In the last decade, there have been growing applications of long-term continuous ambient seismic noise systems to monitor landslides and potentially unstable rock sites. Two mains monitoring parameters can be alternatively or concurrently extracted from noise recording at potentially unstable sites: the fundamental resonance frequency of the unstable compartments can be derived from noise spectral analysis. The detection of irreversible drops in resonance frequency values and/or of negative velocity changes uncorrelated with external meteorological factors is of primary interest. In this work, there are two seismic stations were installed on either side of the Bossea cave. From the use of these stations, the goal is to understand and study the climate changes along the slides of the Bossea, analyzing the data from a geophysical and geomatic point of view.
