  In a rebroadcast from Nov. 14, 2010, Keith talks with seismology professor Brian Stump, Albritton Professor of Earth Sciences, Dedman College of Humanities and Sciences, with SMU.  Stump explains why the earth's crust differs around the world, and why there is an increasing detection of smaller quakes worldwide.  An interesting question arises during the interview: Could nuclear weapons be used to relieve pressure along fault lines?  Plus, Stump explains how earthquakes cause low frequency acoustic waves in the atmosphere.
