The April 2015 Nepal earthquake killed nearly 9,000 people and injured nearly 22,000. It occurred at 11:56 Nepal Standard Time on 25 April 2015, with a magnitude of 7.8Mw or 8.1Mₛ and a maximum Mercalli Intensity of VIII. Its epicenter was east of Gorkha District at Barpak, Gorkha, and its hypocenter was at a depth of approximately 8.2 km. It was the worst natural disaster to strike Nepal since the 1934 Nepal–Bihar earthquake. The ground motion recorded in the capital of Nepal was of low frequency, which, along with its occurrence at an hour where many people in rural areas were working outdoors, decreased the loss of property and human lives.
The earthquake triggered an avalanche on Mount Everest, killing 22, making 25 April 2015 the deadliest day on the mountain in history. The earthquake triggered another huge avalanche in the Langtang valley, where 250 people were reported missing.
Hundreds of thousands of Nepalese were made homeless with entire villages flattened, across many districts of the country.
