Toppled buildings and fissured roads merely scratch the surface of what happens when tectonic plates slip. Deep underground in Earth's mantle, an earthquake sends out spherical shear waves that break up into many phases after bouncing off the surface, Earth's core, and other interfaces. To help explain this intriguing process to students and the public, seismologists Michael Wysession and Saadia Baqer of Washington University in St. Louis have created a series of animations showing simulated earthquakes moving through a cross section of mantle. The flicks are also available with narration as a VHS video.∼saadia/page2.html
