The April 2015 Nepal earthquake (also known as the Gorkha earthquake) killed more than 9,000 people and injured more than 23,000—and destroyed more than 750,000 homes. It was a magnitude 7.8 on the Richter Scale and was the worst natural disaster to strike Nepal since the Bihar earthquake in 1934.
The 2015 Gorkha earthquake triggered an avalanche on Mount Everest, killing at least 19, and in the Langtang valley, where 250 people were reported missing.
In dozens of other districts, hundreds of thousands of people were made homeless when entire villages were flattened. Centuries-old buildings were destroyed at UNESCO World Heritage sites in the Kathmandu Valley, including Kathmandu Durbar Square, Patan Durbar Square, Bhaktapur Durbar Square, the Changu Narayan Temple, and the Swayambhunath Stupa. Geophysicists and other experts had warned for decades that Nepal was vulnerable to a deadly earthquake, particularly because of its geology, urbanization, and architecture, but nothing had been done to prepare.
