Haiti: Physics of Quakes Past, and Future
The earthquake that struck Haiti took place along what is called a strike-slip fault—a place where tectonic plates on each side of a fault line are moving horizontally in opposite directions, like hands rubbing together. When these plates lock together, stress builds; eventually they slip; and this produces shaking. This quake was fairly shallow; it…

Witnessing the Desperation of the Poor
At the moment the Haiti earthquake struck, two Earth Institute staffers were in Port-au-Prince assessing how to make the country less poor, and less vulnerable to natural disasters. Marc Levy and Alexander Fischer of the Center for International Earth Science Information Network were working with the Haiti Regeneration Initiative, a nascent program to repair Haiti’s…

The State of the Arctic
Where climate change is concerned, the Arctic region acts as a harbinger: the extremely sensitive Arctic system reacts earlier and more profoundly to anthropogenic climate change than many other regions.

Rough seas bring unexpected rewards
Working in Antarctica is always a challenge but this trip has had more than the usual setbacks. After working feverishly in Punta Arenas to prepare our ship, we had to wait two days for some essential cargo to arrive. Not long after pushing off, we encountered rough weather in the Drake Passage, a region notorious…

Port-au-Prince and New Orleans
Extremes of nature, like hurricanes and earthquakes, can occur almost anywhere. Their effect can be anything from a nuisance–the storm that ruins the seaside vacation–to the tsunami that takes more than a quarter of a million lives and ruins the livelihoods of countless more. Human losses are the most tragic of these disasters’ many consequences,…
