| Zusammenfassung |
The tectonic stresses that produced the uplift of Apennine chain ridge in
southern Italy generated advanced buried thrusts of allochthonous deposits
that induced deformations of foredeep deposits. This thrust may cause giant,
deep-seated landslides at the front of the chain. Starting from a specific
case history in low Biferno Valley, this work presents how giant, deep-seated
landslides along the front of the chain may be generated by the thrust of
allochthonous nappe of the chain. In addition, the influence that these huge
phenomena may have on landslide and flood susceptibility and on natural
hazards of the involved area is analysed.
The work presents an interpretation of local morphology and stream network
paths of low Biferno Valley as a consequence of a giant, deep-seated landslide
affecting the right side of the valley. The proposed interpretation is
supported by numerical geomorphological analyses of the area at stake. It is
shown how both the morphologies of the catchments of the river Biferno and its
tributary Cigno and stream paths are strongly conditioned by this large,
deep-seated landslide. This landslide deviates the stream paths affecting
both the flooding susceptibility of low Biferno Valley and landslide
susceptibility on the left side of Biferno Valley. |
