Three georadar lines are presented in a comparison of conventional georadar processing ﬂows and ﬂows based on the gabordecon algorithm from the CREWES toolbox. The imaging goal is to map near-surface sediments above a Quaternary fault in the Piano di Castelluccio Basin in central Italy. There is a history of earthquake risk in this region and the georadar data were acquired for infrastructure planning as part of Probabilistic Seismic Hazard Assessment (PSHA) in Italy. The georadar data are used to tie reﬂection seismological fault images to the surface. We ﬁnd that the gabordecon-based ﬂow is signiﬁcantly better than the conventional ﬂow and this is likely due to Q compensation characteristics that are intrinsic to gabordecon.
