Tectonic Setting of Northwest AlaskaA wide, diffuse zone of seismicity extends from northwest Alaska across the Bering Strait
into eastern Russia. This zone is believed to mark northern boundary of the Bering microplate.
Moderate-to-large normal faulting and strike-slip events have occurred in this region, including
on the Seward Peninsula. The largest of these events was the 1958 M7.3 Huslia earthquake. It was
a normal faulting event that produced extensive failures in unconsolidated surficial deposits
within a northeast-striking zone. In 2014, a vigorous earthquake swarm was recorded about 25 miles
north of Noatak on the Lisburne Peninsula.
