To test the reliability of such a methodology, strong motion recordings of ground acceleration, obtained from a SMA-1 analog accelerograph, and the one obtained by a digital instrument installed in the same pillar, were analyzed in the time domain. Displacements were obtained by double integration of the acceleration and therefore analyzed. The second part of this paper underlines some possible improvements in collecting, selecting and analyzing statistical data based on strong motion recordings. As an application the original Sabetta and Pugliese database for the ground motion prediction of PGA is investigated. First a databank extension due to new digital measurement events, marked by a bigger accuracy, was implemented. Secondly a better statistical way of dealing such spatial data in ground prediction relations, making use of Geographically Weighted Regression (GWR), is illustrated. As a result a substantial reduction in epistemic uncertainty in relative hazard maps is evidenced.
