It funds maps, sirens and education. "Losing this program, really, at the end of the day could mean deaths in Alaska," says a state official.

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

Hikers should be cautious when hiking the Castner Glacier trail since chunks of ice may fall and the streams and rivers are very fast.

Landslides and tsunamis aren’t historically common in Glacier Bay, but because more than half a million visitors tour the park each year park managers want to get a clearer picture of the risks of tsunamis and landslides, which have become more common recently due to a changing climate.

Within a set of glaciers and mountains near Juneau, there’s seismic activity almost every day in the summer. They’re called ice quakes. They’re not as widely understood as earthquakes, but researchers are monitoring them closely.

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.

A powerful wave as tall as 55-storey building crashed through a fjord in Alaska in 2015, stripping the mountainsides of trees and dirt. It was triggered by a landslide — and researchers say such tsunamis could pose an increasing risk in places like Western Canada as climate change melts glaciers.

A 300-metre wide, 1,000-meter high rock slid into the sea causing the initial wave and more of the rock face is unstable.

When 200 million metric tons of rock tumbled down a remote Southeast Alaska mountain in October, nobody was around to see it. But thanks to a beefed-up seismic network and a new system that can distinguish landslides from earthquakes, scientists knew it had happened.

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.
