seismic wave wave generated by an earthquake
surface wave seismic wave that moves rock particles in a backward, rolling motion and also in a side-to-side, swaying motion
mohorovicic discontinuity separates the crust and the upper mantle
earthquake vibrations, or shaking, produced when rocks break along a fault
crust rigid, rocky outer surface of the Earth
focus point below Earth’s surface where energy is first released in the form of seismic waves
epicenter point on Earth’s surface directly above the earthquake focus
Mercalli scale used to measure the strength of an earthquake based upon damage.
Richter Scale scale that compares the magnitude of an earthquake recorded by seismographs.
secondary wave seismic wave that moves rock particles at right angles to the direction of the wave
