“…The magnitude distribution obeys the truncated Gutenberg‐Richter relation. Thus, the P ( m j ) can be computed by:
where M 0 and M u are the lower and upper bounds of magnitude; Δ m is the magnitude interval; β = b ln10; b is the seismicity parameters
69 . Assuming that an earthquake with a magnitude of m l occurs at a random point of ( x , y ) in m th potential source, the P [( x , y )| m l ] can be evaluated as follows:
in which
denotes the probability of an earthquake with a magnitude of m j in m th potential source; A m is the area of i th potential source.…”
