Resistivity and Georadar Survey on the Nazca Lines

A combined resistivity and georadar survey on the Nazca Lines revealed similar subsurface structures, offering insights into desert soil weathering processes. While georadar provided fast, continuous data acquisition but with limited depth penetration (depending on frequency), resistivity imaging uncovered deeper structural features up to 3.5 meters. This study highlights the complementary strengths of these geophysical methods for investigating shallow geological formations in arid environments.
