Reconstructing anthropic coastal landscape of Campi Flegrei volcanic area (Southern Italy) during the Roman period from multi-technique surveys

Abstract

ABSTRACTCampi Flegrei is one of the widest and most dangerous active volcanic complexes in the Mediterranean basin, known to be affected by continuous and sudden vertical ground movements (bradyseismic crisis) that have characterized the post-calderic volcanic activity since the Late Pleistocene and particularly during the Roman period. Despite the intense volcano-tectonic processes, the area has been densely inhabited since the Greek-Roman as testified by several submerged archaeological remains here used as high-precision relative sea-level markers. By using a complex multi-technique approach made of direct, indirect morpho-acoustic and optical surveys, and stratigraphic analysis, we present a detailed reconstruction of the coastal landscape of Campi Flegrei and its surroundings between the Roman Late Republican and Early Imperial ages. The coastal scenario aims to facilitate the comprehension of how volcano-tectonic events influenced the evolution of this singular coastal landscape, and how these interfered with human activity in terms of damages and adaptation.
