An Inter-Comparison of Coastal Vulnerability Assessment Methods

In this paper a Coastal Vulnerability Assessment method (CVA) was compared with the well-established CVI method in order to obtain validation data and discuss the different results. The structure of the proposed method relies upon a key parameter, known as impact index Ii, which accounts for wave climate, bathymetry and sediment data and depends on the wave run-up height, the seasonal and long-term erosion, and the efficiency of coastal protection structures. The comparison between this CVA and the existing CVI method was done on a test site already examined. The calculation of the different contributions of each method was transformed in appropriate vulnerability scores in order to examine and discuss the different results.

Geomorphic response to late Quaternary tectonics in the axial portion of the Southern Apennines (Italy): A case study from the Calore River valley: Geomorphic response to the Quaternary tectonics in the Calore R valley

The present study focuses on themorphotectonic evolution of the axial portion of the SouthernApennine chain between the lower Calore River valley and the northern Camposauro mountain front (Campania Region). A multidisciplinary approach was used, including geomorphological, field-geology, stratigraphical, morphotectonic, structural, Ar/Ar and tephrostratigraphical data. Results indicate that, from the Lower Pleistocene onwards, this sector of the chain was affected by extensional tectonics responsible for the onset of the sedimentation of Quaternary fluvial, alluvial fan and slope deposits. Fault systems are mainly composed of NW-SE, NE– SWandW-E trending strike-slip and normal faults, associated toNW-SE andNE–SWoriented extensions. Fault scarps, stratigraphical and structural data and morphotectonic indicators suggest that these faults affected the wide piedmont area of the northern Camposauro mountain front in the Lower Pleistocene–Upper Pleistocene time span. Faults affected both the oldest Quaternary slope deposits (Laiano Synthem, Lower Pleistocene) and the overlying alluvial fan system deposits constrained between the lateMiddle Pleistocene and the Holocene. The latter are geomorphologically and chrono-stratigraphically grouped into four generations, I generation: late Middle Pleistocene–early Upper Pleistocene, with tephra layers Ar/Ar dated to 158±6 and 113±7 ka; II generation: Upper Pleistocene, with tephra layers correlated with the Campanian Ignimbrite (39 ka) and with the slightly older Campi Flegrei activity (Ar/Ar age 48±7 ka); III generation: late Upper Pleistocene–Lower Holocene, with tephra layers correlated with the Neapolitan Yellow Tuff (~15ka); IV generation: Holocene in age. The evolution of the first three generations was controlled by Middle Pleistocene extensional tectonics, while Holocene fans do not show evidence of tectonic activity. Nevertheless, considering the moderate to highmagnitude historical seismicity of the study area, we cannot rule out that some of the recognized faults may still be active. Copyright
