| Name | Title | Fields of interest | |
|---|---|---|---|
 | Prof. Göran Ekström | Professor | Göran Ekström's main research interest is global earthquake seismology. This includes the detailed study of individual earthquake ruptures, and the relationship between seismicity and the large scale tectonic deformation of the crust and mantle over geologic time. Prof. Ekström's teaching interests include Environmental Geology, in particular the science and policy aspects of the assessment and mitigation of Geologic Hazards. |

Dec 10, 2007--Scientists from Columbia University’s Lamont-Doherty Earth Observatory will report this week on vital topics including new evidence of the effects of climate change; technologies to confront it; studies of eastern U.S. earthquake risk; and previously unseen inner workings of the deep polar ice caps. The reports will be presented at the fall 2007 American Geophysical Union (AGU), the largest earth-sciences gathering in the world, Dec. 10-14 in San Francisco. - August 25, 2008
Indian Point Nuclear Power Plant Seen As Particular RiskA study by a group of prominent seismologists suggests that a pattern of subtle but active faults makes the risk of earthquakes to the New York City area much greater than formerly believed.

Seismologists at Columbia University and Harvard University have found a new indicator that the Earth is warming: "glacial earthquakes" caused when the rivers of ice lurch unexpectedly and produce temblors as strong as magnitude 5.1 on the moment-magnitude scale, which is similar to the Richter scale. Glacial earthquakes in Greenland, the researchers found, are most common in July and August, and have more than doubled in number since 2002.

That rumbling you feel is not necessarily a passing subway. New York City and the surrounding region gets a surprising number of small earthquakes, and a 2008 study from the region’s network of seismographs, run by Lamont-Doherty Earth Observatory, suggests that the risk of a damaging one is not negligible. This week, the federal government announced a major upgrade to that network.
