WebEarthquakes are the result of sudden movement along faults within the Earth. The movement releases stored-up ‘elastic strain’ energy in the form of seismic waves, which propagate through the Earth and cause the ground surface to shake. Such movement on the faults is generally a response to long-term deformation and the buildup of stress. WebMar 24, 2024 · An earthquake occurs when two blocks of the Earth suddenly slip past one another. The surface where they slip is called the fault or the fault plane. The location below the Earth’s surface where an earthquake begins is called the hypocentre, and the location directly above it on the surface of the Earth is called the epicentre.
