Abstract
In rock slope analysis, formation and growth of microcracks are usually coupled with the propagation of elastic waves that can be detected by a suitable microseismic monitoring system. The correct analysis and interpretation of the recorded activity can provide information on the size and the type of the rupture mechanisms. A combination of the coherency computation and the source location techniques, typically used in seismic signal processing, is here proposed to this aim. The application to a microseismic dataset recorded by the microseismic monitoring system installed on the Matterhorn Peak, has evidenced the effectiveness of this approach. In particular the coherency has allowed to identify a set of similar appearing events, while the location of the corresponding hypocenters has evidenced the alignment of the sources on a planar surface, whose orientation is closed to the orientation of a discontinuity system resulting from a morphostructural survey.
