Probability distribution of earthquake magnitude?

06 December 2022 0 6K Report

As it is known that distribution of earthquake magnitude can be described by using Gutenberg-Richter recurrence law, which states that the number of earthquakes occurring annually from a given source is a log-linear function of the magnitude. My question is which probability distribution does the earthquake magnitudes follow. I mean, is it normal, log-normal, exponential probability distribution etc. ?
