WebSep 12, 2024 · The Richter Scale is a base-ten logarithmic scale. In other words, an earthquake of magnitude 8 is not twice as great as an earthquake of magnitude 4. It is 108-4=104=10,000 times as great! In this section, we will investigate the nature of the Richter Scale and the base-ten function upon which it depends. WebMar 31, 2024 · Richter scale (ML), quantitative measure of an earthquake ’s magnitude (size), devised in 1935 by American seismologists Charles F. Richter and Beno Gutenberg.
