We present the results of a gravity investigation conducted in the Norcia Intermountain
Basin (central Italy) in order to obtain a subsurface picture of its structural setting and
to estimate the thickness of the Quaternary infill sediments. Our survey resulted in 210
measurements, placed evenly in the whole Norcia Plain. We produced gravity anomaly
maps that show the Quaternary thickness spatial distribution within the basin and identify
buried faults affecting the bedrock in the northern basin sector. 2.5D models along close
spaced profiles were used to construct a 3D density model and a map of the bedrock top
surface elevation. Our results suggest that the northern sector of the Norcia Intermountain
Basin has been affected by a strong tectonic activity with respect to the southern sector
where the top of the bedrock is eroded and buried by a thin layer of alluvial gravels.
