A large, 7.8 magnitude earthquake struck Nepal on Saturday 26th. It was a quite a shallow earthquake (near to the surface) which meant more of the force affected surface geology and buildings.
This is a devastatingly large earthquake for a very poor country which lacks the infrastructure to deal with major hazards such as this. This is the link to the CIA world factbook page for Nepal. Think about how the lack of hospitals and services will hamper the relief effort.
Due to the geology of the area, landslides and liquefaction may have occires. Prof Dave Petley has a very informative blog post on the quake.
Climbers and mountaineers who were on Everest looking to climb the world’s highest mountain have also been affected with at least 17 dead.
