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. When a magnitude 8.5 mega-earthquake struck off the Indonesian island of Sumatra in February 1861, it caused the land to convulse, stirring up a wall of water that crashed on nearby shores and killed thousands of people. When an earthquake begins, fast-moving P waves are detected, and emergency information can be disseminated before the arrival of slower-moving surface waves. The result is an accumulation of energy that bursts through rock in the way that sound waves piling up against a speeding fighter jet erupt in a sonic boom.
