Seismology S-P Earthquake Location
http://www.txessrevolution.org/SeismologyS_PIntro


The activity adapts the approach that L.W. Braile and S.J. Braile have named the Walk – Run method, in which S wave propagation is simulated by walking, and P wave propagation is simulated by running. The purpose of this activity is to model (1) the different speeds of P and S waves as they travel from the epicenter of an earthquake; and (2) simulated travel times via a technique used by seismologists to locate earthquakes. This technique is called the S and P Wave Travel Time Simulation or "S minus P" Earthquake Location Method.
