The 9.0 magnitude 2004 Indian Ocean earthquake was caused by stress in the subduction zone where the India Plate is sliding under the Burma Plate in the eastern Indian Ocean, at a rate of 6 cm/yr (2.5 in/yr). The Sunda Trench is formed along this boundary where the Indo-Australian and Eurasian Plates meet. Earthquakes in the region are either caused by thrust-faulting, where the faultline slips at right angles to the trench; or strike-slip faulting, where material to the ea ...

India Plate - 2004 Indian Ocean earthquake

The 9.0 magnitude 2004 Indian Ocean earthquake was caused by stress in the subduction zone where the India Plate is sliding under the Burma Plate in the eastern Indian Ocean, at a rate of 6 cm/yr (2.5 in/yr). The Sunda Trench is formed along this boundary where the Indo-Australian and Eurasian Plates meet. Earthquakes in the region are either caused by thrust-faulting, where the faultline slips at right angles to the trench; or strike-slip faulting, where material to the east of the faultline slips along the direction of the trench.

Like all similarly large earthquakes, the December 26, 2004 event was caused by thrust-faulting. A 100 km (60 mi) rupture caused about 1,200 km (750 mi) of the interface to slip, which moved the fault 15 m (50 ft) and lifted the sea floor several meters (yards).
