EARTHQUAKES_________________________________________________
__

Mechanism of destruction:-

Vibration energy transmitted through the earth’s surface from depth. Vibration causes damage and collapse of structures, which in turn may kill and injure occupants. Vibration may also cause landslides, liquefaction, rock falls and other ground failures, damaging settlements in the vicinity. Vibration may also trigger multiple fires, industrial or transportation accidents and may trigger floods through failure of dams and other flood retaining embankments.

Parameters of severity:-

Magnitude scales (Richter, Seismic Moment) indicate the amount of energy release at the epicenter—the size of an area affected by an earthquake is roughly related to the amount of energy released. Intensity scales (Modified Mercalli, MSK) indicate severity of ground shaking at a location—severity of shaking is also related to magnitude of energy release, distance away from epicenter......
