Charles Richter suggested that the magnitude of an eadhquake can be expressed by... 

The magnitude is given on the Richter scale, which was developed in 1935 by Charles F. Richter of the California Institute of Technology as a mathematical device to compare the size of earthquakes. The magnitude of an earthquake is measured by the logarithm of the amplitude of waves recorded by seismographs. Adjustments are included for the variation in the distance between the various seismographs and the epicenter of the earthquake. On...

The first paper on earthquake magnitude was published by Charles F. Richter (1935). Therefore, often the term Richter scale is used as a synonym. Yet, this may be incorrect, especially for very large earthquakes and magnitudes measured at so-called teleseismic distances of more than 1,000-2,000 km away from the source for which the original Richter scale is not applicable. Richter s aim was (quote) ...
