For all other earthquakes, the moment magnitude (Mw) scale is a more accurate measure of the earthquake size. Although similar seismographs had existed since the 1890's, it was only in 1935 that Charles F. Richter, a seismologist at the California Institute of Technology, introduced the concept of earthquake magnitude.

The moment magnitude scale (Mw) is a logarithmic scale used to measure the size of earthquakes. It is based on the seismic moment, which is a measure of the energy released by an earthquake. The seismic moment is calculated by multiplying the area of the fault that ruptured by the average amount of slip and the rigidity of the rock.

Magnitude scales, like the moment magnitude, measure the size of the earthquake at its source. An earthquake has one magnitude. The magnitude does not depend on where the measurement is made. Often, several slightly different magnitudes are reported for an earthquake. This happens because the relation between the seismic measurements and the magnitude is complex and different procedures will ...23 hours ago · By The Associated Press. October 22, 2023, 8:12 AM.
