Amer. 25 1 In the course of historical or statistical study of earthquakes in any given region it is frequently desirable to have a scale for rating these shocks in terms of their original energy, independently of the effects which may be produced at any particular point of observation. On the suggestion of Mr. H. O. Wood, it is here proposed to refer to such a scale as a ‘magnitude scale’. 1935 C. F. Richter in Bull. Seismol. Soc.

Astronomy. [After a Hellenistic use of ancient Greek μέγεθος (in Ptolemy, Almagest); compare post-classical Latin magnitudo (attested in this sense late 13th and late 17th centuries in British sources).] Each of the classes into which stars and other celestial objects have been placed according to their degree of brilliancy. Now regarded (according to a system introduced by the British astronomer N. R. Pogson in 1856) as a number on a continuous scale representing the negative logarithm of the brightness, such that a decrease of five magnitudes represents a hundred-fold increase in brightness and a decrease of one magnitude an increase of 2.512 times.Originally, stars ‘of the first magnitude’ were the most brilliant; later, when the size of this class was found to have become disproportionately large, negative magnitudes were introduced for the brightest objects. The ‘sixth magnitude’ includes objects that are barely visible to the naked eye; the seventh and lower magnitudes are telescopic only. The classification into ‘magnitudes’, originally a subjective one, is now a matter of photometric measurement. Formerly often denoted by the symbol m, as 2.m, 3.m.Before decimal or fractional numbers were used there was an intermediate stage illustrated by quots. 1796, 1826, and 1851.
