The scope of the present work was to test the performance of Ground Penetrating Radar in the volcanic sediments, and to use this technique to investigate the archaeological ruins of one of the most important archaeological and geological sites in the world, Pompeii.<br>The preliminary results demonstrate that the GPR technique is particularly suitable in this type of volcanic terrain. In fact, the survey conducted on the archaeological area of Nola Gate has produced good results both in term of signal penetration and vertical resolution. In particular, the radar data clearly shows a series of reflectors that match well with contacts observed in the geological section, as well as hyperbolic events related to man-made structures.
