1762 Arakan earthquake : ウィキペディア英語版 | 1762 Arakan earthquake
The 1762 Arakan earthquake occurred at about 17:00 local time on 2 April, with an epicentre somewhere on the coast from Chittagong (modern Bangladesh) to Arakan in modern Burma. It had an estimated magnitude of as high as 8.8 on the moment magnitude scale and a maximum estimated intensity of XI (''Extreme'') on the Mercalli intensity scale. It triggered a local tsunami in the Bay of Bengal and caused at least 200 deaths. The earthquake was associated with major areas of both uplift and subsidence. ==Tectonic setting== The eastern part of Bangladesh and the southwestern part of Burma lie along the highly oblique convergent boundary between the Indian Plate and the Eurasian Plate. The degree to which this deformation is partitioned into zones of thrust tectonics (accommodating that part of the motion perpendicular to the boundary) and strike-slip tectonics (accommodating the northward movement of the Indian Plate) varies along the boundary. A pure strike-slip boundary that strike parallel to the plate vector runs along the Western Burma Scarp, that is replaced to the north by the Indo-Burmese Wedge fold and thrust belt, at the western edge of the boundary zone, and a series of major dextral (right lateral) strike-slip faults, particularly the Kabaw Fault and Sagaing Fault further to the east.〔 The presence of active subduction along the eastern margin of the Bay of Bengal is disputed.
