_{How is the earthquake measured. We monitor earthquakes by measuring the seismic waves they generate. Seismic waves are generated when the two sides of a fault rapidly slip past each other. }

_{Moment magnitude, a quantitative measure of an earthquake's magnitude (or relative size), developed in the 1970s by Hiroo Kanamori and Thomas C. Hanks. Size calculations are tied to an earthquake's seismic moment rather than to the amplitudes of waves recorded by seismographs.The magnitude of an earthquake on the Richter scale can be defined by M=2/3log(E)-3.2, where E is the energy of the quake in joules. The 2011 Tohoku earthquake in Japan measured 9.1 on the Richter scale. The 1999 Hector Mine earthquake in eastern California had a magnitude of 7.1. Calculate the energy released by each earthquake.Can scientists predict earthquakes? Unfortunately scientists cannot predict earthquakes. The best they can do today is point out where fault lines are so we know where earthquakes are likely to occur. Fun Facts about Earthquakes.
