An earthquake struck Nepal at 11:56:54 NST on 25 April 2015 with a moment magnitude of 7.8 and a maximum Mercalli intensity of IX (Violent). It was the most powerful earthquake to strike Nepal since the 1934 Nepal–Bihar earthquake. Many thousands of people died, with most casualties reported in Nepal, and adjoining areas of India, China,Bhutan and Bangladesh.

A major earthquake occurred in Nepal on 12 May 2015 at 12:50 pm local time with a moment magnitude of 7.3, 18 kilometres (11 mi) southeast of Kodari. The epicenter was on the border of Dolakha and Sindhupalchowk, two districts of Nepal. This earthquake occurred on the same fault as the larger magnitude 7.8 earthquake of 25 April, but further east than the original quake. As such, it is considered to be an aftershock of the April quake. It struck at a depth of 18.5 km (11.5 mi). Shaking was felt in northern parts of India including Bihar, Uttar Pradesh and West Bengal. Tremors were felt as far as about 2,400 km away from the epicenter in Chennai.
