Detailed Description

Geologists climb a slope above Larsen Bay, Nagai Island, Alaska. Geologists studying coastal evidence of past Alaska-Aleutian subduction zone earthquakes and high tsunamis climb a slope above Larsen Bay on Nagai Island in the Shumagin seismic gap, Alaska. Findings from their surveys suggest that great earthquakes and tsunamis may be rare events in the Shumagin Islands where satellite geodesy shows that the subduction zone is presently creeping. Read more at https://doi.org/10.1029/2022EO220464.
