An earthquake struck Nepal at 11:56:54 NST on 25 April 2015 with a moment magnitude (Mw) of 7.8 or 8.1Ms 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 as a result, with most casualties reported in Nepal, including on Mount Everest, and adjoining areas of India, China, and Bangladesh.

Within minutes of the earthquake, the Government of India, via the Indian Armed Forces, initiated Operation Maitri (Operation Amity), created humanitarian missions with the primary objective of conducting relief and rescue operations in Nepal. India has been the largest aid donor to Nepal following the earthquake with a billion dollar support apart from other non-monetary reliefs extended.
