Passive Seismic Monitoring Using a Migration Technique

C023 Z-99 Summary PASSIVE SEISMIC MONITORING USING A MIGRATION TECHNIQUE SUSANNE RENTSCH STEFAN BUSKE STEFAN LÜTH and SERGE A. SHAPIRO Institut für Geologische Wissenschaften Fachbereich Geophysik Freie Universität Berlin Malteser Strasse 74-100 12249 Berlin Germany In this paper we present a new approach for location of seismic sources which is based on principles of wave field back-propagation using multicomponent data. The use of migration techniques for imaging of seismic sources has the advantage that precise picking of arrival times is not required. Our approach requires only a preliminary selection of event time intervals and is much less sensitive to this
