Past slope
instabilities at Quindici (one of the five towns of Campania that was hit
by catastrophic landslides on 5 May 1998) and in the Lauro Valley are
investigated to improve the understanding of the landslide history in the
area, as a mandatory step for the evaluation of the landslide hazard. The
research was performed by combining information on past slope
instabilities from both historical and geological data. From numerous
historical sources an archive consisting of 45 landsliding and flooding
events for the period 1632–1998 was compiled. Landslide activity was
also investigated by means of interpretation of multi-year sets of aerial
photos, production of Landslide Activity Maps, and excavation of trenches
on the alluvial fans at the mountain foothills. Detailed stratigraphic
analysis of the sections exposed in the trenches identified landslide
events as the main geomorphic process responsible for building up the fans
in the study area. Integration of historical and geological approaches
provides significant insight into past and recent instability at Quindici.
This is particularly valuable in view of the limitations of individual
sources of information. Application of such an approach offers potential
for improved hazard assessment and risk mitigation. |
