Severity of Earthquakes - Scales (InfoPlease.com) "The severity of an earthquake can be expressed in terms of both intensity and magnitude. The two terms are quite different, however, and they are often confused. Intensity is based on the observed effects of ground shaking on people, buildings, and natural features. It varies from place to place within the disturbed region depending on the location of the observer with respect to the earthquake epicenter. Magnitude is related to the amount of seismic energy released at the hypocenter of the earthquake. It is based on the amplitude of the earthquake waves recorded on instruments, which have a common calibration. Magnitude is thus represented by a single, instrumentally determined value." "The Richter magnitude scale was developed in 1935 by Charles F. Richter of the California Institute of Technology as a mathematical device to compare the size of earthquakes." Ten Deadliest Quakes Since 1900 (Bloomberg.com) "Today's earthquake in southern Iran that killed as many as 20,000 people is the deadliest since 2001, when more than 20,000 were killed in India." Lists "the most-deadly earthquakes worldwide since 1900, according to the U.S. Geological Survey." 12-03 The Ten Deadliest Earthquakes (Time.com) "The deadliest quake of all time might be one of the least talked about, considering it occurred nearly 450 years ago.
