Geological and geophysical characterization of the southeastern side of the High Agri Valley (southern Apennines, Italy)

Abstract

Abstract. In the frame of a national project funded by Eni S.p.A. and developed by three institutes of the National Research Council (the Institute of Methodologies for Environmental Analysis, the Institute of Research for Hydrogeological Protection and the Institute for Electromagnetic Sensing of the Environment), a multidisciplinary approach based on the integration of satellite, aero-photogrammetric and in situ geophysical techniques was applied to investigate an area located in the Montemurro territory in the southeastern sector of the High Agri Valley (Basilicata Region, southern Italy). This paper reports the results obtained by the joint analysis of in situ geophysical surveys, aerial photos interpretation, morphotectonic investigation, geological field survey and borehole data. The joint analysis of different data allowed us (1) to show the shallow geological and structural setting, (2) to detect the geometry of the different lithological units and their mechanical and dynamical properties, (3) to image a previously unmapped fault beneath suspected scarps/warps and (4) to characterize the geometry of an active landslide affecting the study area.

Geometry and Structure of a Fault‐Bounded Extensional Basin by Integrating Geophysical Surveys and Seismic Anisotropy Across the 30 October 2016 Mw 6.5 Earthquake Fault (Central Italy): The Pian Grande di Castelluccio Basin

“…Electrical resistivity tomography (ERT) is suitable to provide high‐resolution images of the very near surface, particularly in correspondence of fault zones (Giocoli et al, ; Park & Wernicke, ; Unsworth et al, ). On December 2016 and March 2017 we acquired three 630‐m‐long ERT profiles (T1, T2, and P1, Figure ) running WSW‐ENE and nearly orthogonal to the main basin bounding structures (F1 and F3) as well as to the trace of the Norcia earthquake surface ruptures (VF).…”

“…), ERT survey was carried out. In recent years, this technique has been increasingly applied in seismotectonic and geomorphological studies (Giocoli et al 2008;Balasco et al 2011), to investigate the geological and structural setting (Giocoli et al 2015) and to study landslides (Perrone et al 2014), ERT is a fast, non-invasive and low-cost geophysical method, widely applied to obtain high-resolution 2-D images of the subsurface resistivity pattern (Mucciarelli et al 2011;Moscatelli et al 2014;Stabile et al 2014). The ERT surveys were performed along four profiles by means of a Syscal R2 (Iris Instruments) resistivity metre, coupled with a multielectrode acquisition system (36, 44 or 48 electrodes).…”
