Ripples on a pond

http://www.iris.edu/hq/waves A stone causes ripples to radiate out across the surface of a pond in all directions. Such imagery is the analog or familiar situation for a classic seismology instructional analogy "Seismic waves radiate outward from an earthquake's epicenter like ripples on water."
