Rich·ter scale

 (rĭk′tər)
n.
A logarithmic scale used to express the amount of energy released by an earthquake. Its values typically fall between 0 and 9, with each increase of 1 representing a 10-fold increase in energy.

[After Charles Francis Richter (1900-1985), American seismologist.]

Rich·ter scale

(rĭk′tər)
A scale used to rate the strength or total energy of earthquakes. The scale has no upper limit but usually ranges from 1 to 9. Each increase in whole number represents a tenfold increase in magnitude, so that an earthquake rated as 5 is ten times as powerful as one rated as 4. An earthquake with a magnitude of 1 is detectable only by instruments (seismographs); one with a magnitude of 7 is a major earthquake. See Note at earthquake.
