<br />predict either the possibility, magnitude or frequency of large <br />earthquakes. <br />Schwartz and Coppersmith (1984) introduced the concept that seismo- <br />genic faults tend to generate earthquakes of generally the same magni- <br />tude and surface rupture parameters. Between major surface faulting <br />events, a seismogenic fault zone may not produce smaller magnitude <br />events with greater frequency of occurrence. Accordingly, assessment <br />of seismic hazazd/risk should be based on geologic evaluation of fault <br />history, minimum age of movement, recurrence interval, and surface <br />rupture pazameters including tectonic slip per event and rupture length. <br />23 <br />
