This was the magnitude scale used historically by early seismologists.The Richter and MMS scales measure the energy released by an earthquake; another scale, the Mercalli intensity scale, classifies earthquakes by their effects, from detectable by instruments but not noticeable, to catastrophic. The energy and effects are not necessarily strongly correlated; a shallow earthquake in a populated area with soil of ... A Richter scale is normally numbered 1-10, though there is no upper limit. It is logarithmic which means, for example, that an earthquake measuring magnitude 5 is ten times more powerful than an ... Monitoring Earthquakes. 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. Measuring these waves help us determine the type of earthquake, its origin, and its strength/intensity. Many faults do not break the surface in an earthquake, so ...Earthquake Loma Prieta California 1989 The Loma Prieta earthquake was a major earthquake that struck the San Francisco Bay Area of California on October 17, 1989, at 5:04 p.m. local time.
