What caused the strong 7.1-magnitude earthquake in Tibet?
A 7.1-magnitude earthquake that struck Tibet on Tuesday, killing at least 126 people, was triggered by a rupture in the Lhasa block. It's an area under significant tectonic stress and a hotspot for seismic activity due to ongoing collision of the Indian and Eurasian tectonic plates, that's been shaping the Himalayas. The Indian plate is slowly peeling apart beneath Tibet.
