2. Definitions S-wave-is a seismic body wave that shakes the ground back and forth perpendicular to the direction the wave is moving. P-wave-is a seismic body wave that shakes the ground back and forth in the same and opposite direction the wave is moving. L-wave- seismic waves that travels along the surface or right below the surface.
3. Definitions cont. Epicenter-is the point in the crust where a seismic rupture begins. Focus-is the point in the earth where an earthquake begins.
4. Definitions cont. Mercalli Scale-is the scale to measure the intensity of an earthquake. Richter Scale-is the scale to measure an earthquakes magnitude.
