However, since the Energy Magnitude and MomeSeveral scales have been defined, but the most commonly usEarthquake Magnitude. Earthquake magnitudes are determined by m Richter scale, widely used quantitative measure of an earthquake’s magnitude (size), devised in 1935 by American seismologists Charles F. Richter and Beno Gutenberg. Magnitude is determined using the logarithm of the amplitude (height) of the largest seismic wave calibrated to a scale by a seismograph.Therefore, the greater the magnitude, the more energy is released during the earthquake. Following this logic, this would be a logarithmic scale. Put another way, the increase in magnitude of 1 unit would correspond to the increase in energy release of 30 units. And it is based on this theory that the Richter Scale arises. Magnitude is the measure of the intensity of an earthqua Mercalli Intensity Scale. Earthquakes are described in terms of what nearby residents felt and the damage that was done to nearby structures. Richter magnitude scale.
