The Sichuan province is located in the country of China and it experiences many earthquakes with the most recent being in the year 2008 as at 2012. There are different reasons why the region experiences these earthquakes such as in 2008 it was caused by the fracture of the Longmenshan fault due to the movement of the Indo-Australian Plate and Eurasian Plate. For more information about other earthquakes that are experienced in the area you can visit sites such as wikipedia.

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.

  1. I have been in so many earthquakes. Even the littlest ones still scare me to death. You get a real sense of how little to no control you have over the world, in which we live.
