All magnitude scales retain the logarithmic character of the original and are scaled to have roughly comparable numeric values typically in the middle. Richter scale ML quantitative measure of an earthquake s magnitude size devised in 1935 by American seismologists Charles F. Magnitude calculations are based on a logarithmic scale so a ten-fold drop in amplitude decreases the magnitude by 1If an amplitude of 20 millimetres as. Seismic magnitude scales are used to describe the overall strength or size of an earthquake These are distinguished from seismic intensity scales that. Magnitudes are based on a logarithmic scale base 10 What this means is that for each whole number you go up on the magnitude scale the amplitude of the..

The Richter scale ˈ r ɪ k t ər also called the Richter magnitude scale Richters magnitude scale and the GutenbergRichter scale is a measure. The Richter scale and how it measures earthquake magnitude The Richter scale calculates an earthquakes. Seismic magnitude scales are used to describe the overall strength or size of an earthquake These are distinguished from seismic intensity scales that. In particular for very large earthquakes moment magnitude gives the most reliable estimate of earthquake size. Magnitude scales can be used to describe earthquakes so small that they are expressed in negative numbers..
Although numerousintensity scales have been developed over the last several hundred years to evaluate the effects of earthquakes the one currently used in the United States is the Modified Mercalli. 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. Felt by a few people especially on upper floors Noticeable indoors especially on upper floors but may not be recognized as an earthquake Felt by many indoors few outdoors. The Mercalli Scale The Mercalli scale has 12 divisions using Roman numerals from I to XII Not felt except by a very few under especially favorable circumstances. Earthquake Intensity - Modified Mercalli Intensity MMI Scale The Modified Mercalli Intensity value assigned to a specific site after an earthquake has a..
