Figure 8
State of activity of surveyed landslides for both preseismic years (a) and the postseismic year (b) (top) with respect to the preceding years. Histograms relating landslides in the groups with the involved lithologies (bottom) are shown. A clear increase in the number of landslides and number of reactivations in postseismic time is visible. (c) Differential values computed between the postseismic year and preseismic years for the days of activity and inactivity period; for several landslides, an increase in their mobility in the postseismic period is visible (negative differential for the inactivity period and positive differential for the days of activity).
