A massive landslide in Alaska’s snowy Wrangell-St. Elias mountain range in July may have been caused by a summer heat wave making some slopes more vulnerable to collapse, says the Lamont-Doherty scientist who first discovered the avalanche.
Ideally, seismic stations are sited in remote, quiet locations. But other considerations are important for a good station, particularly security. As a result, we placed most of our stations in towns near schools, hospitals or town halls, where people could keep an eye on them.
Can shifting tides trigger earthquakes? Research done by Maya Tolstoy, a geophysicist at Lamont-Doherty Earth Observatory, suggests they do.
Experts discuss the rise and boom of unconventional hydrocarbon extraction in the final Sustainable Development Seminar Series of the 2012-2013 academic year.
Haiti faces ongoing pressures of high population growth, high illiteracy rates and low primary education completion rates. On April 30, the Haiti Research and Policy Program’s Dialogue Series welcomed Sophia Stranksy, CEO of the Digicel Haiti Foundation, to discuss the foundation’s primary education and youth programs and Haiti’s challenges.

Earth Institute research expeditions investigating the dynamics of the planet on all levels take place on every continent and every ocean. Most projects originate with our main research center, Lamont-Doherty Earth Observatory, and are often run in collaboration with other institutions.
The last part of our river work was on the Jamuna River, as the Brahmaputra is called south of where if diverges from its former course. It shifted up to 100 km to this course about 200 years ago. We visited Sirajganj where an embankment protects the city from the migrating river and Aricha near the confluence of the Jamuna and Ganges. We ended our journey by standing with one foot in each of these two great rivers.
We traveled to the Brahmaputra River, one of the most active on the planet, to continue our fieldwork. We visited two places while working our way downstream and saw the rapid changes in the river bank and chars (islands). At one ghat (dock) the river had eroded a mile of the coast while in the other it added a similar amount. The chars had moved, appeared, disappeared and reemerged. In this changing environment, the resilient Bangladeshi char people shifted and adapted with the land.
Haiti Dialog Series: Author Jonathan M. Katz joined the Haiti Research and Policy Program’s dialogue series to discuss his new book and two years reporting on the Haitian recovery after the devastating 2010 earthquake. Katz argues within his book that the international aid money has become a missed opportunity to address core development challenges in Haiti and that the country remains equally vulnerable today as it did prior to January 10th, 2010.
