The natural disaster that involves the shaking of the ground is an earthquake. Earthquakes occur when there is a sudden release of energy in the Earth's lithosphere, causing seismic waves. This release can be triggered by the movement of tectonic plates along faults and can vary in magnitude from minor tremors to devastating shocks. The intensity of an earthquake can cause severe destruction to buildings, infrastructure, and the environment, leading to potential loss of life. Earthquakes are often measured using the Richter scale or the moment magnitude scale, which quantify their strength and impacts.
