Continental Breakup in East Africa
Africa is ripping apart along a 4,000 kilometer seam called the East Africa Rift, which stretches from the Red Sea to Mozambique. This huge continental tear started in the north about 25 million years ago and has been gradually unzipping to the south, with rifting in Malawi starting about 10 million years ago. Breaking up…

Scientists Respond to Earthquakes in Malawi
In December, nearly a dozen earthquakes of magnitude 5 or greater rattled the southeast African nation of Malawi, killing four, injuring hundreds, and making thousands homeless. The region had been calm for decades, so the earthquakes caught everyone by surprise. But aftershocks continue, and more quakes can be expected. Seismologists from Columbia University’s Lamont-Doherty Earth…

Rebuilding Haiti: The 10-Year Plan
The horrors of Haiti’s earthquake continue to unfold. The quake itself killed perhaps 100,000 people. The inability to organize rapid relief is killing tens of thousands more. More than 1 million people are exposed to hunger and disease and, with the rain and hurricane seasons approaching, are vulnerable to further hazards. Even an economy as…

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…

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…

Needed in Haiti: Reinforced Buildings—and Economy

What does disaster recovery mean when this happens? Poor countries suffer more from natural extremes like hurricanes, droughts and floods than do rich countries. Everything about richer countries…

Haiti: America’s ‘Teachable Moment’
President Obama is providing the leadership we need and hoped for in the face of the horror of the Haitian earthquake. The clearest evidence of American unity behind the effort to respond to the tragedy in Haiti took place at the White House on Saturday, Jan. 16, as Obama joined forces with two ex-presidents to…

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,…

How to Help Haiti Recover
President Obama has declared that the United States will not forsake Haiti in its moment of agony. Honoring this commitment would be a first for Washington. To prevent a deepening spiral of death, the United States will have to do things differently than in the past. American relief and development institutions do not function properly,…
