The 1993 Latur earthquake struck India at 3:56 am local time (UTC+05:30) on 30 September. The main area affected is the districts of Latur and Osmanabad, including the Ausa block of Latur and Omerga of Osmanabad in Maharashtra, Western India.[7] Fifty-two villages were demolished in the intraplate earthquake. It measured 6.2 on the moment magnitude scale, and approximately 10,000 people died,[8] whilst another 30,000 were injured. The earthquake's hypocenter was around 10 km deep – relatively shallow – allowing shock waves to cause more damage. It is considered the deadliest earthquake in the stable continental crust to have occurred in recorded history.[4]

Because the location does not lie on a plate boundary, there was some debate as to what caused the earthquake. The Indian sub-continent crumples as it pushes against Asia and pressure is released. It is possible that this pressure is released along fault lines. Another argument is that reservoir construction along the Terna was responsible for increasing pressure on fault lines. Killari,[9] where the epicenter of the quake is believed to have been, had a large crater, which remains in place to date.[10][11]
