The lakes along the Great African Rift Valley are among the largest fresh water lakes in the world. They lie in depressions created by slow stretching and thinning of the east African continent over millions of years. Many of the essential geological structures that enable the continent to tear and produce earthquakes are hidden within []

This week marks the launch of the new Columbia Initiative on Extreme Weather and Climate, a cross-disciplinary collaboration between a variety of centers, research groups and individuals from across Columbia University. The Initiative, led by Adam Sobel, kicked off on Monday evening with a World Leaders Forum panel event in Low Library. Panelists discussed a wide range of science and policy topics related to extreme weather, showing the interdisciplinary nature of the new Initiative.

SeismoDome

Lamont-Doherty Earth Observatory scientist Ben Holtzman grew up discovering science through interactive exhibits in San Francisco’s Exploratorium and now provides a similar experience for others. Holtzman designs immersive shows that allow people to experience what earthquakes and seismic waves look and sound like as they move through and around the Earth. On Monday, November 17th at the American Museum of Natural History Hayden Planetarium, Holtzman and his collaborators will present one of these shows, the second installment of SeismoDome: Sights and Sounds of Global Seismology.

Hydraulic fracturing, or fracking, the controversial method for extracting natural gas, has become a hot button issue across the U.S. But let’s try to look objectively at its benefits and risks.

Bricks, an Archeological Site and Home

by | 3.7.2014 at 8:33am
One of the myriad brick factories in Bangladesh.  The lack of rocks means bricks are widely used for construction.

It was time to pack up and leave. Shofiq, who is from Sylhet, was dropped off near his home and the fellowship of the rocks was broken. We settled in for another long drive. We made an impromptu stop at one of the numerous brick factories scattered across Bangladesh. Here, the workers immediately started snapping pictures of us with their phones.

Field School: Sylhet Tectonics

Most field trips have a “death march” hiking a long way through forest, swamps, hills or deserts to get to a remote outcrop. We have a “death bus ride” instead.

Field School: The Brahmaputra River

The first day was very light for the jet-lagged students, just a short introduction to the field school and some background, and then introductions all around as we started to get to know each other. The final group of nine students finally arrived around 9 p.m. They were the most worn-out, bedraggled bunch of travelers I have ever seen.

Tangail and the Start of the Field School

The Shahid Minar in Dhaka, the monument to language day on the site of the killings.  There are many smaller copies around Bangladesh.  On Language Day, they are covered by wreaths of flowers placed by everyone from politicians to school children.

Feb. 21 is Language Day in Bangladesh. It is a holiday, now adopted by the UN as International Mother Language Day. It commemorates a day in 1952 when a crowd of Bengali students protesting Pakistan’s adoption of “Urdu and only Urdu as the official language of Pakistan” were fired upon by the police. It marks the beginning of the move towards the independence of East Pakistan.
