Characteristic Earthquake Model
Characteristic Earthquake Model : A fault-specific earthquake model in which a given fault segment generates an earthquake of a size and mechanism determined from the geometry of the segment. At a specific location along a fault, the displacement (slip) is the same in successive characteristic earthquakes. Other earthquakes occurring on the fault are much smaller than these. In its application to seismic hazard analysis, it refers to an earthquake of a specific size that is known or inferred to recur at the same location, usually at a less frequent rate than that extrapolated from the frequency-magnitude relation for smaller earthquakes in the area. See: Aki (2002, p. 44-45), Grant (2002, p. 482-484), and Eq. (7.3) and Figure 15 in Ben-Zion (2003)
