Abstract
We present a new 1:25,000-scale geological map of the Middle Aterno Valley basin, the
epicenter of the 2009 L’Aquila MW 6.1 earthquake. This earthquake highlighted the
incomplete understanding of the geology of the area, in particular the Quaternary continental
deposits and active tectonics, which caused the Paganica fault system to be ignored by
researchers.
The map, utilizing airborne LiDAR analysis and traditional field survey approaches, is the
first example in Italy (and one of the few in Europe) that integrates high-resolution topography
in active tectonic studies. With unprecedented detail and precision on the spatial distribution of
deposits, the map of the geomorphic and tectonic features provides new insight for the
reconstruction of the Quaternary basin evolution and estimation of long-term deformation
rates for the the Paganica fault system. Detailed fault mapping of Quaternary deposits
represents an essential input for seismic hazard assessment and surface faulting hazard
evaluation.
