WebMeasurement of the severity of an earthquake can be expressed in several ways, but the two most common scales used by seismologists are intensity and magnitude. Earthquake intensity. Intensity is a qualitative measure of the strength of shaking caused by an earthquake determined from the observed effects on people, objects and buildings.

How Are Earthquakes Measured? Caltech Science Exchange
The Richter scale was defined in 1935 for particular circumstances and instruments; the particular circumstances refer to it being defined for Southern California and "implicitly incorporates the attenuative properties of Southern California crust and mantle." The particular instrument used would become saturated by strong earthquakes and unable to record high values. The scale was replaced in the 1970s by the moment magnitude scale (MMS, symbol Mw ); for earthquakes adeq… Web7 rows · Mar 31, 2024 · Richter scale (ML), quantitative measure of an earthquake ’s magnitude (size), devised in 1935 ... WebOct 2, 2024 · This moment magnitude, Mw, is not based on seismometer readings at all but on the total energy released in a quake, the seismic moment Mo (in dyne-centimeters): Mw = 2/3 log ( Mo) - 10.7 This scale therefore does not saturate. Moment magnitude can match anything the Earth can throw at us. semi boneless smoked ham recipe
