A Bilinear Source-Scaling Model for M–log A Observations of Continental Earthquakes
The Wells and Coppersmith (1994) M–log A data set for continental earthquakes (where M is moment magnitude and A is fault area) and the regression lines derived from it are widely used in seismic hazard analysis for estimating M, given A. Their relations are well determined, whether for the full data set of all mechanism types or for the subset of strike-slip earthquakes.
