Oct 4, 2023 · The Richter magnitude scale is used to measure the strength or magnitude of an earthquake. It is the most commonly used scale and assigns a number between 1 and 10 based on the amount of energy released by the earthquake. The larger the magnitude, the greater the intensity of the earthquake. About. 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. Remember that for each unit increase in magnitude:30 de mai. de 2011 ... A few different scales measure how strong an earthquake is.
