A killer earthquake struck Central China

I read this news on the net today. It was so sad to know about this earthquake that Central China experienced. It killed more than 8,500 people and trapping about 900 students of their school. The earthquake has a magnitude of 7.8. Wow, it was tremendous and very strong earthquake. It sounds freaky to me. It was one of the worst quake that struck China over decades. Let's say little prayer for those people and families that are effected of this tragedy.
