Abstract
The various useful source-parameter relations between seismic moment and common use magnitude lg(M0) andMs,ML,mb; between magnitudesMs andML,Ms andmb,ML andmb; and between magnitudeMs and lg(L) (fault length), lg (W) (fault width), lg(S) (fault area), lg(D) (average dislocation);ML and lg(fc) (corner frequency) have been derived from the scaling law which is based on an “average” two-dimensional faulting model of a rectangular fault. A set of source-parameters can be estimated from only one magnitude by using these relations. The average rupture velocity of the faultVr=2.65 km/s, the total time of ruptureT(s)=0.35L (km) and the average dislocation slip rateD=11.4 m/s are also obtained.
