Stress drop

Stress drop

The difference between the stress across a fault before and after an earthquake. A parameter in many models of the earthquake source that has a bearing on the level of high-frequency shaking that the fault radiates. Commonly stated in units termed bars or megapascals (1 bar equals 1 kg/cm2, and 1 megapascal equals 10 bars).
