The size of the earthquake on the Richter scale - the ...The Richter scale was found to not transfer very well from the San Andreas fault zone, a transform plate boundary, to the much more powerful earthquakes that occur at convergent plate boundaries, particularly subduction zone earthquakes. Therefore, the Richter scale has been replaced by the moment magnitude scale, symbolized as M w. ….

Richter scale (M L), quantitative measure of an earthquake’s magnitude (size), devised in 1935 by American seismologists Charles F. Richter and Beno Gutenberg. The earthquake’s magnitude is determined using the logarithm of the amplitude (height) of the largest seismic wave calibrated to a scale by a seismograph. Although modern scientific ...Mar 3, 2021 · The MMI scale estimates the intensity of shaking in the region around the earthquake epicenter with a range of values that varies across the landscape corresponding to felt reports of shaking and damage. An earthquake with a magnitude of 6.7 struck the southern California city of Northridge in 1994.

Earthquakes between magnitude 2.5 and 5 will be increasingly felt but generally do little damage. When earthquakes scale to over magnitude 5 their effects become highly significant. Earthquakes of magnitude 5 to 6 will almost always cause some damage, but most of it will be architectural rather than structural.Northridge Earthquake: January 17, 1994.
