1) Nepal sits at a tectonic plate boundary where the Indian plate is pushing under the Eurasian plate at a rate of 2 inches per year, building pressure that is relieved by earthquakes.
2) A 7.8 magnitude earthquake hit near Kathmandu on Saturday, killing over 3,800 people across various regions of Nepal, especially Sindhupalchwok and Kathmandu.
3) The earthquake was particularly deadly because Katmandu is a fast-growing city with many unreinforced buildings, and dozens of aftershocks continued to hinder rescue efforts.
