Abstract
A method based on waveform inversion has been developed in order to locate and provide the focal mechanisms of microseismic events from the continuous records of dense surface seismic arrays. A step of detection is used prior to waveform inversion to enable data processing in real-time. In this method, after preliminary analysis of a reference sh ot by an operator, detection, localization and source mechanism characterization are automatic. The expertise of the operator is needed a second time to validate or reject detected and located microseismic events.
