Abstract
The choice of the regions is essential in the application of the algorithm CN, therefore a seismotectonic criterion for their definition is tested. In order to take into account the geodynamic complexity characterising the Italian peninsula, we established to strictly follow the seismotectonic zones, including in each region only zones with similar seismogenic behaviour and the transitional zones connected to them. Three regions have been successfully defined in this way, corresponding approxi- mately to the North, Centre and South of Italy. The reduction of the space-time uncertainty and the increase of the stability of prediction results obtained with this regionalisation, with respect to the previousapplicationsofCNinItaly(KEILIS-BOROKetal.,1990;COSTAetal.,1995,1996),canbe interpreted as a validation of the seismotectonic model.Pubblicazioni consigliate
