This study presents the analysis of the ambient seismic noise recorded on the Ca Lita landslide. In this perspective, we coupled the cross-correlation and polarization techniques with the objective of investigating the variations of the unstable slope's characteristics at two different époques. The results of this study revealed that both methods provide useful information to characterize the dynamic conditions of the active landslide. In particular, the combination of the cross-correlation and polarization techniques allow studying the wavefield evolution over time which seems to be a reliable precursor of the landslide's occurrence. Therefore, the obtained results confirm the potential of ambient seismic noise analysis as a reliable tool to improve our capabilities of slopes failure forecasting.

Abstract
This study presents the analysis of the ambient seismic noise recorded on the Ca Lita landslide. In this perspective, we coupled the cross-correlation and polarization techniques with the objective of investigating the variations of the unstable slope's characteristics at two different époques. The results of this study revealed that both methods provide useful information to characterize the dynamic conditions of the active landslide. In particular, the combination of the cross-correlation and polarization techniques allow studying the wavefield evolution over time which seems to be a reliable precursor of the landslide's occurrence. Therefore, the obtained results confirm the potential of ambient seismic noise analysis as a reliable tool to improve our capabilities of slopes failure forecasting.
