Charles Francis Richter in southern California. Since 1935, several other magnitude scales have been developed. Richter was an active and avowed naturist. He travelled to many nudist communities with his wife. At his retirement party, a group of colleagues at Caltech, called the "Quidnuncs," played and sang a ditty titled "Richter Scale," which gave examples of earthquakes in American history, told in ballad style. Richter was not amused, however; he was furious. The author of the song, Kent Clark, stated in a 1989 interview that Richter enjoyed the song. The song is played on the Dr. Demento show occasionally. Richter died of congestive
Richter magnitude scale isolated area. Several scales have historically been described as the "Richter scale", especially the "local magnitude" formula_2 and the surface wave formula_3 scale. In addition, the "body wave magnitude", formula_4, and the "moment magnitude", formula_5, abbreviated MMS, have been widely used for decades. A couple of new techniques to measure magnitude are in the development stage by seismologists. All magnitude scales have been designed to give numerically similar results. This goal has been achieved well for formula_2, formula_3, and formula_5. The formula_4 scale gives somewhat different values than the other scales. The reason for so many different ways to measure
