WebJan 5, 2024 · To calculate the amount of released energy from an earthquake, we've implemented Gutenberg and Richter's equation in this earthquake calculator: E = 10^ {1.5 M + 4.8} E = 101.5M +4.8 which is sometimes expressed as: \log E = 4.8 + 1.5 M, logE = 4.8 + 1.5M, or: M = \frac {2} {3} \log E - 3.2. M = 32 log E − 3.2. Most powerful earthquakes WebQuestion: The magnitude R, measured on the Richter scale, of an earthquake of intensity I is defined as R = log where lo is a minimum intensity used for comparison.
