Many Bayesian statistical procedures are used to observe the probability distributions that an event will have. In this paper, we use Bayesian method to obtain important information about the magnitude and time in which earthquakes occur in areas where seismic events occur frequently.

We analyze the region of Italy bounded by the longitudes 12.3-13.6 and the latitudes 41.6-44. We consider the events with magnitude greater than 4. The results show that the Bayesian based methods are much better than the classical statistical method.
