Geological and geomorphological analysis of a complex landslides system: the case of San Martino sulla Marruccina (Abruzzo, Central Italy)

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. ARTICLE HISTORY

Geomorphological evidence of debris flows and landslides in the Pescara del Tronto area (Sibillini Mts, Marche Region, Central Italy)

“…The mapping was performed according to the guidelines of the Geological Survey of Italy and AIGeo (Italian Association of Physical Geography and Geomorphology) (ISPRA, 2007;ISPRA & AIGEO, 2018) and was also in accordance with the literature concerning geomorphological mapping (e.g. Bozzano et al, 2020;Calista et al, 2016;Chelli et al, 2016;Gustavsson et al, 2006;Miccadei et al, 2012;Seijmonsbergen, 2013;Smith et al, 2011); the geomorphological legend used in this work was conceived based on the aforementioned Italian guidelines, in order to better represent the features of the study area.…”

“…Konovalov et al, 2019;Nowicki Jessee et al, 2020;Turner, 2018). Generally, landslide phenomena play an important role in the landscape evolution, occurring in relation to peculiar morphological, geological, and climatic characteristics, and to destabilizing effects induced by human and seismic activity (Bozzano et al, 2020;Calista et al, 2019;Carabella et al, 2019;Martino et al, 2020) and represent a serious hazard worldwide and in Italy (Aleotti & Chowdhury, 1999;Aringoli et al, 2010;Dramis et al, 2001;Farabollini et al, 1995;Glade et al, 2012;Marsala et al, 2019;Peruccacci et al, 2017;Quesada-Román et al, 2019;Tanyaş et al, 2017). Following the main event on 24 August 2016, field surveys were immediately launched, also in Pescara del Tronto area, in order to evaluate the effects of the earthquake: the focus of the survey was to detect both the effects related to the reactivation of the active faults (i.e.…”

Geomorphology-Based Analysis of Flood Critical Areas in Small Hilly Catchments for Civil Protection Purposes and Early Warning Systems: The Case of the Feltrino Stream and the Lanciano Urban Area (Abruzzo, Central Italy)

“…The main active geomorphological processes in the area are fast fluvial processes along the valley floors (flash floods), and fast soil erosion processes (surface runoff, gully, rill, and sheet erosion), as well as slow (roto-translational, complex) to fast (rock falls, flows) landslides on the valley sides. These processes affect the basins mainly during heavy rainfall events [33,[44][45][46][47][48][49][50], and flooding events affect either the main valley floors and alluvial plain areas, or the minor valleys or the anthropically modified drainage lines in urban areas.…”

Geomorphology of landslide–flood-critical areas in hilly catchments and urban areas for EWS (Feltrino Stream and Lanciano town, Abruzzo, Central Italy)

“…These methods have not been broadly implemented due to a lack of perception, and there are still many opportunities to apply these methods to urban areas and perform additional research, particularly on multi-hazard assessment and mapping (Bathrellos et al, 2017;Rosenzweig et al, 2018;Salvati et al, 2014). An evaluation of the potential areas' extent affected by floods or landslides is crucial for risk assessment and management, the management of civil protection and, consequently, the reduction of human injuries, fatalities and social-economic-structural damage (Bozzano et al, 2020;Brunetti et al, 2010;Gonçalves et al, 2015;Teng et al, 2017;Toda et al, 2017). Geomorphological mapping is an essential tool for analyzing the territories exposed to geo-hydrological hazards.…”
