Evaluation of the hazard density function for a site

In the paper an experimental statistical method is developed to follow the propagation of the seismic signal on the territory. The seismic intensity at the site is represented by a probability density function whose solution is given by the statistical elaboration of some recorded data, such as the epicentre intensity and location, the site intensity, the magnitude value, the time duration, the occurrence period, the peak acceleration, etc., of a series of historical earthquakes occurred in a reference Italian area.
