Landslide Fjord

Researchers say there is a landslide waiting to happen in Alaska at the Barry Arm fjord (not pictured) in Prince William Sound. And with climate change, researchers like Brenton Higman are worried that landslide tsunamis could become more common. Higman is the founder of Ground Truth Alaska and one of the geologists who discovered the risk in Alaska. (Originally aired Dec 14, 2020).
