This work aims the analysis of the statistical data for a disaster situation. The statistical research of this paper is based on the devastating incident in Rieti for which we used the statistical observation, the primary data processing and we obtained the statistical indicators, and we analysed and interpreted the results of the collected data processing. The used statistical indicators have the role to allow the quantification of certain mass phenomena. In the present times, the numerical modeling represents the only tool to perceive the evolution of the seismic activity in time and space. Even if the process of generating earthquakes is influenced by a complex of certain physical and chemical processes, there is no system to simulate and analyse the seismic process in its complex form, anywhere in the world.
