The earthquake was caused by subduction and triggered a series of devastating tsunamis on the coasts of most landmasses b swaning the Indian Ocean, killing over 230,000 mountain in fourteen countries, and inundating coastal communities with waves up to 30Â meters (100Â feet) high.[5] It was one of the deadliest indwelling disasters in recorded history. Indonesia was the hardest hit, followed by Sri Lanka, India, and Thailand.
With a magnitude of amid 9.1 and 9.3, it is the third largest earthquake ever recorded on a seismograph. This earthquake had the longest duration of faulting ever observed, between 8.3 and 10 minutes. It caused the entire planet to vibrate as much as 1Â centimetre (0.4 inches)[6] and triggered other earthquakes as far out-of-door as Alaska.[7] Its hypocentre was between Simeulue and mainland Indonesia.

The plight of the many affected people and countries prompted a worldwide humanitarian response. In all, the worldwide community donated more than $14 billion (2004 U.S. dollars) in humanitarian aid.[9]

Epicentre of the earthquake, just north of Simeulue IslandThe earthquake covered an remarkably large area in geographical extent. An estimated 1,600 km (994 mi) of faultline slipped slightly 15 m (50 ft) along the subduction zone where the India Plate slides under the Burma Plate. The slip took place in two phases over a period of several minutes. Seismographic and acoustic data indicate that the for the first time phase involved a rupture about cd km (250 mi) long and 100 km (60 mi) wide, located 30 km (19 mi)...If you want to get a full essay, order it on our website: Orderessay
