WebAn earthquake is a sudden, violent shaking of the ground caused by the sudden release of energy in the Earth’s lithosphere that creates seismic waves. Earthquakes range in size from those so weak people cannot … WebIntensity scales date from the late 19th and early 20th centuries, before seismographs capable of accurate measurement of ground motion were developed. Since that time, the divisions in these scales have been associated with measurable accelerations of the local ground shaking.
