WebJan 5, 2024 · Enter the two magnitudes you want to compare – for our example, these are 5.8 and 7.1. We find out that a magnitude of 7.1 is 20 times bigger (on a seismogram, in terms of amplitudes) and ~89 times stronger (in terms of energy release) than a 5.8 magnitude. The amplitude of shaking is 10 times larger. WebThe U.S. Earthquake Intensity Database (1638-1985) is a collection of damage and felt reports for over 23,000 U.S. earthquakes.

The Richter magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs (adjustments are included to compensate for the variation in the distance between the various seismographs and the epicenter of the earthquake). The original formula is: M L = log 10 A − log 10 A 0 ( δ ) = log 10 [ A / A 0 ( δ ) ] , {\displaystyl… The Richter magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs (adjustments are included to compensate for the variation in the distance between the various seismographs and the epicenter of the earthquake).
