Horizontal Seismograph Slowed

Animation of the vertical seismograph above slowed down to show compressive behavior of the P wave in the direction the wave is traveling and the shearing behavior of the S wave perpendicular to the direction of wave travel. Although the arrow shows gross movement, remember that this happens on a microscopic scale in the Earth.
