It is logarithmic which means, for example, that an earthquake measuring magnitude 5 ...Jul 1, 2021 · Detailed Description. Earthquake Intensity - Modified Mercalli Intensity (MMI) Scale. The Modified Mercalli Intensity value assigned to a specific site after an earthquake has a more meaningful measure of severity to the nonscientist than the magnitude because intensity refers to the effects actually experienced at that place. The lower numbers ... These two ratings describe the power of the earthquake from two different perspectives. The most common standard of measurement for an earthquake is the Richter scale, developed in 1935 by Charles F. Richter of the California Institute of Technology. The Richter scale is used to rate the magnitude of an earthquake -- the amount of energy it ... 6152 Injured. On Friday 11 March 2011, an earthquake measuring 9 on the Richter Scale occurred off the north-east coast of Japan, triggering a ten-metre tsunami. A nuclear emergency was declared following explosions at various nuclear plants in the Fukushima area. Abnormally high levels of radioactive substances were later detected in seawater ...For all other earthquakes, the moment magnitude (Mw) scale is a more accurate measure of the earthquake size. Although similar seismographs had existed since the 1890's, it was only in 1935 that Charles F. Richter, a seismologist at the California Institute of Technology, introduced the concept of earthquake magnitude.Earthquake size, as measured by the Richter Scale is a well known, but not well understood, concept. The idea of a logarithmic earthquake magnitude scale was first developed by Charles Richter in the 1930's for measuring the size of earthquakes occurring in southern California using relatively high-frequency data from nearby …The Richter scale is an outdated method for measuring magnitude that is no longer used by the USGS for large, teleseismic earthquakes. The Richter scale measures the largest wiggle (amplitude) on the recording, but other magnitude scales measure different parts of the earthquake.
