Abstract
THIS communication outlines a probability model which seems to provide an adequate basis for making predictions concerning the occurrence of largest earthquake magnitudes over time: (a) The number of earthquakes in a year is a Poisson random variable with mean α; (b) X, the earthquake magnitude, is a random variable distributed with cumulative distribution function:
