What is a earthquake? Earthquakes happen when giant pieces of Earth's crust, called tectonic plates, suddenly slip past each other. These plates are always moving slowly, but they can get stuck. When the pressure builds up and finally releases, it sends energy through the ground, causing the shaking we feel on the surface.
If you feel the ground shake, Drop, Cover, and Hold On under a piece of heavy furniture until the vibration stops.
