We examined seismic-moment rates associated with the Prince William Sound and Kodiak Island asperities of the 1964 great Alaska earthquake rupture zone to determine how seismicity has varied through time and space. Our results indicate that there has been a factor of 510 decrease in seismic-moment rates within the Prince William Sound asperity region since 1964, whereas seismic-moment rates have actually increased within the Kodiak asperity region since 1964, primarily because of a sequence of Mw > 7.0 earthquakes that have occurred since 1998.
