At a Melting Glacier, a Landslide, Then Tsunami, Signal Climate-Related Threat

A peculiar seismic signal was the first indication of a gigantic landslide and subsequent tsunami in the remote mountains of British Columbia. It detected what may be a growing climate-related threat.

Massive Landslide Detected in Glacier Bay’s Fragile Mountains

A 4,000-foot-high mountainside collapsed in Glacier Bay National Park this week in a massive landslide that spread debris for miles across the glacier below. Scientists at Lamont-Doherty Earth Observatory are studying it to improve understanding of landslide risks.

Summer Heat Wave May Have Triggered Landslide on Lonely Alaskan Glacier

A massive landslide in Alaska’s snowy Wrangell-St. Elias mountain range in July may have been caused by a summer heat wave making some slopes more vulnerable to collapse, says the Lamont-Doherty scientist who first discovered the avalanche.

A Library of Giant Landslides

A new method for detecting big landslides is allowing scientists to understand the dynamics of these elusive events almost instantly, without traipsing to remote mountains or scrambling up rugged peaks months, or even years, later. In a recent study in the journal Science, Göran Ekström and Colin Stark, geophysicists at Columbia University’s Lamont-Doherty Earth Observatory, have catalogued the 29 largest landslides since 1980 using satellite images and recordings from a global network of seismic instruments. A third of the avalanches are documented now for the first time.

Investigating Giant, Unseen Landslides

Steep mountains produce some of the biggest landslides on earth but in such rugged terrain who’s around to notice? These monster back country slides are now gaining attention from far-away scientists, aided by a global network of seismic stations, earth-orbiting satellites and the crowd-sourcing power of the internet.
