Seismic MomentMo = fault length x fault width x displacement x rigidity
Moment Magnitude = Mw = log Mo/1.5 – 10.7

Distant forces cause a gradual build up of stress in the earth over tens or hundreds or thousands of years, slowly distorting the earth underneath our feet. Eventually, a pre-existing weakness in the earth--called a fault or a fault zone--can not resist the strain any longer and fails catastrophically.
