| Zusammenfassung |
Many destructive shallow landslides hit villages in the Peloritani Mountains
area (Sicily, Italy) on 1 October 2009 after heavy rainfall. The
collection of several types of spatial data, together with a landslide
inventory, allows the assessment of the landslide susceptibility by applying
a statistical technique. The susceptibility model was validated by
performing an analysis in a test area using independent landslide
information, the results being able to correctly predict more than 70% of
the landslides.
Furthermore, the susceptibility analysis allowed the identification of which
combinations of classes, within the different factors, have greater
relevance in slope instability, and afterwards associating the most
unstable combinations (with a short–medium term incidence) with the
endogenic processes acting in the area (huge regional uplift, fault
activity). Geological and tectonic history are believed to be key to
interpreting morphological processes and landscape evolution. Recent
tectonic activity was found to be a very important controlling factor in
landscape evolution. A geomorphological model of cyclical relief evolution
is proposed in which endogenic processes are directly linked to superficial
processes.
The results are relevant both to risk reduction and the understanding of
active geological dynamics. |
