Richter scale
Richter scale , measure of the magnitude of seismic waves from an earthquake , devised in 1935 by the American seismologist Charles F. Richter (1900-1985). The scale is logarithmic; that is, the amplitude of the waves increases by powers of 10 in relation to the Richter magnitude numbers. The... Read more |

Mercalli scale
Mercalli scale An earthquake-intensity scale based on direct observation. Devised by G.Mercalli, it ranges from scales I (not felt) and II (felt by most people at rest) to VII (difficult for a person to remain standing), X (most structures destroyed), and XII (total devastation). It is not a... Read more |

Earthquakes in Southern California
earthquake trembling or shaking movement of the earth's surface. Most earthquakes are minor tremors. Larger earthquakes usually begin with slight tremors but rapidly take the form of one or more violent shocks, and end in vibrations of gradually diminishing force called aftershocks. The...
