In the Probabilistic Seismic Hazard approaches, often the refining of the results (hazard maps) is limited by difficulty in defining detailed seismogenetic zonation, due mainly to the limitation of the earthquake catalogues. However, the refining of the seismic hazard maps can be realized using a deterministic approach. Indeed, it is possible to introduce a priori information about source aspects inside each seismogenetic zone. This information can be viewed as an independent correction formula, theoretical and/or empirical, applied to the attenuation law. In this presentation, we illustrate how to introduce a priori source parameters such as fault mechanisms, directivity and fault geometry, inside the probabilistic approach. This modification will be applied to the seismic hazard map of the Central and Southern Apennines, Italy.
