Description
On Sunday, August 10th, 2025, at 13:26 UTC, a landslide occurred in Tracy Arm, Alaska, about 80 miles (130 km) south-southeast of Juneau. The landslide generated a tsunami in the fjord where a runup height reached an estimated 470 m on the opposite shore and was also recorded far from the source on a NOAA coastal tide gauge in Juneau. The National Tsunami Warning Center reported that the maximum tsunami wave height at the gauge was 36 cm (approximately 14 in) above the tide, and that the waves continued for hours.
