Summary

This laboratory exercise reviews the basic concepts of how seismic body waves travel through the Earth and how seismologists use these waves to determine global Earth structure. Also, the students analyze waveforms recorded from an earthquake to determine the earthquake's location, magnitude, and focal mechanism.
