Creating Earthquake Heat Maps: Temperature Spikes Leave Clues in the Rock
When a fault slips, the temperature can spike by hundreds of degrees, high enough to alter organic compounds in the rocks and leave a signature. Lamont scientists have developed methods to use those organic signatures to reconstruct past earthquakes and better understand what controls them.

Learning from Slow-Slip Earthquakes
Off the coast of New Zealand, there is an area where earthquakes can happen in slow-motion as two tectonic plates grind past one another. These slow-slip events create an ideal lab for studying fault behavior along the shallow portion of subduction zones.

Spy Satellites Reveal the Himalayas’ Changing Glaciers – in 3D
Declassified spy satellite images are beginning to provide the first consistent look at how glaciers across the Himalayas are changing and what future water supplies might look like for millions of people.

By studying thousands of buildings and analyzing their electricity use, Columbia Climate School Dean Alexis Abramson has been able to uncover ways to significantly cut energy consumption and emissions. Watch the Video: “Engineering a Cooler Future Through Smarter Buildings“
