Objects of forensic investigations vary from illegally buried weapons and explosives, landmines and improvised explosive devices, drugs and weapons caches to clandestine graves of murder victims and mass genocide graves, environmental crime. Illegal excavations represent one of the main risks which affect the archaeological heritage all over the world. They cause a massive loss of artefacts but also, and above all, a loss of the cultural context, which makes the subsequent interpretation of archaeological remains very difficult. Various techniques are available for forensic crime search teams. These techniques allow for the detection of a hidden object successfully. Near-surface geophysical search methods have been dominated by ground-penetrating radar (GPR) but recently other techniques, such as electrical resistivity, magnetometric, time domain reflection have become more common. The geophysical investigation was required to investigate the presence of illegal looting in an area located 1 km north from the archaeological park of Pompeii. For this purpose combined GPR and electrical resistivity tomography (ERT) were used. Results reveal the presence of an illegal tunnel and offered the opportunity to investigate such areas not previously systematically documented.

法医地球物理调查，以调查对具有重要历史意义的遗址的非法掠夺

法医调查的对象多种多样，从非法掩埋的武器和爆炸物、地雷和简易爆炸装置、毒品和武器藏匿处到谋杀受害者的秘密坟墓和大规模种族灭绝坟墓、环境犯罪。非法挖掘是影响全世界考古遗产的主要风险之一。它们造成了大量的人工制品损失，但最重要的是，也造成了文化背景的损失，这使得随后对考古遗迹的解释变得非常困难。法医犯罪搜索团队可以使用各种技术。这些技术允许成功检测隐藏的对象。近地表地球物理搜索方法一直由探地雷达 (GPR) 主导，但最近其他技术，如电阻率、磁力、时域反射变得越来越普遍。需要进行地球物理调查，以调查庞贝考古公园以北 1 公里处是否存在非法抢劫。为此，使用了 GPR 和电阻率层析成像 (ERT) 相结合的方法。结果揭示了非法隧道的存在，并提供了调查以前未系统记录的区域的机会。
