What is a erathqake?

Answer 1

An earthquake is the shaking of the Earth's surface caused by the sudden release of energy in the Earth's lithosphere, usually due to tectonic plate movements. This release generates seismic waves that can vary in intensity and duration. Earthquakes can lead to significant damage, particularly in populated areas, and are measured using seismographs. They can also trigger secondary hazards, such as tsunamis and landslides.
