Tectonic Setting of the Alaska Peninsula
The Alaska Peninsula region experiences seismicity due to various tectonic features, including the Aleutian megathrust, which is responsible for the strongest earthquakes in the area. Notable past events include the 2020 M7.8 Simeonof Earthquake and the 2021 M8.2 Chignik Earthquake. Though these did not cause tsunamis, previous events have resulted in documented tsunamis in Russian historical records. The Wadati-Benioff Zone, where the Pacific Plate subducts beneath the North American Plate, accounts for much of the intermediate depth seismicity in this region. Various crustal seismic activities arise from local fault zones and volcanic arcs, indicative of the area’s dynamic geological landscape.
