Investigations on Local Seismic Phases and Modeling of Seismic Signals

Abstract : During this three years period of activity we have worked on the basic topic of our grant that is to say 'Investigations on local seismic phases and modeling of seismic signals' but we have also enlarged this research in some cases to teleseismic distances. We also worked on data processing of seismic waves recorded at regional distances by a mini-array in order to improve the capability of automatic detection and localisation of events. Within the frame of the study of regional phases, we have used methods of numerical simulation to model data from the french and spanish seismic networks in order to study the influence of crustal heterogeneities on the attenuation of these phases.
