Abstract

The paper presents two recent examples ofapplication of Electrical Resistivity (ERT) and GroundPenetrating Radar (GPR), for reconstructing buriedsubsoil and structural geometries in two historical sitesin the city of Napoli. Both investigation sites werecharacterized by complex environmental and logisticconditions. The first case study was an ancienthypogean cavity excavated in the tuff, where theintegration between ERT and GPR allowed to identifythe depth of the soft rock below the natural andanthropic filling. The second investigation wasfinalized to detect the foundation geometry of a highmonumental bell tower resting on loose alluvial andpyroclastic soils. In both cases, the joint interpretationof ERT and GPR tests confirmed the preliminaryknowledge on the subsoil and addressed further directinvestigation aimed at the stability and safety of the twohistorical sites.
