Abstract
"In the present paper we demonstrate the capability of. different remote sensing techniques to reconstruct the. evolutionary history of the lava flows on the Mt. Etna volcano. A. preliminary approach to the sites, based on aerial. photogrammetry, DEM, and topographic analyses, supports an. intense GPR (Ground Penetrating Radar) survey in several sites. with different stratigraphical characteristics. The GPR. measurements are performed with a bistatic system equipped. with both 500 and 1000 MHz antennas. The use of different. polarizations (TE, TM, Cross-Tx, and Cross-Rx) allow to extract. subsurface features information having 3D geological structure. reconstruction, electromagnetic nature information and. properties of buried reflectors.. This preliminary study highlights how the GPR technique. provides, non-destructively, useful data to study the mechanisms. of emplacement and the correlated hazard.
