![]() The fallout deposits were reconstructed using the HAZMAP computational model, which is based on a semi-analytical solution of the two-dimensional advection– diffusion–sedimentation equation for volcanic tephra. In order to assess the hazards related with tephra loading, we have considered three different eruption scenarios representative of past activity: a high-magnitude event similar to the 4.1 ka Agnano-Monte Spina eruption, a medium-magnitude event, similar to the ∼3.8 ka Astroni 6 eruption, and a low-magnitude event similar to the Averno 2 eruption. Tephra fallout associated with renewal of volca-nism at the Campi Flegrei caldera is a serious threat to the Neapolitan area. These bodies of evidence and related studies provide a direct element for an interdisciplinary approach to hazard evaluation in an active volcanic context that can also be exported to other areas. The itinerary also provides the opportunity to go on accurate guided visits to the principal archaeological sites in Campania, and to the museums, where fi ndings from the paleolithic age to the medieval age are exposed. In a relatively small area, including the Campanian Plains, with its surrounding coasts and mountains, some ten key sites, with well exposed sections, will allow us to summarize the volcanological history of the area in a trip lasting a few days. ![]() At present, a conspicuous range of geo-archaeological contexts are available and easily recognizable and allow us to better understand the effects of natural events which act with different intensities and on different time scales. ![]() In the last few years, specifi c studies focused on the stratigraphy, eruptive mechanisms, and volcano-tectonic events, have revealed key evidence for expanding our knowledge of the eruptive phenomena and their effects on the environment, human settlements, and people. Several pieces of evidence on the relations between the geographic environment, the catastrophic events, and the human context make the Campanian region a point of reference for geo-archaeological research in the world.
