The key principle of plate tectonics is that the lithosphere exists as separate and distinct tectonic plates, which float on the fluid-like (visco-elastic solid) asthenosphere. The relative fluidity of the asthenosphere allows the tectonic plates to undergo motion in different directions. This map shows 15 of the largest plates. Note that the Indo-Australian Plate may be breaking apart into the Indian and Australian plates, which are shown separately on this map. (Photo credit: Wikipedia)

The Sichuan Earthquake was caused by a thrust on a Northeast – Southwest (Longmenshan) fault line, which moved the earth in two sections. Geologists believe since the quake was shallow (about 3km beneath the surface), it resulted to cause a greater effect at the epicentre, which was highly populated. It is the 21st deadliest earthquake of all time.
