1819 Rann of Kutch earthquake
The 1819 Rann of Kutch earthquake occurred at about 18:45 to 18:50 local time on 16 June. It had an estimated magnitude ranging from 7.7 to 8.2 on the moment magnitude scale and a maximum perceived intensity of XI (''Extreme'') on the Mercalli intensity scale. It triggered a tsunami and caused at least 1,543 deaths. The earthquake caused an area of subsidence to that formed the Sindri Lake and a local zone of uplift to the north about 80 km long, 6 km wide and 6 m high that dammed the Puram river. This natural dam was known as the Allah Bund ("Dam of God").
==Tectonic setting==
The Kutch District of modern-day Gujarat lies about 400 km from the plate boundary between the Indian Plate and the Eurasian Plate, but the current tectonics is still governed by the effects of the continuing continental collision along this boundary. During the break-up of Gondwana in the Jurassic, this area was affected by rifting with a roughly west-east trend. During the collision with Eurasia the area has undergone shortening, involving both reactivation of the original rift faults and development of new low-angle thrust faults. The related folding has formed a series of ranges, particularly in central Kutch. The focal mechanism of most earthquakes is consistent with reverse faulting on reactivated rift faults. The 2001 Gujarat earthquake was caused by movement on a previously unknown south-dipping fault, trending parallel to the inferred rift structures.
