Alaska's Tracy Arm megatsunami: second-tallest on record signals growing glacier-driven risk
TL;DR Summary
A landslide in Tracy Arm Fjord, Alaska, dislodged 64 million cubic meters of rock and generated a megatsunami almost 500 meters high—the second-tallest ever recorded, after a 1958 Alaska event. Scientists link glacier melt from climate change to more frequent collapses, warn that such hazards may be increasing, and call for wider monitoring as cruise operators reassess safety around Alaska’s fjords.
