Abstract

We use the relative source time function method to estimate the source properties of aftershocks of the November 2002 Denali earthquake sequence to determine if there are systematic variations in scaling relationships of these events that can be related to seismic moment, focal mechanism, event date/time and location along the fault, and bedrock type. Our results show self‐similarity over earthquakes of magnitude less than five and stress‐drop dependence on focal mechanism. Strike‐slip events appear to have larger stress drops. We observed a clear stress‐drop decrease from west to east that correlates with changes in earthquake focal mechanisms along the Denali fault.
