Quantification of Earthquakes


Because earthquakes are the result of complex geophysical processes, it is not a simple matter to find a single measure of the size of an earthquake. Further, extremely large earthquakes saturate the conventional magnitude scale. Recent estimates of energy released by such earthquakes suggest values high enough to have possible implications for plate motion, the Chandler wobble and rotation of the Earth.
