Web2 days ago · For instance, if a deflection of one-thousandth of a millimeter at a distance of 100 kilometers indicates a magnitude 0 earthquake, then motion of 1 millimeter (three orders of magnitude or 1000 times the motion of the magnitude 0 earthquake) at the same distance would represent a magnitude 3 earthquake.

WebMar 31, 2024 · The moment magnitude ( MW or M) scale, developed in the late 1970s by Japanese seismologist Hiroo Kanamori and American seismologist Thomas C. Hanks, … WebThe moment-magnitude scale is logarithmic, so an increase of one unit means an earthquake is 10 times bigger, with about 30 times the energy produced. Small earthquakes have about the same value on the Richter scale and the moment magnitude scale, so Richter is fine for those. But, larger earthquakes are better measured as moment magnitude ...
