The Modified Mercalli intensity scale ( MM, MMI, or MCS) measures the effects of an earthquake at a given location. This is in contrast with the seismic magnitude usually reported for an earthquake. Magnitude scales measure the inherent force or strength of an earthquake – an event occurring at greater or lesser depth. From 1935 until 1970, the earthquake magnitude scale was the Richter scale, a mathematical formula invented by Caltech seismologist Charles Richter to compare quake sizes. The Richter Scale was replaced because it worked largely for earthquakes in Southern California, and only those occurring within about 370 miles of seismometers.While each earthquake releases a unique amount of energy, the magnitude values reported by different seismological observatories for an event may vary. Depending on the size, nature, and location of an earthquake, seismologists may use several different methods and even different magnitude scales to estimate magnitude. For historical reasons the most well-known measure of earthquake size is the earth- quake magnitude. There are now several different types of magnitude scales, ...Magnitude is a measure of the amplitude (height) of the seismic waves an earthquake’s source produces as recorded by seismographs.
