Applying Nanoseimic Monitoring by seismic small-arrays at the soft rock Super-Sauze mudslide in the French Alps, we observed fracture processes of slope material, also called slidequakes. The time-frequency signature of these events resembles the impulsive signals from local earthquakes by brittle fracture of Earth crust. We could locate the slidequakes up to some hundred m off the arrays, and determine ML between –3 and –1. However, due to the very poor SNR neither precise depths nor moment… CONTINUE READING
