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

Overview map and location of the landslide-generated tsunami event within Alaska (inset) and Kenai Fjords National Park. 

Seismic signals from the August 7th, 2024 tsunamigenic landslide recorded on seismic station AK.SWD, located approximately 30 km (approx. 18.6 mi) from the landslide location. Three directions of ground motion are shown. The gray line is the high-frequency filtered signal.

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.
