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.
