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. dylan bongiornoWebThis indicates that the amplitude of the ground motion detected by a seismograph increases by a factor of 10 for every whole number increase on the magnitude scale.
