Earthquakes are primarily caused by sudden movements of rocks within the Earth's crust. These movements release energy that generates seismic waves, which we feel as shaking. Earthquakes often occur along faults, which are fractures in the Earth's crust where tectonic plates meet. Understanding this helps in earthquake preparedness and risk mitigation in vulnerable areas.
