2018 M6.4 Kaktovik Earthquake

This earthquake will be extremely important for understanding North Slope seismicity and, more generally, how seismic waves travel throughout Alaska. We are very fortunate that this earthquake happened during the USArray deployment in Alaska. Before 2013, the nearest stations would have been at Pump Station 1 and Pump Station 4. Instead, we have high quality recordings from a number of research-grade stations fairly close to the source.

We received no reports of damage or injuries, and Alyeska reported no impact on pipeline operations. The earthquake was felt widely, with reports coming from Kaktovik west to Nuiqsut and as far south as Fairbanks.
