This animation shows both the movement of the three basic waves (P, S, and surface) and the effect of the waves on a building. The three seismograms produced by a modern seismograph station show that the P wave is more visible on the vertical component and the S wave amplitude is larger on the horizontal components.
Animations and videos are made in partnership with Earthscope, USGS, and Volcano Video & Graphics.
