Of these various causes tectonic-related earthquakes are the largest and most important. These are caused by the fracture and sliding of rock along faults within the Earth s crust. A fault is a zone of the earth s crust within which the two sides have moved faults may be hundreds of miles long from 1 to over 100 miles deep and not readily apparent on the ground surface. Earthquakes initiate a number of phenomena or agents termed seismic hazards which can cause significant damage to the built environment these include fault rupture vibratory ground motion . shaking inundation . tsunami seiche dam failure various kinds of permanent ground failure . liquefaction fire or hazardous materials release. For a given earthquake any particular hazard can dominate and historically each has caused major damage and great loss of life in specific earthquakes. The expected damage given a specified value of a hazard parameter is termed vulnerability and the product of the hazard and the vulnerability . the expected damage is
