Abstract
The magnitude of an earthquake was originally defined (Richter, 1935) as the common logarithm of the maximum displacement, expressed in microns, of the trace written by a standard torsion seismometer at an epicentral distance of 100 kilometers. When this trace amplitude is one micron the magnitude is accordingly zero.
