All earthquakes start with P waves, which are fast moving and cause little damage. Because these corals bulk up in layers, like trees growing in concentric rings, scientists can use their skeletons to chart relative water level changes over time. Earthquakes are the result of plate tectonics, or shifting plates in the crust of Earth, and quakes occur when the frictional stress of gliding plate boundaries builds and causes failure at a fault line.
