Answer 1

There are many fault lines in Tangshan China which are very earthquake prone.  An earthquake happens because a rock or fault cracks or fractures.  The intensity of the earthquake is measured by the damage, and severity of the fault break.  The surface waves are the slowest and most dangerous.  The surface and body waves during the Chinese earthquake was severe and the fault-line break was a big one.
