What is the difference between an earthquakes “magnitude” and “intensity”?
Magnitude is a terminology used as measuring the energy released at the source of an earthquake, represented by a real number. Intensity is the one that describes the strength of ground shaking or effects on human bodies at a certain location produced by an earthquake. It is related to the acceleration of ground motion. For now, a seismograph can record ground acceleration well so that intensity is determined by the range of maximum ground acceleration and ranked by an integer. The definition of the ranks varies from country to country.
