Over the next seven hours, a tsunami —a series of immense ocean waves—triggered by the quake reached out across the Indian Ocean , devastating coastal areas as far away as East Africa . The Boxing Day 2004 Earthquake: A Holiday's Worst Nightmare . The earthquake was so powerful that it slowed down the earth’s speed of rotation by a tiny fraction of a second. This is an incomplete list of more recent recorded major earthquakes that have occurred within the boundaries of Indonesia—as indicated by the geology of the region, and the volcanic activity—much large numbers of earthquakes of smaller magnitude occur very regularly due to the meeting of major tectonic plates in the region. Gallery . 1797: A magnitude 8.4 earthquake near the central part of the western Sumatra generated a tsunami that flooded Padang.
The initial shock was followed by more than a dozen aftershocks. The moment magnitude of the Sumatra-Andaman earthquake may thus be larger than 9.0 by 0.1 to 0.3 units . The December 26, 2004 magnitude (M) 9.1 Sumatra-Andaman earthquake occurred along a tectonic subduction zone in which the India Plate, an oceanic plate, is being subducted beneath the Burma micro-plate, part of the larger Sunda plate. The data for the Chile and Alaska earthquakes are insufficient to determine the magnitude at very long periods. 1). On December 26, 2004, at 7:59 am local time, an undersea earthquake with a magnitude of 9.1 struck off the coast of the Indonesian island of Sumatra. A minute before 8 o'clock in the morning local time, a colossal earthquake began to shake the northern part of Sumatra and the Andaman Sea to its north.
The Sumatra-Andaman earthquake, which caused the 2004 Indian Ocean tsunami, is estimated to have released energy equivalent to 23,000 Hiroshima-type atomic bombs. This giant quake of 2004 was followed just four months later by the magnitude 8.7 quake of March 28, 2005. The magnitude 9.1 earthquake struck 30km below the surface around 160km off the western coast of northern Sumatra. National Centers for Environmental Information Statistics: 227,898 people were … Print.
Seven minutes later a stretch of the Indonesian subduction zone 1200 kilometers long had slipped by an average distance of 15 meters. The earthquake hit at just before 1am GMT or 7.58am local time on 26 December 2004. This one was west of Sumatra, under the islands of Nias and Simeulue. Although the 2005 quake was one tenth as powerful as the 2004 quake, it is still the fourth largest quake of the last 100 years, and many lives were lost. Around 8 A.M. on December 26, 2004, an earthquake of magnitude 9.1 hit northern Sumatra in Indonesia, and then shook most of the world by causing the deadliest tsunami in human history. Sumatra, Indonesia Earthquake and Tsunami, 26 December 2004 On 26 December 2004, a magnitude 9.1 earthquake (3.316 N, 95.854 E, depth 30 km) occurred off the coast of northern Sumatra, Indonesia. The day after Christmas (December 26, 2004), a large magnitude earthquake occurred just west of the island of Sumatra along a subduction boundary between two tectonic plates. Days after the 2004 Indian Ocean tsunami, a man in Banda Aceh, Indonesia, scavenged the rubble for usable items. The 2004 Indian Ocean earthquake and tsunami, also called the Sumatra-Andaman earthquake (known by the scientific community), was a great underwater earthquake.It happened at 00:58:53 UTC (07:58:53 local time) December 26, 2004..
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. In Banda Aceh, the landmass closest to the quake’s epicenter, tsunami waves topped 100 feet. More than 300 fatalities.
