What caused the Nepal earthquake?


The India tectonic plate moving north at about 45mm a year is pushing under the Eurasian plate beneath the Himalayas.

Two tectonic plates meet beneath the Himalayas along a fault line. The India plate is moving north at around 45mm a year and pushing under the Eurasian plate. Over time that is how the Himalayas were created.

Dr Brian Baptie, head of seismology at the British Geological Survey in Edinburgh, explains the potential after-effects of the quake.

Saturday's catastrophic earthquake in Nepal occurred because of two converging tectonic plates: the India plate and the overriding Eurasia plate to the north, the U.S. Geological Survey said.

Tectonic plates are the large, thin, relatively rigid plates that move relative to one another on the outer surface of the Earth.
