Glacial Earthquakes: Using Seismic and GPS Observations to Map Changes in Glaciers and Ice Sheets Worldwide

November 12, 2014


The great ice sheets of Greenland and Antarctica are losing mass while the number of glacial earthquakes is increasing, with six times as many earthquakes occurring in recent years as in the early 1990s. Join Dr. Meredith Nettles, Associate Professor of Earth and Environmental Sciences at Columbia University, as she discusses the discovery of these peculiar earthquakes, and shows how combining earthquake data with GPS measurements from glaciers allows us to learn how the glaciers and ice sheets may be affected by changing environmental conditions.

The Annual IRIS Lecture Series is presented in collaboration with the Incorporated Research Institutions for Seismology and the Seismological Society of America.
