Earthquake

An earthquake is a sudden and intense shaking of the ground, resulting from the movement of tectonic plates beneath the Earth’s surface. This seismic activity occurs when accumulated stress along geological faults is released, producing seismic waves that propagate through the Earth, causing vibrations. Earthquakes can vary in magnitude, intensity, and duration, and they can lead to significant destruction, particularly in populated areas. They are often measured using seismographs, which provide data on the earthquake’s location, depth, and strength, typically expressed on the Richter or moment magnitude scale. Earthquakes can also trigger secondary phenomena such as tsunamis, landslides, and aftershocks.
