountain and Mount Talang , volcanoes in Aceh along the same range of peaks, while the 2005 Nias–Simeulue earthquake sparked activity in Lake Toba , a massive caldera in Sumatra. The energy released on the Earth's surface ( M e , the energy magnitude, which
612-479: A few mosques remained standing. The greatest run-up height of the tsunami was measured at a hill between Lhoknga and Leupung , on the western coast of the northern tip of Sumatra, near Banda Aceh, and reached 51 m (167 ft). The tsunami heights in Sumatra: The island country of Sri Lanka, located about 1,700 km (1,100 mi) from Sumatra, was ravaged by the tsunami around two hours after
714-442: A landmass between them and the tsunami's location of origin are usually safe; however, tsunami waves can sometimes diffract around such landmasses. Thus, the state of Kerala was hit by the tsunami despite being on the western coast of India, and the western coast of Sri Lanka suffered substantial impacts. Distance alone was no guarantee of safety, as Somalia was hit harder than Bangladesh despite being much farther away. Because of
816-453: A large turbulent bore. Eyewitnesses described the tsunami as a "black giant", "mountain" and a "wall of water". Video footage revealed torrents of black water, surging by windows of a two-story residential area situated about 3.2 km (2.0 mi) inland. Additionally, amateur footage recorded in the middle of the city captured an approaching black surge flowing down the city streets, full of debris, inundating them. The level of destruction
918-441: A low, broad hump, barely noticeable and harmless, which generally travels at the high speed of 500 to 1,000 km/h (310 to 620 mph); in shallow water near coastlines, a tsunami slows down to only tens of kilometres per hour but, in doing so, forms large destructive waves. Scientists investigating the damage in Aceh found evidence that the wave reached a height of 24 m (80 ft) when coming ashore along large stretches of

Other aftershocks of up to magnitude 7.2 continued to shake the region daily for three or four months. As well as continuing aftershocks, the energy released by the original earthquake continued to make its presence felt well after the event. A week after
1122-447: A major earthquake under ordinary circumstances but is dwarfed by the mainshock . The shift of mass and the massive release of energy slightly altered the Earth's rotation. Weeks after the earthquake, theoretical models suggested the earthquake shortened the length of a day by 2.68 microseconds , due to a decrease in the oblateness of the Earth. It also caused the Earth to minutely "wobble" on its axis by up to 25 mm (1 in) in

Exhibitions at the museum include an electronic simulation of the 2004 Indian Ocean earthquake and tsunami , in addition to photographs of victims and exhibits featuring stories from survivors of the disaster. Adequate funding for
1326-486: A month after the earthquake found the movement to be about 0.2 m (8 in). Since movement was vertical as well as lateral, some coastal areas may have been moved to below sea level. The Andaman and Nicobar Islands appear to have shifted south-west by around 1.25 m (4 ft 1 in) and to have sunk by 1 m (3 ft 3 in). In February 2005, the Royal Navy vessel HMS Scott surveyed
1428-617: A network of sensors is needed to detect it. Tsunamis are more frequent in the Pacific Ocean than in other oceans because of earthquakes in the " Ring of Fire ". Although the extreme western edge of the Ring of Fire extends into the Indian Ocean (the point where the earthquake struck), no warning system exists in that ocean. Tsunamis there are relatively rare despite earthquakes being relatively frequent in Indonesia. The last major tsunami

The students also seen kicking the belongings of the Rohingya men, women, and children who seated on the floor and crying in fear. They burned tyres and chanting “Kick them out” and “Reject Rohingya in Aceh”. The religion of the majority of the population is Islam , with minorities including Buddhists , Christians (both Protestant and Catholic ), and Hindus . Banda Aceh
1632-423: A single block of rock some 100 m (330 ft) high and 2 km (1.2 mi) long. The momentum of the water displaced by tectonic uplift had also dragged massive slabs of rock, each weighing millions of tonnes, as far as 10 km (6 mi) across the seabed. An oceanic trench several kilometres wide was exposed in the earthquake zone. The TOPEX/Poseidon and Jason-1 satellites happened to pass over

Banda Aceh was long at the center of protracted conflicts between the Acehnese and foreign powers, including the Portuguese, the Dutch , the Japanese, and
2346-434: Is believed to have been a foreshock , preceding the main event by over two years. Great earthquakes, such as the 2004 Indian Ocean earthquake, are associated with megathrust events in subduction zones. Their seismic moments can account for a significant fraction of the global seismic moment across century-scale periods. Of all the moment released by earthquakes in the 100 years from 1906 through 2005, roughly one eighth

In many places, the waves reached as far as 2 km (1.2 mi) inland. Because the 1,600 km (1,000 mi) fault affected by the earthquake was in a nearly north–south orientation,
2754-836: Is part of the Indo-Australian plate , which underlies the Indian Ocean and Bay of Bengal , and is moving north-east at an average of 60 mm/a (0.075 in/Ms). The India Plate meets the Burma plate (which is considered a portion of the great Eurasian plate ) at the Sunda Trench . At this point, the India Plate subducts beneath the Burma plate, which carries the Nicobar Islands, the Andaman Islands, and northern Sumatra. The India Plate sinks deeper and deeper beneath

The earthquake generated a seismic oscillation of the Earth's surface of up to 200–300 mm (8–12 in), equivalent to the effect of the tidal forces caused by the Sun and Moon. The seismic waves of the earthquake were felt across the planet, as far away as the U.S. state of Oklahoma , where vertical movements of 3 mm (0.12 in) were recorded. By February 2005,
3060-410: Is the capital and largest city in the province of Aceh , Indonesia . It is located on the island of Sumatra and has an elevation of 35 meters (115 feet). The city covers an area of 61.36 square kilometers (23.69 sq mi) and had a population of 223,446 people at the 2010 Census, rising to 252,899 at the 2020 Census. The official estimate as at mid 2023 was 261,969. Banda Aceh is located on

The 2004 Indian Ocean earthquake was initially documented as having a moment magnitude of 8.8. The United States Geological Survey has its estimate of 9.1. Hiroo Kanamori of the California Institute of Technology estimates that M w 9.2
3366-621: The subduction zone where the Indian plate slides under (or subducts) the overriding Burma plate. The slip did not happen instantaneously but took place in two phases over several minutes: Seismographic and acoustic data indicate that the first phase involved a rupture about 400 km (250 mi) long and 100 km (60 mi) wide, 30 km (19 mi) beneath the sea bed—the largest rupture ever known to have been caused by an earthquake. The rupture proceeded at about 2.8 km/s (1.74 mi/s; 10,100 km/h; 6,260 mph), beginning off

The table also includes the numbers of urban villages ( gampong ) in each district, and its postal codes. Note that many suburbs of Bandar Aceh lie outside the city's official boundaries, in Aceh Besar Regency . As the capital of the Aceh province, Banda Aceh is home to many landmarks important to the history of
3570-440: The Acehnese people and the sultanates. Several festivals are held annually by the city: There are three beaches close to Banda Aceh which can be reached by car or motorcycle: Ujông Batèë Beach, Lhôk Nga Beach, and Lam Pu'uk Beach, which is the most developed of the three. Motorized becaks are common in Banda Aceh. Transport by taxis and minibuses, known as labi-labi , are also common. Since 2018, some online transportation
3672-457: The British. In 1871, the Dutch began to threaten Aceh, and on 26 March 1873, the Dutch formally declared war on Aceh. The Dutch bombarded the capital in that year and sought to capture the sultan's palace in the city to bring about a capitulation of the Acehnese. Significant support from the British in the region led the modernization and fortification of the city, and while coastal areas were lost
3774-471: The Burma plate until the increasing temperature and pressure drive volatiles out of the subducting plate. These volatiles rise into the overlying plate, causing partial melting and the formation of magma. The rising magma intrudes into the crust above and exits the Earth's crust through volcanoes in the form of a volcanic arc . The volcanic activity that results as the Indo-Australian plate subducts
3876-476: The Dutch underestimated the city's defenses. The Dutch expedition commander General Johan Köhler was killed in a skirmish around the city, leading to the failure of the first expedition . A second expedition was mounted by the Dutch within months and was successful in overwhelming the city. The Dutch moved into the capital in January 1874 believing the Acehnese to have surrendered; however, the conflict moved into

The earliest, lower amplitude signal is that of the compressional (P) wave , which takes about 22 minutes to reach the other side of the planet (the antipode ; in this case near Ecuador). The largest amplitude signals are seismic surface waves that reach
4080-518: The Eurasian plate has created the Sunda Arc . As well as the sideways movement between the plates, the 2004 Indian Ocean earthquake resulted in a rise of the seafloor by several metres, displacing an estimated 30 km (7.2 cu mi) of water and triggering devastating tsunami waves. The waves radiated outwards along the entire 1,600 km (1,000 mi) length of the rupture (acting as

4284-548: The Indonesian government . The city rose to international prominence in the aftermath of the Indian Ocean earthquake in 2004, which struck off the western coast of Sumatra. Banda Aceh was the closest major city to the earthquake's epicenter , which lay 249 kilometers (155 miles) off the coast. It suffered great damage in the earthquake and further damage when a tsunami struck shortly afterwards. Around 60,000 people in
4386-468: The Pacific Ocean. In comparison to the 2004 Indian Ocean earthquake, the death toll from these earthquakes and tsunamis was significantly lower, primarily because of the lower population density along the coasts near affected areas. Comparisons with earlier earthquakes are difficult, as earthquake strength was not measured systematically until the 1930s. However, historical earthquake strength can sometimes be estimated by examining historical descriptions of
4488-509: The aboriginal tribes escape the tsunami. For example, the folklore of the Onges talks of "huge shaking of ground followed by high wall of water". Almost all of the Onge people seemed to have survived the tsunami. The tsunami devastated the coastline of Aceh province, about 20 minutes after the earthquake. Banda Aceh , the closest major city, suffered severe casualties. The sea receded and exposed
4590-456: The antipode after about 100 minutes. The surface waves can be clearly seen to reinforce near the antipode (with the closest seismic stations in Ecuador), and to subsequently encircle the planet to return to the epicentral region after about 200 minutes. A major aftershock (magnitude 7.1) can be seen at the closest stations starting just after the 200-minute mark. The aftershock would be considered
4692-401: The capital city. The tsunami reached a run-up of 10–20 m (33–66 ft) on the western shorelines of Breueh Island and Nasi Island . Coastal villages were destroyed by the waves. On Weh Island , strong surges were experienced in the port of Sabang , yet there was little damage with reported runup values of 3–5 m (9.8–16.4 ft), most likely due to the island being sheltered from
4794-399: The city died as a result and many more were injured. The aftermath of the tsunami has seen a cessation of much of the conflict in the city and province, and domestic and international aid, as a result, has seen a major modernization and reconstruction of the city over the past decade. Banda Aceh, situated at the tip of Sumatra, has long been a strategic, transportation and trading hub in
4896-588: The city was just at the level of the second floor, and there were large amounts of debris piled along the streets and in the ground-floor storefronts. In the seaside section of Ulee Lheue, the flow depths were over 9 m (30 ft). Footage showed evidence of back-flowing of the Aceh River , carrying debris and people from destroyed villages at the coast and transporting them up to 40 km (25 mi) inland. A group of small islands: Weh, Breueh, Nasi, Teunom , Bunta , Lumpat , and Batee lie just north of

Based on the statistical data issued by the City Government of Banda Aceh, Banda Aceh had 248,727 inhabitants in May 2012, while the Indonesian national census of 2020 showed a population of 252,899. The official estimate as at mid 2023 was 261,969. On 27 December 2023, hundreds of students from various universities in Aceh , such as: Abulyatama University, Bina Bangsa Getsempena University, and University of Muhammadiyah Aceh , stormed

Like other cities with a tropical rainforest climate, Banda Aceh does not have a true dry season , with the driest month averaging 90 millimeters or 3.54 inches of precipitation. On average, the city experiences a little less than 2,000 millimeters or 79 inches of precipitation annually. Banda Aceh is divided into nine districts ( Indonesian : kecamatan ), listed below with their areas and their populations at

The 2004 Indian Ocean earthquake came just three days after a magnitude 8.1 earthquake in the sub-antarctic Auckland Islands , an uninhabited region west of New Zealand, and Macquarie Island to Australia's north. This is unusual since earthquakes of magnitude eight or more occur only about once per year on average. The U.S. Geological Survey sees no evidence of

There were no tsunami warning systems in the Indian Ocean to detect tsunamis or to warn the general population living around the ocean. Tsunami detection is difficult because while a tsunami is in deep water, it has little height and
7446-423: The minor wobble produced by the earthquake. There was 10 m (33 ft) movement laterally and 4–5 m (13–16 ft) vertically along the fault line. Early speculation was that some of the smaller islands south-west of Sumatra, which is on the Burma plate (the southern regions are on the Sunda plate ), might have moved south-west by up to 36 m (120 ft), but more accurate data released more than
7548-674: The minutes preceding a tsunami strike, the sea sometimes recedes temporarily from the coast, which was observed on the eastern earthquake rupture zone such as the coastlines of Aceh, Phuket island, and Khao Lak area in Thailand, Penang island of Malaysia, and the Andaman and Nicobar islands . This rare sight reportedly induced people, especially children, to visit the coast to investigate and collect stranded fish on as much as 2.5 km (1.6 mi) of exposed beach, with fatal results. However, not all tsunamis cause this "disappearing sea" effect. In some cases, there are no warning signs at all:
7650-623: The northwestern tip of Indonesia at the mouth of the Aceh River . Banda Aceh itself is a semi-enclave within Aceh Besar Regency , as Banda Aceh is surrounded by Aceh Besar to the south, east, and west, while it borders with the Strait of Malacca to the north. Many suburbs of the city have developed in adjacent districts of Acah Besar Regency beyond the city limits, notably to the south in Darul Imarah, Ingin Jaya and Krueng Barona Jaya Districts of
7752-575: The ongoing maintenance and use of the Aceh Tsunami Museum has not been forthcoming. The museum is one of a large number of so-called "tsunami assets", the precise legal ownership of which has been in dispute between different levels of Indonesian governments since at least 2009. As of late 2010, the Museum was only open intermittently and was poorly patronised. Banda Aceh Banda Aceh ( Acehnese : Banda Acèh , Jawi : بند اچيه )
7854-464: The parameters of the source earthquake without having to compensate for the complex ways in which proximity to the coast changes the size and shape of a wave. Before the 2004 quake there were three arguments against a large earthquake occurring in the Sumatra region. After the quake it was considered that earthquake hazard risk would need to be reassessed for regions previously thought to have low risk based on these criteria: The sudden vertical rise of
7956-556: The regency, forming part of the built-up area. The city was originally established as Bandar Aceh Darussalam Kandang and served as a capital and hub for the Sultanate of Aceh upon its foundation in the late 15th century. Later its name was changed to Bandar Aceh Darussalam , and then it became popularly known as Banda Aceh . The first part of the name comes from the Persian bandar ( بندر ) meaning "port" or "haven". The city
8058-463: The region of the original epicentre in the hours and days that followed. The magnitude 8.6 2005 Nias–Simeulue earthquake , which originated off the coast of the Sumatran island of Nias , is not considered an aftershock, despite its proximity to the epicentre, and was most likely triggered by stress changes associated with the 2004 event. The earthquake produced its own aftershocks (some registering
8160-413: The region's north and east coast were Pidie Regency , Samalanga , Panteraja , and Lhokseumawe . The high fatality rate in the area was mainly due to lack of preparation of the community towards a tsunami and limited knowledge and education among the population regarding the natural phenomenon. Helicopter surveys revealed entire settlements virtually destroyed, with destruction extending miles inland. Only
8262-646: The scientific community as the Sumatra–Andaman earthquake , was caused by a rupture along the fault between the Burma plate and the Indian plate , and reached a Mercalli intensity of IX in some areas. A massive tsunami with waves up to 30 m (100 ft) high, known as the Boxing Day Tsunami after the Boxing Day holiday, or as the Asian Tsunami , devastated communities along
8364-470: The sea will suddenly swell without retreating, surprising many people and giving them little time to flee. One of the few coastal areas to evacuate ahead of the tsunami was on the Indonesian island of Simeulue , close to the epicentre. Island folklore recounted an earthquake and tsunami in 1907 , and the islanders fled to inland hills after the initial shaking and before the tsunami struck. These tales and oral folklore from previous generations may have helped
8466-502: The seabed around the earthquake zone, which varies in depth between 1,000 and 5,000 m (550 and 2,730 fathoms; 3,300 and 16,400 ft). The survey, conducted using a high-resolution, multi-beam sonar system, revealed that the earthquake had made a considerable impact on the topography of the seabed. 1,500-metre-high (5,000 ft) thrust ridges created by previous geologic activity along the fault had collapsed, generating landslides several kilometres wide. One such landslide consisted of
8568-485: The seabed by several metres during the earthquake displaced massive volumes of water, resulting in a tsunami that struck the coasts of the Indian Ocean. A tsunami that causes damage far away from its source is sometimes called a teletsunami and is much more likely to be produced by the vertical motion of the seabed than by horizontal motion. The tsunami, like all the others, behaved differently in deep water than in shallow water. In deep ocean water, tsunami waves form only
8670-411: The seabed, prompting locals to collect stranded fish and explore the area. Local eyewitnesses described three large waves, with the first wave rising gently to the foundation of the buildings, followed minutes later by a sudden withdrawal of the sea near the port of Ulèë Lheue . This was succeeded by the appearance of two large black-coloured steep waves which then travelled inland into the capital city as
8772-514: The seafloor to pop up in seconds. This quickly elevated the height and increased the speed of waves, destroying the nearby Indonesian town of Lhoknga . Indonesia lies between the Pacific Ring of Fire along the north-eastern islands adjacent to New Guinea , and the Alpide belt that runs along the south and west from Sumatra, Java , Bali , Flores to Timor . The 2002 Sumatra earthquake
8874-475: The shallow Andaman Sea off its western coast. The tsunami was noticed as far as Struisbaai in South Africa, about 8,500 km (5,300 mi) away, where a 1.5-metre-high (5 ft) tide surged on shore about 16 hours after the earthquake. It took a relatively long time to reach Struisbaai at the southernmost point of Africa, probably because of the broad continental shelf off South Africa and because
8976-422: The shoreline, houses, except for strongly-built reinforced concrete ones with brick walls, which seemed to have been partially damaged by the earthquake before the tsunami attack, were swept away or destroyed by the tsunami. The area toward the sea was wiped clean of nearly every structure, while closer to the river, dense construction in a commercial district showed the effects of severe flooding. The flow depth at
9078-430: The surrounding coasts of the Indian Ocean, killing an estimated 227,898 people in 14 countries in one of the deadliest natural disasters in recorded history . The direct results caused major disruptions to living conditions and commerce in coastal provinces of surrounded countries, including Aceh (Indonesia), Sri Lanka , Tamil Nadu (India) and Khao Lak (Thailand). Banda Aceh reported the largest number of deaths. It
9180-446: The survival of the inhabitants. On Maikhao Beach in north Phuket City , Thailand, a 10-year-old British tourist named Tilly Smith had studied tsunamis in geography at school and recognised the warning signs of the receding ocean and frothing bubbles. She and her parents warned others on the beach, which was evacuated safely. John Chroston , a biology teacher from Scotland, also recognised the signs at Kamala Bay north of Phuket, taking
9282-535: The trading kingdom of Samudera Pasai , the then-dominant entity in northern Sumatra. However the Pasai began to collapse under pressure from declining economic conditions and the Portuguese , who occupied much of the area after occupying Malacca in the early 16th century. Sultan Ali Mughayat Syah , ruler of the newly founded Sultanate of Aceh , aggressively expanded in the area in the 1520s and established sultanate
9384-431: The tsunami as it was crossing the ocean. These satellites carry radars that measure precisely the height of the water surface; anomalies in the order of 500 mm (20 in) were measured. Measurements from these satellites may prove invaluable for the understanding of the earthquake and tsunami. Unlike data from tide gauges installed on shores, measurements obtained in the middle of the ocean can be used for computing
9486-573: The tsunami would have followed the South African coast from east to west. The tsunami also reached Antarctica, where tidal gauges at Japan's Showa Base recorded oscillations of up to a metre (3 ft 3 in), with disturbances lasting a couple of days. Some of the tsunami's energy escaped into the Pacific Ocean, where it produced small but measurable tsunamis along the western coasts of North and South America, typically around 200 to 400 mm (7.9 to 15.7 in). At Manzanillo , Mexico,
9588-518: The west coast from Moratuwa to Ambalangoda . Sri Lanka tsunami height survey: A regular passenger train operating between Maradana and Matara was derailed and overturned by the tsunami and claimed at least 1,700 lives, the largest single rail disaster death toll in history. Estimates based on the state of the shoreline and a high-water mark on a nearby building place the tsunami 7.5–9 m (25–30 ft) above sea level and 2–3 m (6 ft 7 in – 9 ft 10 in) higher than
9690-506: The western side of the province, through lesser-populated areas, to the towns of Calang , Meulaboh , and Singkil. The main bus station, Terminal Terpadu Batoh, is located at Jalan Mr. Teuku Muhammad Hasan . Banda Aceh-Sigli Toll Road, part of Trans-Sumatra Toll Road , is currently under construction; it is located at the tip of the toll road and connected with Sultan Iskandar Muda Airport. Banda Aceh has two seaports, Pelabuhan (port) Ulèë Lheuë and Pelabuhan Malahayati. Pelabuhan Ulèë Lheuë
9792-663: Was a free-of-charge transportation for passengers. Lapangan Blang Padang is a multi-use park located in the center of Banda Aceh and has become a location for citizen sports activities for decades. It has jogging track, volleyball court, football pitch, basketball court, and food courts, as well. There is a famous replica of RI 001, the first Indonesian plane, at Lapangan Blang Padang. Some other sport complexes in Banda Aceh are: Lapangan Neusu, Komplek Harapan Bangsa, Lapangan Gelanggang Unsyiah, and Lapangan Tugu In Banda Aceh, there are several indoor sport halls ( id : Gelanggang Olah Raga , abbreviated as GOR ) which previously hosted as
9894-471: Was among the hardest hit by the tsunami. The waves arrived after the sea receded about 500 m (1,600 ft), followed by an advancing small tsunami. The second and third destructive waves arrived later, which exceeded the height of the coconut trees. The inundation distance is about 5 km (3.1 mi). Other towns on Aceh's west coast hit by the disaster included Leupung , Lhokruet , Lamno , Patek, Calang , and Teunom . Affected or destroyed towns on
9996-564: Was built on the remains of the Pasai and other extinct kingdoms in the area, and made Banda Aceh the capital, naming it for himself as Kutaraja or 'City of the King'. After a long period of rule by the sultanate, Aceh began to come into conflict with the Dutch and the British in the second half of the 18th century. At the end of the 18th century, the territory of Aceh in the Malay Peninsula, namely Kedah and Pulau Pinang , were seized by
10098-418: Was caused by the 1883 eruption of Krakatoa . Not every earthquake produces large tsunamis: on 28 March 2005, a magnitude 8.7 earthquake hit roughly the same area of the Indian Ocean but did not result in a major tsunami. The first warning sign of a possible tsunami is the earthquake itself. However, tsunamis can strike thousands of kilometres away where the earthquake is felt only weakly or not at all. Also, in
10200-885: Was due to the 2004 Indian Ocean earthquake. This quake, together with the Great Alaskan earthquake (1964) and the Great Chilean earthquake (1960), account for almost half of the total moment. Since 1900, the only earthquakes recorded with a greater magnitude were the 1960 Valdivia earthquake (magnitude 9.5) and the 1964 Alaska earthquake in Prince William Sound (magnitude 9.2). The only other recorded earthquakes of magnitude 9.0 or greater were off Kamchatka , Russia, on 5 November 1952 (magnitude 9.0) and Tōhoku, Japan (magnitude 9.1) in March 2011 . Each of these megathrust earthquakes also spawned tsunamis in
10302-420: Was extreme on the northwestern areas of the city, immediately inland of the aquaculture ponds, and directly facing the Indian Ocean. The tsunami height was reduced from 12 m (39 ft) at Ulee Lheue to 6 m (20 ft) a further 8 km (5.0 mi) to the north-east. The inundation was observed to extend 3–4 km (1.9–2.5 mi) inland throughout the city. Within 2–3 km (1.2–1.9 mi) of
10404-530: Was formerly the main sea port in Aceh. It now functions as a ferry terminal. It is located in the Meuraksa area. Pelabuhan Malahayati, the current main sea port, is located in Krueng Raya, 27 km (17 mi) from Banda Aceh. It now functions as the main freight cargo terminal. Since May 2016, Banda Aceh has had a bus rapid transit system, called Trans Koetaradja . Initially, Trans Koetaradja ran only
