Alaska Mega-Tsunami Raises Alarm for Cruise Ships in Glacier Fjords
A massive landslide in Alaska's Tracy Arm fjord on Aug. 10, 2025 triggered one of the tallest tsunamis ever recorded, sending water 481 meters up the fjord wall. More than 64 million cubic meters of rock collapsed near South Sawyer Glacier, generating a 100-meter breaking wave traveling over 70 meters per second. No casualties occurred due to the early morning timing, but scientists warn that glacier fjords are becoming increasingly unstable as climate change accelerates glacial retreat, posing growing risks to cruise tourism.
