Analyse des données accélérométriques pour la caractérisation de l'aléa sismique en France métropolitaine

Abstract : This work is devoted to the analysis of the accelerometric data from French metropolitan territory, recorded by the National Accelerometric Network (Réseau Accélérométrique Permanent, RAP), the deployment of which is under way since 1996, in order to provide elements for seismic hazard studies. A number of empirical strong ground motion models exists based on data from seismically active regions (USA, Japan...), but reevaluation of key parameters such as magnitudes or site effects is required in order to use these models in the French context.

First, the study of the moderate events data allows us to determine a homogeneous magnitude scale based on the seismic moment. Site responses for the RAP stations in the Pyrenees, the Alps and the Rhine Graben have also been computed. Attenuation models exhibit regional variations in France. Based on the previous results and on the data from the major events recorded by the RAP, empirical strong ground motion models suitable for France have been identified.
