| Abstract: | The principle of maximum entropy is used to study the relationship of earthquake magnitude and frequency and obtain the probability distribution function for magnitude under the condition of discrete magnitude. The results show: (1) the number of events equal to or greater than M should be determined by discrete summation rather than integration method, (2) when unlimited upper bound to magnitude is given, the b value is equal for the Gutenberg relation and the Richter relation. When an upper bound Mk is assumed, the Richter relation may not be a linear relationship. |
