An earthquake is a naturally induced shaking of the ground, caused by the fracture of rock within the Earth and the resulting sliding of rocks past one another along a geological fault The sudden movement of rocks along a fault causes vibrations that transmit energy through the earth in the form of waves. Waves that travel in the rocks below the surface of the earth are called body waves, and there are two types …showed first 75 words of 399 total…
