There may be several controlling earthquakes for a site. As a result of the probabalistic seismic hazard analysis (PSHA), con trolling earthquakes are characterized as mean magni tudes and distances derived from a deaggregation anal ysis of the median estimate of the PSHA. Earthquake Recurrence - Earthquake recurrence is the frequency of occurrence of earthquakes having vari ous magnitudes.
