Earthquake magnitude scale
WebThe earthquake measured 6.8 on the surface-wave magnitude scale (M s ); [8] on the moment magnitude scale (M w ), it measured 6.7. [1] According to the United States Geological Survey, the earthquake was a result of shallow strike-slip faulting on the western margin of the Sichuan Basin.

For large earthquakes worldwide, the moment magnitude scale (MMS) is most common, although M s is also reported frequently. The seismic moment, M0 , is proportional to the area of the rupture times the average slip that took place in the earthquake, thus it measures the physical size of the event. See more The Richter scale , also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale, is a measure of the strength of earthquakes, developed by Charles Francis Richter and presented in his … See more Prior to the development of the magnitude scale, the only measure of an earthquake's strength or "size" was a subjective … See more These formulae for Richter magnitude ML are alternatives to using Richter correlation tables based on Richter standard seismic … See more 1. ^ Kanamori 1978, p. 411.

WebThe first earthquake magnitude scale was invented by Charles Richter for southern California in 1935. Unlike seismic intensity, which measures the strength of shaking and varies according to distance from the quake and other factors, the magnitude is intended to measure the intrinsic size of an earthquake.
