WebJul 30, 2024 · An earthquake can push and pull the ground, tearing the surface and pushing the ground apart and upward. These are known as “surface ruptures.” A surface rupture may occur suddenly during an … WebEarthquakes occur when a critical amount of stress is applied to the Earth’s crust and the crust responds by moving. According to the elastic rebound theory, rocks can bend elastically up to a point, until they finally break. The rocks then snap apart, releasing energy in the form of seismic waves ( Figure 10.1 ).
