If a serious cyclone were to strike Mumbai, the results could be catastrophic, says a study underway at Columbia.

It is the black before dawn at the gate to the Kanha Tiger Reserve, in the highlands of central India. The still air carries a dank, penetrating chill. But it is hardly quiet. A buzzing line of tourists is forming at the ticket booth, peddlers are pouring steaming cups of tea. Groups of green-uniformed rangers chat… read more
The forested Kanha Tiger Reserve, in the highlands of central India, is home to an abundance of rare wildlife. It also used to be home to thousands of people—that is, until they were moved out by the government to make way for endangered creatures.
The Indian state of Jharkhand has plentiful rainfall, but most of that water runs off before it can be put to use by farmers, who struggle to make a living. To help improve irrigation and crop productivity, the Centers for International Projects Trust and Ranchi’s Birsa Agricultural University turned to a simple traditional technology, “dobhas,” small ponds that can store rainwater for months at a time.
When Sunita, a student in rural South India, got her period for the first time she was sure she was on the brink of death.
A new film takes viewers from the eastern highlands of India to the booming lowland metropolis of Dhaka, the capital of Bangladesh–and explores an ever-more detailed picture of catastrophic earthquake threat that scientists are discovering under the region.
This summer, the Earth Institute is offering Columbia students opportunities to intern within various departments and research centers at the institute. All full-time Columbia and Barnard students are eligible to apply.
We finished our work at the river transect. Now we had one more sample to collect. Alamgir had arranged for drillers at this new site, but they were delayed because of a knife fight between two villages over some property.
The success of the tube wells for drilling and obtaining samples was a great boon to our field program. We drilled three additional tube wells to complete a five-well transect across the abandoned river valley. When we date the samples, we will find out if the river switched position suddenly, possibly from an earthquake.
The resistivity testing was hampered by bad roads and flooded fields. The augering was proving similarly difficult in the thick muds of the abandoned channel. It was time to change to our alternative plan: drilling with tube wells. That worked better and we had turned a corner.
