Investigations on Local Seismic Phases and Evaluation of Body Waves Magnitude

Abstract

For near events, synthetics seismograms are computed using BOUCHON' s method, for various heterogeneous structures. A special emphasis is put on topographic irregularities. This work was presented in the poster session at the 10th annual DARPA/AFGL SEISMIC RESEARCH SYMPOSIUM (2-5 May 1988). The programs used for this work are now implemented on our new SUN 3/280 system. For teleseisms, the main effort was first to obtain attenuation models between Eastern Kazakh and several regions in France. The application of those results to source functions for a series of events recorded in France. The application of those results to source functions for a series of events recorded in France is currently being done. A first by-product from this study was a re-evaluation of the magnitude of all events and a determination of stations corrections. Keywords: Source function; Synthetics seismogram; Attenuation topographic effect; Magnitude.
