Abstract

Geological and geophysical data of an area of central Italy have been used for statistically comparing with the distribution of the mean seismic deformation. This parameter has been calculated by adding the square root of the energy released by earthquakes inside a cell, the dimensions of which have been fixed after performing an analysis of spatial autocorrelation. Underground temperatures, fault length, and topographic altitude showed a good single linear correlation with seismicity. Factor analysis has been employed to reduce the number of original variables, taking into account their mutual correlation; then, with the new uncorrelated variables, a good multiple linear correlation has been found, considering seismic deformation as a dependent variable. The analysis of residuals for the multiple regression shows the existence of areas with different seismic activity than predicted by the model: a discussion of the residuals pattern follows, considering the geological setting of the area.
