huge tsunami occurred in the Karrat Fjord on the west coast of Greenland, resulting in severe property damage and casualties in the tiny fishing village of Nuugaatsiaq. The seismic energy detected prior to the tsunami was so large it was first thought to have been the result of a magnitude 4.1 earthquake. However, the cause was a massive landslide on a steep slope of the fjord where millions of cubic meters of rock plunged into the water below, 32 kilometers northeast of the village. Forty-five structures, including eleven houses, were washed away or destroyed, and four people were killed.

Alaska researchers are developing a method to detect landslide-triggered tsunamis, aiming to provide early warnings for such unpredictable events.

The rapid retreat of Barry Glacier, 28 miles northeast of Whittier, could release millions of tons of rock into Harriman Ford and generate a large tsunami in Prince William Sound, according to Alaska's top geologist.

Heavy rains and melting glaciers are making landslides in the area more common, says a geologist.

The state is seeking new support from FEMA and other partners to expand studies of landslide risks on Wrangell Island and elsewhere in Alaska.
