The quake that shook central Mexico this week was a 7.1. Sep 29, 2023 · 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: The Richter Scale is based on a reading from a seismograph — a device that detects the waves sent out by an earthquake. Each number on the Richter scale indicates an increase of ten times the force of the previous number. For example, the Richter scale rating of 2 is ten times the force of a level 1.The moment-magnitude scale is logarithmic, so an increase of one unit means an earthquake is 10 times bigger, with about 30 times the energy produced. Small earthquakes have about the same value on the Richter scale and the moment magnitude scale, so Richter is fine for those. 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:See below Earthquake magnitude. A number of different intensity scales have been set up during the past century and applied to both current and ancient destructive earthquakes. For many years the most widely used was a 10-point scale devised in 1878 by Michele Stefano de Rossi and Franƈois-Alphonse Forel. Plug magnitude values of 5.0, 6.0, and 7.0 into the equation above. The energy released by an M5 earthquake is about 2.8 x 10 12 joules. An M6 earthquake releases 7.8 x 10 13 joules, and an M7 radiates 2.1 x 10 15 joules. If you don't have a sense for what these numbers mean, the bomb dropped on Hiroshima released about 7.4 x 10 12 joules.
