The actual model is a little more complex, but it roughly simplifies to the equation shown. R is the magnitude on the Richter scale of the earthquake. I is the intensity of the earthquake. The smallest seismic activity that can be measured has I = 1.The "size" of earthquakes is commonly expressed in two ways- magnitude and intensity. Magnitude is a measure of the total energy released during an earthquake. It is determined from a seismogram, which plots the ground motion produced by seismic waves. As devised by C.F. Richter in 1935, the magnitude scale allows us to compare earthquakes in relative terms.Mercalli intensity scale, a measure of earthquake impact; Japan Meteorological Agency seismic intensity scale, a measure of earthquake impact; Peak ground acceleration, a measure of earthquake acceleration (g or m/s 2) Acoustics.

Oct 11, 2023 · The intensity of earthquakes is measured on the Richter scale. It is a device which compares earthquakes. Whenever an earthquake comes, we can measure the intensity of it by using the Richter scale. An intensity of earthquake is measured or guessed by two things: first is amplitude and the other one is energy. Then what is amplitude? Intensity is a crude measure of earthquake size based on indirect, subjective descriptions, such as how strongly people reacted and the type and extent of building damage.
