It was hit by massive avalanches of snow, rocks and mud, originating on the slopes of Huascarán and triggered by earthquakes on 10 January 1962 and on 31 May 1970. Over two thousand people from the village perished in the 1962 avalanche, along with the inhabitants of seven nearby settlements.[1] In total about 3,500 died in the disaster.[2] About 20,000 people died in the avalanches that resulted from the second earthquake (known as the 1970 Ancash earthquake).[3]400 survived from the second disaster.[4]
