Airborne LiDAR survey for Monte Orsello Fault structural analysis

High-resolution airborne LiDAR (Light Detection And Ranging) products may enable precise fault scarps morphometry in active tectonic regions. In this work, we present the geomorphometric and structural analysis of the NW-SE-trending Monte Orsello Fault (MOF), one of the principal segments controlling the Campo Felice Basin in the Central Apennines of Italy. The study employs a High-Resolution Digital Elevation Model (HR-DEM) derived from the airborne LiDAR data, processed through ESRI ArcGIS Pro software, to extract key morpho-structural features and support detailed mapping of the fault system. The integrated workflow, combining HR-DEM products with high-precision field data, allowed the identification of surface fault traces, scarp geometry, and geomorphic markers. It based on approaches successfully applied to similar Apennine fault systems (Pucci et al., 2021). Moreover, through this methodology we aimed to quantify post-Last Glacial Maximum (LGM) fault throws and to investigate geometric complexity of the MOF which are critical for understanding regional tectonic evolution and seismic hazard (Schirripa Spagnolo et al., 2021). This research demonstrates how integrated geomorphometric techniques and high-resolution remote sensing data can enhance fault scarp characterization and tectonic mapping in complex terrains, contributing new insights into the seismotectonic framework of the Campo Felice Basin (Benedetti et al., 2013).
