Climate Underpinnings of East Africa Drought
Watch a video interview of climate scientist Brad Lyon on the conditions leading up to the ongoing drought in East Africa. He says there’s a chance of La Niña forming later in the year, which could have devastating consequences for a region already plagued by widespread famine.

Undersea Clues to Haiti’s Earthquake History
For all of its violent destruction, the earthquake that struck Haiti on Jan. 12, 2010, hardly scratched the surface of the island. But scientists now say they have found some of the best clues to understanding the quake under water.

Collecting Data Offshore Alaska, But Just Barely
One of the core objectives of our project is to image the part of the plate tectonic boundary that locks up and then ruptures to produce great earthquakes. To examine deep parts of the interface between the Pacific plate and the North American plate in the Aleutian subduction zone, we need to go as close…

Lurking Under Bangladesh: The Next Great Earthquake?
Beneath Bangladesh: The Next Great Earthquake? from Earth Institute on Vimeo. After the recent great quakes that have swept away entire coastlines and cities in Japan, Haiti and Sumatra, scientists are now looking hard at the nation that may suffer the gravest threat of all: Bangladesh. A new documentary from the Earth Institute follows seismologists as they trace signs of…

Mapping the Alaska Megathrust
Two tectonic plates converge along a 2,500-kilometer-long subduction zone offshore southern Alaska. Stress builds up at the contact between these plates, which is released in large, destructive earthquakes like the recent event offshore Japan. One of the big conundrums about these settings is how large of an area locks up on the contact between these…
