A map of the United States including Hawaii, Alaska, and Puerto Rico shows landslide susceptibility from yellow (low) to red (high), where the areas without shading represent negligible potential for landslides.

Tsunami damage between the upper and lower portions of the lagoon from the landslide-generated tsunami from the 2024 Pedersen Lagoon landslide in Alaska.  It moved toward the east at the western shore and uplands of the landform between the lagoons.

Seismic signals from the August 7, 2024 Pedersen Lagoon (Alaska) tsunamigenic landslide recorded on seismic station AK.SWD, located approximately 30 km from the landslide location. Three directions of ground motion are shown. The landslide signal is followed by a long-duration, resonating signal characteristic of a seiche in the lagoon.
