[43], The Ministry of Disaster Management and Human Rights (Sri Lanka) authorised an evacuation order[44] at 9:08 UTC advising people living near coastal regions to move to higher ground. Sri Lanka had the most injuries with 21,411 injuries. In 2004, a 9.1-magnitude underwater earthquake off the coast of Sumatra triggered a tsunami that killed more than 200,000 people in 14 countries. [48], Six Andaman coast provinces urged people to go to high ground and stay away from areas that could be affected. The earthquake occurred at a depth of 22.9 km (14.2 mi), which is considered relatively shallow according to the scale used by the United States Geological Survey (USGS). • A magnitude 6.8 earthquake struck Izu Islands, Japan, on January 1, at a depth of 348.5 km. Sumatra is one of the Sunda Islands of western Indonesia.It is the largest island that is fully within Indonesian territory, as well as the sixth-largest island in the world at 473,481 km 2 (182,812 mi. [27] In peninsular Malaysia, shaking was felt in Penang and Kuala Lumpur. This earthquake had an overall relatively slow rupture speed, although the speed was above the S-wave velocity in some fault segments. More information on the main shock is available here. Also felt (V) at Gunungsitoli, Nias and at Jitra, Malaysia. [15][16] The rupture may have affected the crust and the upper mantle according to the kinematic source inversion. This convergence is accommodated by a broad zone of diffuse deformation. [49] This caused criticism on the internet, although it was muted by a lèse majesté law. A tsunami alert has been lifted around much of the Indian Ocean after an 8.6-magnitude earthquake struck off the western coast of Aceh, northern Sumatra… [20] People headed for higher ground in parts of Indonesia and Malaysia. [16][18], Four people in their 60s and 70s in Banda Aceh, and a 39-year-old man in Lhokseumawe died from heart attacks or shock. The earthquake of the West Coast of Northern Sumatra was awful; it had a magnitude of 9.1. Is there any relation between the two earthquakes? The magnitude 8.6 (USGS)earthquake hitoff the west coast of northern Sumatra at 2:38 p.m. (local time) on April 11, 2012. It had a depth 30 km (18.6 m) set it by location. Send us pictures or videos of the main shock effects [37] A seismologist from the British Geological Survey[38] said that the "tearing earthquake" displaced relatively little water and was therefore unlikely to cause a significant tsunami. The 2012 Indian Ocean earthquakes were magnitude 8.6 and 8.2 Mw  undersea earthquakes that struck near the Indonesian province of Aceh on 11 April at 15:38 local time. The earthquake and the largest aftershock had a fault displacement of 21.3 m (70 ft). It has been said that the tsunami that occurred after the Sumatra earthquake was the worst tsunami to ever occur. Coastal train services were suspended. The tsunami generated by the earthquake was recorded nearly world-wide and killed more people than any other tsunami in recorded history, almost 230,000 missing and presumed dead. [12] The strike-slip nature of the earthquake meant that the movement displaced relatively little seawater and was less likely to cause a tsunami. Share your earthquake experience (I Have Felt It) with our readers. Tectonic Summary. [29] In China, the earthquake was felt in Tibet. Keywords: Buoys, earthquake, subducting slab, tide gauges, tsunami monitoring. [11][21] In Aceh, where 31,000 people were killed in the 2004 Indian Ocean earthquake and tsunami, people were reported weeping. The 2012 Sumatran earthquake, then, may prove fortuitous not just in the sense that it killed so few people (USGS puts it at at least ten, compared with over almost 250,000 after the Boxing Day tsunami) but helps fuel discussion about our understanding of seismic hazard in terms of predicting the potential size of major earthquakes and the damage they might cause. Just click on the link below : [11], After the earthquake, the Indian National Centre for Ocean Information Services (INCOIS) issued a high-level tsunami warning for the Andaman and Nicobar Islands. It was the deadliest tsunami in history. [50], Small 0.5 m (20 in) waves, within regular tide limits, were reported in the Campbell Bay area of Great Nicobar Island,[11] and 10 cm (4 in) waves were reported in Thailand. Earthquakes location distribution for the last major sequences in the Sumatra region, This map shows the different processes involved in the 2012 April 11th events (strike slip) and the. All the World news First earthquake, magnitude 8.6, occurred at 09.38 BST: The 2012 April 11th event occurred 300km South West … Title: Magnitude 9.0 - OFF THE WEST COAST OF NORTHERN SUMATRA 2004 December 26 00:58:53 UTC Preliminary Earthquake Report U.S. Geological Survey, National Earthquake Information Center World Data Center for Seismology, Denver A great earthquake occurred at 00:58:53 (UTC) on Sunday, December 26, 2004. [51][52] The Indonesian Agency for Meteorology, Climatology and Geophysics said three small tsunamis struck the Aceh coast. This type of mechanism is not likely to generate powerful tsunamis. The serpentinization of oceanic lithosphere can lead to a low friction coefficient, but the reaction is possible only up to 400–500 °C (752–932 °F), which corresponds to the depth of about 25 km (16 mi). W Coast Of Northern Sumatra has had: (M1.5 or greater) 0 earthquakes in the past 24 hours 1 earthquake in the past 7 days; 2 earthquakes in the past 30 days The earthquake was caused by a strike-slip motion. Initially, authorities feared that the initial earthquake would cause a tsunami and warnings were issued across the Indian Ocean; however, these warnings were subsequently cancelled. There were also many deaths. A single dynamic weakening mechanism which can work over the whole range of slip of this earthquake is still to be identified. The 2012 Indian Ocean earthquake is associated to the reactivation of the NNE-striking sea floor fabric. Injuries were reported in Aceh Singkil, including a child who was critically injured by a falling tree. Read Figures: Two earthquakes off west coast of northern Sumatra, Indonesia latest on ITV News. [45] Deputy Director M. D. Dayananda said that a tsunami could hit Trincomalee. The occurrence of two great earthquakes within such a … 227,898 dead. M 8.6 EARTHQUAKE - OFF THE WEST COAST OF NORTHERN SUMATRA 4/11/12. Casualties. The eart… A sequence of events with fairly wide spatial and temporal extent are clearly needed to explain many facets of seismic data. Send them by mail, MMS or upload them directly from your computer. This is rare in a single earthquake. [46] The Road Development Authority removed toll charges from the Southern Sri Lanka Distributor to aid the evacuation. A debate arose among seismologists over whether this should be considered an aftershock of the December 2004 event, or a "triggered earthquake" as it was larger than typical aftershocks but on the same fault. [39], Tsunami warnings were issued in the following countries: Indonesia, Australia, Cambodia, Malaysia, Singapore, Thailand, Myanmar, Bangladesh, India, Sri Lanka, Maldives, Pakistan, Iran, United Arab Emirates, Oman, Yemen, Somalia, Kenya, Tanzania, Seychelles, Mozambique, Mauritius, Comoros, Madagascar, South Africa and the dependencies of Diego Garcia as part of the British Indian Ocean Territories, Crozet Islands, Réunion and Kerguelen Islands. [19] The quake prompted people in Indonesia, Thailand and India to leave their homes and offices in fear of tsunamis. On the Indonesian island of Nias, off the coast of Sumatra, hundreds of buildings were destroyed by the earthquake. [15], These earthquakes have a complex rupture process. The earthquake lasted for about two minutes in total. The April 11th earthquake is the consequence of strike slip motion related to intraplate deformation in the eastern Indian oceanic plate. [11] The alerts caused panic as people fled buildings and made for high ground. However, it was not reported to be felt in places closer to the epicenter such as Yunnan and Guangxi. In a period of minutes, the faulting released elastic strains that had accumulated for centuries from ongoing subduction of the India plate beneath the overriding Burma microplate. Dec. 26, Sumatra, Indonesia: magnitude 9.0 earthquake, off the west coast of Sumatra, caused a tremendously powerful tsunami in the Indian Ocean that hit 12 Asian countries, killing more than 225,000 and leaving millions homeless. The April 11, 2012 (08:38:37 UTC), M 8.6 earthquake off the west coast of northern Sumatra, Indonesia, occurred as a result of strike-slip faulting within the oceanic lithosphere of the Indo-Australia plate, the first of two M 8+ earthquakes in this region on the same day. This is the third largest… Mw 8.6 OFF W COAST OF NORTHERN SUMATRA on April 11th 2012 at 08:38 UTC, More information on the main shock is available here, Impact of lower plate structure on upper plate deformationat the NW Sumatran convergent margin from seafloor morphology, Direct evidence of active deformation in the eastern Indian oceanic plate, Extremely thin crust in the Indian Ocean possibly resulting from Plume–Ridge Interaction, Moment tensor by GeoAzur (SCARDEC method), Nice, France, Send us pictures or videos of the main shock effects. You were on the spot and you have taken photos or videos of earthquake effects (on buildings, ground, landscape), please send us your files. A process which would eventually split the Indo-Australian Plate in two probably started 8 to 10 million years ago and is still taking place. [14] A back projection analysis of data collected by Hi-net, an observation network in Japan, found a complex pattern of four conjugate faults. 9.5 – Chile Valdivia Earthquake (1960-05-22) Valdivian Earthquake struck near the city of Valdivia in … A map of the earthquakes triggered around the globe within a week of the April 2012 earthquake off the coast of Sumatra (white star). [5][6] These were unusually strong intraplate earthquakes and the largest strike-slip earthquake ever recorded. [47] Coastal bus services were temporarily re-routed. The quake hit late on Monday off the west coast of Sumatra. There was a strong correlation between the fault rupture pattern and the distribution of the aftershocks. [9][10], The magnitude 8.6 (Mw) earthquake occurred about 610 km (379 mi) southwest of Banda Aceh, Indonesia at 08:38 UTC on 11 April 2012. Simeulue is an island of fishing villages 150 km (93 mi) off the west coast of Sumatra. The 2005 Nias–Simeulue earthquake occurred on 28 March off the west coast of northern Sumatra, Indonesia.At least 915 people were killed, mostly on the island of Nias.The event caused panic in the region, which had already been devastated by the massive tsunami triggered by the 2004 Indian Ocean earthquake, but this earthquake generated a relatively small tsunami that caused limited damage. [36] The Pacific Tsunami Warning Center said that at 10:14 UTC that a tsunami was generated and may have already caused some coastal destruction. In total about 125,000 people were injured due to the earthquake and tsunami. It was on a Sunday, December 26, 2004 at 00:58:53 and it came again at the same day but at 7:52:37. If you have experienced this earthquake, you are invited to answer the online questionnaire. [11] The earthquake was caused by a strike-slip motion. 227,898 people were killed. [31] Many aftershocks with magnitude readings between 5.0 and 6.0 were recorded for several hours after the initial earthquake which hit the west coast of northern Sumatra. Projected tsunami landfall times in GMT were: 8:38 for Indonesia, 11:38 for Sri Lanka, 14:38 for the Seychelles, 17:38 for Madagascar and 20:38 for South Africa. [41] M 7.8 - off the west coast of northern Sumatra The 2012 April 11th event occurred 300km South West of the 2004 event. Watch later. The highest was 80 cm (31 in), at Meulaboh. Many studies with body-wave and long-period surface wave analyses on the Off-the-West-coast of Northern Sumatra Earthquake of April 11, 2012, have already pointed out complexities of this event (e.g., Meng et al., 2012). It was felt as far away as Malaysia, the Maldives and in India. In Decembre 2004, a M9.3 earthquake caused a devastating tsunami which killed 230,000 people in more than a dozen countries. Navy warships were put on high alert. [32][33] Since the initial magnitude 8.6 earthquake, there have been 111 aftershocks over magnitude 4.0 according to USGS, including a magnitude 6.2 on 15 April 2012. The Indian Air Force dispatched two C-130s and one Il-76 aircraft to the Andaman islands. The rupture of these earthquakes occurred on multiple, almost orthogonal faults. Areas subject to warnings included Tamil Nadu, Andhra Pradesh and the Union Territory of Andaman and Nicobar Islands. Since 2006 there have been three other earthquakes in the area with a similar faulting style. The d… A significant aftershock of magnitude Mw 8.1 occurred at 10:43 UTC, 2 hours after the main quake and was also largely felt. At least 2 people killed, 8 others died from heart attacks, 12 injured and some buildings damaged in Aceh. [11], As part of a risk mitigation measure, the Ceylon Electricity Board disconnected power supplies to coastal areas and railway control rooms. Phuket International Airport was closed. The initial quake was not expected to affect Sri Lanka, but aftershocks were being monitored. Felt in much of Sumatra and Java. The magnitude 8.1 event has been located OFF THE WEST COAST OF NORTHERN SUMATRA. [13], Both the initial earthquake and the magnitude 8.2 aftershock were classified (based on their focal mechanisms) as strike-slip earthquakes, meaning that the crust on either side shifted against each other horizontally, rather than vertically. [11], In Kolkata, underground Metro Railways services were stopped and tall office buildings and shopping malls were evacuated. It has been largely felt in the region and as far as Singapore, Thaïland and India, leading to evacuation of the population. [citation needed], During the initial earthquake and for more than two hours after none of Thailand's free television stations reported the earthquake or tsunami warnings, preferring to continue a live broadcast of a royal family ceremony, despite the National Broadcasting and Telecommunications Commission (NBTC)'s urgent order directing the emergency information to be broadcast instead without delay. [53] After the sea was seen receding about 10 metres (33 ft) at Simeulue, a 1 m (3 ft) wave was observed. http://www.facebook.com/thetrieyehttp://www.thetrieye.orghttp://gplus.to/TheTrieye It was felt as far away as Malaysia, the Maldives and in India.

[22] Some people used cars and motorcycles to reach higher ground. All these earthquakes were consistent with either left-lateral slip on SSW–NNE orientated strike-slip faults, or right-lateral slip on WNW–ESE orientated strike-slip faults, both compatible with the direction of convergence. A great earthquake occurred at 00:58:55 (UTC) on Sunday, December 26, 2004. Click on the "I Felt It" button behind the corresponding earthquake.Your earthquake experience is not only important for science, but also for people in the area as well as our global readership. [42] Prabkhakar Rao of the disaster control room in Port Blair said that there could be tsunamis as high as 1.5 m (4.9 ft) at Port Blair and 3.9 m (12.8 ft) at Campbell Bay. An earthquake of magnitude Mw 8.6 occurred off coast of the Sumatra Island (Indonesia), April 11th 2012 at 08:38 UTC (15:38 Indonesian time). The devastating M 9.1 earthquake off the west coast of northern Sumatra on December 26, 2004, occurred as the result of thrust faulting on the interface of the India plate and the Burma microplate. [8] However, there is a relative movement between the Indian Plate and the Australian Plate. The magnitude 8.6 (Mw) earthquake occurred about 610 km (379 mi) southwest of Banda Aceh, Indonesia at 08:38 UTC on 11 April 2012. [24][25][26] The quake was felt across the eastern coast of India including Chennai, Bangalore, Kochi, Bhubaneswar, Vizag and Kolkata.

[43], The Ministry of Disaster Management and Human Rights (Sri Lanka) authorised an evacuation order[44] at 9:08 UTC advising people living near coastal regions to move to higher ground. Sri Lanka had the most injuries with 21,411 injuries. In 2004, a 9.1-magnitude underwater earthquake off the coast of Sumatra triggered a tsunami that killed more than 200,000 people in 14 countries. [48], Six Andaman coast provinces urged people to go to high ground and stay away from areas that could be affected. The earthquake occurred at a depth of 22.9 km (14.2 mi), which is considered relatively shallow according to the scale used by the United States Geological Survey (USGS). • A magnitude 6.8 earthquake struck Izu Islands, Japan, on January 1, at a depth of 348.5 km. Sumatra is one of the Sunda Islands of western Indonesia.It is the largest island that is fully within Indonesian territory, as well as the sixth-largest island in the world at 473,481 km 2 (182,812 mi. [27] In peninsular Malaysia, shaking was felt in Penang and Kuala Lumpur. This earthquake had an overall relatively slow rupture speed, although the speed was above the S-wave velocity in some fault segments. More information on the main shock is available here. Also felt (V) at Gunungsitoli, Nias and at Jitra, Malaysia. [15][16] The rupture may have affected the crust and the upper mantle according to the kinematic source inversion. This convergence is accommodated by a broad zone of diffuse deformation. [49] This caused criticism on the internet, although it was muted by a lèse majesté law. A tsunami alert has been lifted around much of the Indian Ocean after an 8.6-magnitude earthquake struck off the western coast of Aceh, northern Sumatra… [20] People headed for higher ground in parts of Indonesia and Malaysia. [16][18], Four people in their 60s and 70s in Banda Aceh, and a 39-year-old man in Lhokseumawe died from heart attacks or shock. The earthquake of the West Coast of Northern Sumatra was awful; it had a magnitude of 9.1. Is there any relation between the two earthquakes? The magnitude 8.6 (USGS)earthquake hitoff the west coast of northern Sumatra at 2:38 p.m. (local time) on April 11, 2012. It had a depth 30 km (18.6 m) set it by location. Send us pictures or videos of the main shock effects [37] A seismologist from the British Geological Survey[38] said that the "tearing earthquake" displaced relatively little water and was therefore unlikely to cause a significant tsunami. The 2012 Indian Ocean earthquakes were magnitude 8.6 and 8.2 Mw  undersea earthquakes that struck near the Indonesian province of Aceh on 11 April at 15:38 local time. The earthquake and the largest aftershock had a fault displacement of 21.3 m (70 ft). It has been said that the tsunami that occurred after the Sumatra earthquake was the worst tsunami to ever occur. Coastal train services were suspended. The tsunami generated by the earthquake was recorded nearly world-wide and killed more people than any other tsunami in recorded history, almost 230,000 missing and presumed dead. [12] The strike-slip nature of the earthquake meant that the movement displaced relatively little seawater and was less likely to cause a tsunami. Share your earthquake experience (I Have Felt It) with our readers. Tectonic Summary. [29] In China, the earthquake was felt in Tibet. Keywords: Buoys, earthquake, subducting slab, tide gauges, tsunami monitoring. [11][21] In Aceh, where 31,000 people were killed in the 2004 Indian Ocean earthquake and tsunami, people were reported weeping. The 2012 Sumatran earthquake, then, may prove fortuitous not just in the sense that it killed so few people (USGS puts it at at least ten, compared with over almost 250,000 after the Boxing Day tsunami) but helps fuel discussion about our understanding of seismic hazard in terms of predicting the potential size of major earthquakes and the damage they might cause. Just click on the link below : [11], After the earthquake, the Indian National Centre for Ocean Information Services (INCOIS) issued a high-level tsunami warning for the Andaman and Nicobar Islands. It was the deadliest tsunami in history. [50], Small 0.5 m (20 in) waves, within regular tide limits, were reported in the Campbell Bay area of Great Nicobar Island,[11] and 10 cm (4 in) waves were reported in Thailand. Earthquakes location distribution for the last major sequences in the Sumatra region, This map shows the different processes involved in the 2012 April 11th events (strike slip) and the. All the World news First earthquake, magnitude 8.6, occurred at 09.38 BST: The 2012 April 11th event occurred 300km South West … Title: Magnitude 9.0 - OFF THE WEST COAST OF NORTHERN SUMATRA 2004 December 26 00:58:53 UTC Preliminary Earthquake Report U.S. Geological Survey, National Earthquake Information Center World Data Center for Seismology, Denver A great earthquake occurred at 00:58:53 (UTC) on Sunday, December 26, 2004. [51][52] The Indonesian Agency for Meteorology, Climatology and Geophysics said three small tsunamis struck the Aceh coast. This type of mechanism is not likely to generate powerful tsunamis. The serpentinization of oceanic lithosphere can lead to a low friction coefficient, but the reaction is possible only up to 400–500 °C (752–932 °F), which corresponds to the depth of about 25 km (16 mi). W Coast Of Northern Sumatra has had: (M1.5 or greater) 0 earthquakes in the past 24 hours 1 earthquake in the past 7 days; 2 earthquakes in the past 30 days The earthquake was caused by a strike-slip motion. Initially, authorities feared that the initial earthquake would cause a tsunami and warnings were issued across the Indian Ocean; however, these warnings were subsequently cancelled. There were also many deaths. A single dynamic weakening mechanism which can work over the whole range of slip of this earthquake is still to be identified. The 2012 Indian Ocean earthquake is associated to the reactivation of the NNE-striking sea floor fabric. Injuries were reported in Aceh Singkil, including a child who was critically injured by a falling tree. Read Figures: Two earthquakes off west coast of northern Sumatra, Indonesia latest on ITV News. [45] Deputy Director M. D. Dayananda said that a tsunami could hit Trincomalee. The occurrence of two great earthquakes within such a … 227,898 dead.

The eart… A sequence of events with fairly wide spatial and temporal extent are clearly needed to explain many facets of seismic data. Send them by mail, MMS or upload them directly from your computer. This is rare in a single earthquake. [46] The Road Development Authority removed toll charges from the Southern Sri Lanka Distributor to aid the evacuation. A debate arose among seismologists over whether this should be considered an aftershock of the December 2004 event, or a "triggered earthquake" as it was larger than typical aftershocks but on the same fault. [39], Tsunami warnings were issued in the following countries: Indonesia, Australia, Cambodia, Malaysia, Singapore, Thailand, Myanmar, Bangladesh, India, Sri Lanka, Maldives, Pakistan, Iran, United Arab Emirates, Oman, Yemen, Somalia, Kenya, Tanzania, Seychelles, Mozambique, Mauritius, Comoros, Madagascar, South Africa and the dependencies of Diego Garcia as part of the British Indian Ocean Territories, Crozet Islands, Réunion and Kerguelen Islands. [19] The quake prompted people in Indonesia, Thailand and India to leave their homes and offices in fear of tsunamis. On the Indonesian island of Nias, off the coast of Sumatra, hundreds of buildings were destroyed by the earthquake. [15], These earthquakes have a complex rupture process. The earthquake lasted for about two minutes in total. The April 11th earthquake is the consequence of strike slip motion related to intraplate deformation in the eastern Indian oceanic plate. [11] The alerts caused panic as people fled buildings and made for high ground. However, it was not reported to be felt in places closer to the epicenter such as Yunnan and Guangxi. In a period of minutes, the faulting released elastic strains that had accumulated for centuries from ongoing subduction of the India plate beneath the overriding Burma microplate. Dec. 26, Sumatra, Indonesia: magnitude 9.0 earthquake, off the west coast of Sumatra, caused a tremendously powerful tsunami in the Indian Ocean that hit 12 Asian countries, killing more than 225,000 and leaving millions homeless. The April 11, 2012 (08:38:37 UTC), M 8.6 earthquake off the west coast of northern Sumatra, Indonesia, occurred as a result of strike-slip faulting within the oceanic lithosphere of the Indo-Australia plate, the first of two M 8+ earthquakes in this region on the same day.

A process which would eventually split the Indo-Australian Plate in two probably started 8 to 10 million years ago and is still taking place. [14] A back projection analysis of data collected by Hi-net, an observation network in Japan, found a complex pattern of four conjugate faults. 9.5 – Chile Valdivia Earthquake (1960-05-22) Valdivian Earthquake struck near the city of Valdivia in … A map of the earthquakes triggered around the globe within a week of the April 2012 earthquake off the coast of Sumatra (white star). [5][6] These were unusually strong intraplate earthquakes and the largest strike-slip earthquake ever recorded. [47] Coastal bus services were temporarily re-routed. The quake hit late on Monday off the west coast of Sumatra. There was a strong correlation between the fault rupture pattern and the distribution of the aftershocks. [9][10], The magnitude 8.6 (Mw) earthquake occurred about 610 km (379 mi) southwest of Banda Aceh, Indonesia at 08:38 UTC on 11 April 2012. Simeulue is an island of fishing villages 150 km (93 mi) off the west coast of Sumatra. The 2005 Nias–Simeulue earthquake occurred on 28 March off the west coast of northern Sumatra, Indonesia.At least 915 people were killed, mostly on the island of Nias.The event caused panic in the region, which had already been devastated by the massive tsunami triggered by the 2004 Indian Ocean earthquake, but this earthquake generated a relatively small tsunami that caused limited damage. [36] The Pacific Tsunami Warning Center said that at 10:14 UTC that a tsunami was generated and may have already caused some coastal destruction. In total about 125,000 people were injured due to the earthquake and tsunami. It was on a Sunday, December 26, 2004 at 00:58:53 and it came again at the same day but at 7:52:37. If you have experienced this earthquake, you are invited to answer the online questionnaire. [11] The earthquake was caused by a strike-slip motion. 227,898 people were killed. [31] Many aftershocks with magnitude readings between 5.0 and 6.0 were recorded for several hours after the initial earthquake which hit the west coast of northern Sumatra. Projected tsunami landfall times in GMT were: 8:38 for Indonesia, 11:38 for Sri Lanka, 14:38 for the Seychelles, 17:38 for Madagascar and 20:38 for South Africa. [41] M 7.8 - off the west coast of northern Sumatra The 2012 April 11th event occurred 300km South West of the 2004 event. Watch later. The highest was 80 cm (31 in), at Meulaboh. Many studies with body-wave and long-period surface wave analyses on the Off-the-West-coast of Northern Sumatra Earthquake of April 11, 2012, have already pointed out complexities of this event (e.g., Meng et al., 2012). It was felt as far away as Malaysia, the Maldives and in India. In Decembre 2004, a M9.3 earthquake caused a devastating tsunami which killed 230,000 people in more than a dozen countries. Navy warships were put on high alert. [32][33] Since the initial magnitude 8.6 earthquake, there have been 111 aftershocks over magnitude 4.0 according to USGS, including a magnitude 6.2 on 15 April 2012. The Indian Air Force dispatched two C-130s and one Il-76 aircraft to the Andaman islands. The rupture of these earthquakes occurred on multiple, almost orthogonal faults. Areas subject to warnings included Tamil Nadu, Andhra Pradesh and the Union Territory of Andaman and Nicobar Islands. Since 2006 there have been three other earthquakes in the area with a similar faulting style. The d… A significant aftershock of magnitude Mw 8.1 occurred at 10:43 UTC, 2 hours after the main quake and was also largely felt. At least 2 people killed, 8 others died from heart attacks, 12 injured and some buildings damaged in Aceh. [11], As part of a risk mitigation measure, the Ceylon Electricity Board disconnected power supplies to coastal areas and railway control rooms. Phuket International Airport was closed. The initial quake was not expected to affect Sri Lanka, but aftershocks were being monitored. Felt in much of Sumatra and Java. The magnitude 8.1 event has been located OFF THE WEST COAST OF NORTHERN SUMATRA. [13], Both the initial earthquake and the magnitude 8.2 aftershock were classified (based on their focal mechanisms) as strike-slip earthquakes, meaning that the crust on either side shifted against each other horizontally, rather than vertically. [11], In Kolkata, underground Metro Railways services were stopped and tall office buildings and shopping malls were evacuated. It has been largely felt in the region and as far as Singapore, Thaïland and India, leading to evacuation of the population. [citation needed], During the initial earthquake and for more than two hours after none of Thailand's free television stations reported the earthquake or tsunami warnings, preferring to continue a live broadcast of a royal family ceremony, despite the National Broadcasting and Telecommunications Commission (NBTC)'s urgent order directing the emergency information to be broadcast instead without delay. [53] After the sea was seen receding about 10 metres (33 ft) at Simeulue, a 1 m (3 ft) wave was observed. http://www.facebook.com/thetrieyehttp://www.thetrieye.orghttp://gplus.to/TheTrieye It was felt as far away as Malaysia, the Maldives and in India. The 2004 Indian Ocean earthquake and tsunami (also known as the Boxing Day Tsunami and, by the scientific community, the Sumatra–Andaman earthquake) occurred at 07:58:53 in local time ( UTC+7) on 26 December, with an epicentre off the west coast of northern Sumatra… A significant aftershock of magnitude Mw 8.1 occurred at 10:43 UTC, 2 hours after the main quake and was also largely felt. [22] Some people used cars and motorcycles to reach higher ground. All these earthquakes were consistent with either left-lateral slip on SSW–NNE orientated strike-slip faults, or right-lateral slip on WNW–ESE orientated strike-slip faults, both compatible with the direction of convergence. A great earthquake occurred at 00:58:55 (UTC) on Sunday, December 26, 2004. Click on the "I Felt It" button behind the corresponding earthquake.Your earthquake experience is not only important for science, but also for people in the area as well as our global readership. [42] Prabkhakar Rao of the disaster control room in Port Blair said that there could be tsunamis as high as 1.5 m (4.9 ft) at Port Blair and 3.9 m (12.8 ft) at Campbell Bay. An earthquake of magnitude Mw 8.6 occurred off coast of the Sumatra Island (Indonesia), April 11th 2012 at 08:38 UTC (15:38 Indonesian time). The devastating M 9.1 earthquake off the west coast of northern Sumatra on December 26, 2004, occurred as the result of thrust faulting on the interface of the India plate and the Burma microplate. [8] However, there is a relative movement between the Indian Plate and the Australian Plate. The magnitude 8.6 (Mw) earthquake occurred about 610 km (379 mi) southwest of Banda Aceh, Indonesia at 08:38 UTC on 11 April 2012. [24][25][26] The quake was felt across the eastern coast of India including Chennai, Bangalore, Kochi, Bhubaneswar, Vizag and Kolkata.

A tsunami watch was issued by PTWC for the whole Indian Ocean region but there were no report of significant tsunami waves. [30], A magnitude 8.2 aftershock struck at a depth of 16.4 kilometres (10.2 mi) about 430 km (267 mi) southwest of Banda Aceh at 10:43 UTC, two hours after the initial earthquake. [2] The quake was originally reported as a magnitude 8.9, but was later downgraded to 8.6. [50] The Television Pool of Thailand defended their actions, saying that running texts about the warnings were displayed onscreen during the broadcast. The earthquake occurred at a depth of 22.9 km (14.2 mi), which is considered relatively shallow according to the scale used by the United States Geological Survey (USGS). [28] The tremor was felt in Colombo, Sri Lanka, where people in some high-rise buildings were evacuated. The April 11, 2012, M8.6 and M8.2 earthquakes off the west coast of northern Sumatra, Indonesia, occurred as a result of strike-slip faulting within the oceanic lithosphere of the Indo-Australia plate. The quake was originally reported as a magnitude 8.9, but was later downgraded to 8.6. [40] Authorities told civilians to move away from the coast and towards higher ground. An 8.2-magnitude aftershock was reported off the coast of northern Sumatra with an epicenter 382 miles from Banda Aceh, Sumatra, Indonesia, around 6:43 a.m., according to the U.S. Geological Survey. In the twenty-four hours immediately after the event, there were eight major aftershocks, measuring between 5.5 and 6.0. If you have experienced this earthquake, you are invited to answer the online questionnaire. At their boundary, the Indian and Australian Plates converge at 11 mm (0.4 in) per year in a NNW–SSE direction. (This event has … December 26, 2004 - A magnitude 9.1 earthquake strikes off the west coast of Northern Sumatra, Indonesia. [17] The rupture was caused by ductile shear heating instability which is different from frictional failure and operates between 600–800 °C (1,112–1,472 °F), which corresponds to about the depths of 40–60 km (25–37 mi). [34][35], Three hours after the initial quake it was still unclear whether a tsunami had been generated or if a tsunami had done any significant damage.

[43], The Ministry of Disaster Management and Human Rights (Sri Lanka) authorised an evacuation order[44] at 9:08 UTC advising people living near coastal regions to move to higher ground. Sri Lanka had the most injuries with 21,411 injuries. In 2004, a 9.1-magnitude underwater earthquake off the coast of Sumatra triggered a tsunami that killed more than 200,000 people in 14 countries. [48], Six Andaman coast provinces urged people to go to high ground and stay away from areas that could be affected. The earthquake occurred at a depth of 22.9 km (14.2 mi), which is considered relatively shallow according to the scale used by the United States Geological Survey (USGS). • A magnitude 6.8 earthquake struck Izu Islands, Japan, on January 1, at a depth of 348.5 km. Sumatra is one of the Sunda Islands of western Indonesia.It is the largest island that is fully within Indonesian territory, as well as the sixth-largest island in the world at 473,481 km 2 (182,812 mi. [27] In peninsular Malaysia, shaking was felt in Penang and Kuala Lumpur. This earthquake had an overall relatively slow rupture speed, although the speed was above the S-wave velocity in some fault segments. More information on the main shock is available here. Also felt (V) at Gunungsitoli, Nias and at Jitra, Malaysia. [15][16] The rupture may have affected the crust and the upper mantle according to the kinematic source inversion. This convergence is accommodated by a broad zone of diffuse deformation. [49] This caused criticism on the internet, although it was muted by a lèse majesté law. A tsunami alert has been lifted around much of the Indian Ocean after an 8.6-magnitude earthquake struck off the western coast of Aceh, northern Sumatra… [20] People headed for higher ground in parts of Indonesia and Malaysia. [16][18], Four people in their 60s and 70s in Banda Aceh, and a 39-year-old man in Lhokseumawe died from heart attacks or shock. The earthquake of the West Coast of Northern Sumatra was awful; it had a magnitude of 9.1. Is there any relation between the two earthquakes? The magnitude 8.6 (USGS)earthquake hitoff the west coast of northern Sumatra at 2:38 p.m. (local time) on April 11, 2012. It had a depth 30 km (18.6 m) set it by location. Send us pictures or videos of the main shock effects [37] A seismologist from the British Geological Survey[38] said that the "tearing earthquake" displaced relatively little water and was therefore unlikely to cause a significant tsunami. The 2012 Indian Ocean earthquakes were magnitude 8.6 and 8.2 Mw  undersea earthquakes that struck near the Indonesian province of Aceh on 11 April at 15:38 local time. The earthquake and the largest aftershock had a fault displacement of 21.3 m (70 ft). It has been said that the tsunami that occurred after the Sumatra earthquake was the worst tsunami to ever occur. Coastal train services were suspended. The tsunami generated by the earthquake was recorded nearly world-wide and killed more people than any other tsunami in recorded history, almost 230,000 missing and presumed dead. [12] The strike-slip nature of the earthquake meant that the movement displaced relatively little seawater and was less likely to cause a tsunami. Share your earthquake experience (I Have Felt It) with our readers. Tectonic Summary. [29] In China, the earthquake was felt in Tibet. Keywords: Buoys, earthquake, subducting slab, tide gauges, tsunami monitoring. [11][21] In Aceh, where 31,000 people were killed in the 2004 Indian Ocean earthquake and tsunami, people were reported weeping. The 2012 Sumatran earthquake, then, may prove fortuitous not just in the sense that it killed so few people (USGS puts it at at least ten, compared with over almost 250,000 after the Boxing Day tsunami) but helps fuel discussion about our understanding of seismic hazard in terms of predicting the potential size of major earthquakes and the damage they might cause. Just click on the link below : [11], After the earthquake, the Indian National Centre for Ocean Information Services (INCOIS) issued a high-level tsunami warning for the Andaman and Nicobar Islands. It was the deadliest tsunami in history.

[46] The Road Development Authority removed toll charges from the Southern Sri Lanka Distributor to aid the evacuation. A debate arose among seismologists over whether this should be considered an aftershock of the December 2004 event, or a "triggered earthquake" as it was larger than typical aftershocks but on the same fault. [39], Tsunami warnings were issued in the following countries: Indonesia, Australia, Cambodia, Malaysia, Singapore, Thailand, Myanmar, Bangladesh, India, Sri Lanka, Maldives, Pakistan, Iran, United Arab Emirates, Oman, Yemen, Somalia, Kenya, Tanzania, Seychelles, Mozambique, Mauritius, Comoros, Madagascar, South Africa and the dependencies of Diego Garcia as part of the British Indian Ocean Territories, Crozet Islands, Réunion and Kerguelen Islands. [19] The quake prompted people in Indonesia, Thailand and India to leave their homes and offices in fear of tsunamis. On the Indonesian island of Nias, off the coast of Sumatra, hundreds of buildings were destroyed by the earthquake. [15], These earthquakes have a complex rupture process. The earthquake lasted for about two minutes in total. The April 11th earthquake is the consequence of strike slip motion related to intraplate deformation in the eastern Indian oceanic plate. [11] The alerts caused panic as people fled buildings and made for high ground. However, it was not reported to be felt in places closer to the epicenter such as Yunnan and Guangxi. In a period of minutes, the faulting released elastic strains that had accumulated for centuries from ongoing subduction of the India plate beneath the overriding Burma microplate.
