How did earthquakes contribute to the destruction of over seventy villages in tibet?

Tibet is located in and around the Himalayan mountain range. The Himalayas were formed by the collision of two continental plates. Major earthquakes occur frequently at plate boundaries. The villages were destroyed in landslides, as most are built on slopes because flat land is hard to come by in this mountainous region. The magnitude of the earthquake and the location of the villages on slopes contributed to the destruction that occured in 2015.
