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.
