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.

Fast-moving, highly destructive debris flows triggered by intense rainfall are one of the most dangerous post-fire hazards. The risk of floods and debris flows after fires increases due to vegetation loss and soil exposure. Cases of sudden and deadly debris flow are well documented along the western United States, particularly in Southern California.
