South-west China lies in an area that is prone to earthquakes. An earthquake in Sichuan in 2008 killed tens of thousands of people. And in 1970, a magnitude 7.7 quake in Yunnan killed at least 15,000 people.

Yet violent earthquakes related to plate tectonics have caused terrible catastrophes -- such as the magnitude-7.7 earthquake that struck the Chinese province of Hebei in 1976 and killed as many as 800,000 people.
