The M6.0 mainshock was preceded by less than a minute by a M5.4 foreshock that occurred in the same location. The largest aftershock was a M4.6 and occurred 3 minutes after the mainshock.

The Alaska Earthquake Center recorded about 230 aftershocks within first month after the mainshock. Only aftershocks with magnitudes 2 or larger can be detected due to sparse seismic network coverage in the region.
