Earthquakes are sudden shaking of the Earth's crust. They usually happen when tectonic plates beneath the Earth's surface suddenly move and rub against each other. This movement releases a lot of energy, causing vibrations that travel through the ground. As a result, buildings can collapse, roads can crack, and sometimes even tsunamis can be triggered if the earthquake occurs under the ocean.
