In 1958, a magnitude 7.8 earthquake triggered a rockslide into Southeast Alaska’s Lituya Bay, creating a tsunami that ran 1,700 feet up a mountainside before racing out to sea. Researchers now think the region’s widespread loss of glacier ice helped set the stage for the quake. In a recently published research article, scientists with the University […]
The southern tip of the Kenai experienced a moderate earthquake at 1:23 pm on Tuesday, the earthquake generated no tsunami warnings and no damage was reported. The 4.4 quake occurred at a depth of 39 miles beneath the surface 30 miles south of Homer and was felt throughout the Kenai Peninsula. While the Tsunami Center […]
A tsunami warning was issued by the National Tsunami Warning Center in Palmer following a heavy earthquake with a preliminary magnitude assessment of 7.5 that occurred 55 miles southeast of Sandpoint at 12:55 pm on Monday afternoon. The depth of the quake was at 25 miles along the Aleutian megathrust and occurred on the […]
In May of 2020, local geologists identified a steep, unstable slope that has the potential to become a tsunami-generating landslide in Barry Arm, a glacial fjord 60 miles east of Anchorage, Alaska. With documented cases of tsunami-generating landslides in Alaska including Lituya Bay in 1958 and Taan Fjord in 2015, this new hazard immediately caught the attention of […]
