How much stress a fault sheds when it slips

Stress drop is the difference between the shear stress on a fault before and after it ruptures: the amount of stress released, on average, over the slipped area in an earthquake. Brune's 1970 Tectonic stress and the spectra of seismic shear waves from earthquakes related it to the seismic source spectrum, so that stress drop can be estimated from the seismic moment and the source dimension inferred from the corner frequency. The referent is the stress released per unit of a rupture, typically a few megapascals and only weakly dependent on earthquake size, and it is a core measure of how energetic a rupture is for its area.[1][2]

Unit
The released shear stress over the ruptured area, in megapascals
Recovery means
Not applicable
Measured by
Estimated from seismic moment and source radius (via corner frequency), or from slip and fault dimension in finite-source models
