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.

New pictures in the journal Nature Geoscience may help resolve a debate about how new crust forms at mid-ocean ridges where earth’s tectonic plates are slowly pulling apart.

The 2,000-meter tall Bárðarbunga volcano in Iceland is at risk of eruption, an event that could send a cloud of ash and steam high into the atmosphere and cause extensive disruptions in air travel, among other effects, according to media reports. Earth Institute scientist Ben Orlove looks into it on the Glacier Hub blog.

Lamont-Doherty Earth Observatory graduate student Natalie Accardo recently returned from Tanzania and Malawi, where she installed seismic instruments in both countries alongside Lamont seismologists Donna Shillington and Jim Gaherty. Natalie produced this video, which shows the scientists and their Tanzanian colleagues conducting a “stomp test” at one of their sites in the Tanzanian village of Manda.

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

Sunset over the  Brahmaputra River as we prepare to depart the region for NE Bangladesh.

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.
