Abstract
ABSTRACT This work deals with the landslides affecting the area surrounding the village of San Martino sulla Marrucina and involving the neighboring municipalities of Casacanditella and Filetto. The geological and geomorphological settings of this area are being discussed. The enclosed maps have been realized following a multidisciplinary approach, based on morphometric, geological, and geomorphological analyses and supported by air-photo interpretation, dendrochronology, and satellite SAR interferometry (InSAR). The map is organized in four sections: orography (on the upper part), geological map (on the upper right part), main geomorphological map (in the central left part, 1:7,500 scale), and multitemporal analysis (in the lower part). The aforementioned multi-temporal assessment of landslides was performed according to the geomorphological evidence-based criteria and the past ground displacement measurements were obtained by dendrochronology and InSAR. The aim of the study is to understand the evolution in time and space of this landslide area, focusing on the corresponding kinematics.
Highlights
Landslides play an important role in the landscape evolution and represent a serious hazard in many areas of the World (Aleotti & Chowdhury, 1999; Dai, Lee, & Ngai, 2002; Glade, Anderson, & Crozier, 2012)
The enclosed map shows the main features of the area and incorporates four sections, described in the following paragraphs
The study area reaches its maximum altitude in the westernmost and easternmost sectors, in correspondence of the tabular reliefs on which the principal villages rise (>400 m a.s.l.); this landscape is interrupted by the Dendalo River valley, where lower altitudes are reached
Summary
Landslides play an important role in the landscape evolution and represent a serious hazard in many areas of the World (Aleotti & Chowdhury, 1999; Dai, Lee, & Ngai, 2002; Glade, Anderson, & Crozier, 2012). These phenomena are widespread in large areas of the Italian territory (Brunetti et al, 2010; Peruccacci et al, 2017; Salvati, Bianchi, Rossi, & Guzzetti, 2010) and mainly in the Abruzzo piedmont area (Central Italy).
