Subscribe to our channels on YouTube & Telegram.Not long after devising his scale, in 1936, Charles Francis Richter, in collaboration with Gutenberg, proposed a new magnitude that was based on the amplitude of surface waves (this time thinking of longer distances, and greater than 20 seconds long. This magnitude is still used today to generate the first estimates of the power of an …

The handy thing about the Richter scale is that for most earthquakes of interest, the magnitudes end up being numbers that range from about 3 - 9 and these are numbers easily understood by people. (In fact the scale itself does not set an upper or lower limit; limits of earthquake size are set by the Earth). Moment MagnitudeThe Richter scale is a base-10 logarithmic scale, meaning that each order of magnitude is 10 times more intensive than the last one. In other words, a two is 10 times more intense than a one and a three is 100 times greater. In the case of the Richter scale, the increase is in wave amplitude. That is, the wave amplitude in a level 6 earthquake ... OTOH, Richter is a magnitude scale, i.e. energy released at the hypocenter/focus. $\endgroup$ – Florian Jenn. Apr 22, 2015 at 15:54 ...
