Abstrakt

In the framework of a multidisciplinary project, 3D refraction tomography and passive microseismic data were acquired on an unstable rock slope in the western Swiss Alps. The final refraction tomogram revealed a conspicuous zone of extremely low velocities indicative of a highly fractured and thus unstable rock mass. Analyses of about 250 microseismic events located within the study area offered further information on the kinematic and dynamic behavior of the rock slope. The highest activity was located near the scarp of a recent rock slide. Both the tomographic image and the seismicity pattern provided critical information for future hazard analyses and the implementation of appropriate countermeasures.
