Retreating Glaciers Spur Alaskan Earthquakes
The study examined the likelihood of increased earthquake activity in southern Alaska as a result of rapidly melting glaciers. As glaciers melt they lighten the load on the Earth's crust. Tectonic plates, that are mobile pieces of the Earth's crust, can then move more freely.
See the difference in the Bering Glacier from October 1986 to September 2002. These images were derived from the Landsat 5 and Landsat 7 satellites.
