2015 M6.8 Sutwik Island Earthquake

The Alaska Earthquake Center reported only about 50 aftershocks. The aftershock depths range between 52 and 84 km (32-52 miles). Due to sparse network coverage, only aftershocks with magnitudes 2 and above were reliably located. The largest aftershock, M4.9, occurred on May 29 at 8:40 pm AKDT (May 30 4:40 UTC).

It is common for deeper events to produce only a small number of aftershocks.
