This is an open access article under the CC BY-NC-ND license (http://creativecommons.org/licenses/by-nc-nd/4.0/) Peer-review under responsibility of Marco Tanganelli and Stefania Viti Abstract The site of Villa San Marco in the archaeologica l area of Stabiae , offers a wide repertoire of degenerative situations with multiple levels of critica lity and complexity and a differentiated stratifica tion. Damage related to the known eruptive events of Vesuvius are the substratum to phenomena of deterioration activated by excavations of the Bourbon period, restoration and protection interventions that were not a lways adequate and efficient and by widespread abandonment conditions at the end of the excavation. Flora, anthropic environment, water, atmospheric agents, slope instability, seismic phenomena, combine with the technologica l characteristics of this architectura l complex, triggering degenerative processes at different speeds and intensities. A study initia ted in collaboration between the University of Florence and the Archaeologica l Park of Pompeii a ims at the knowledge of the degenera tive dynamics of the site in order to develop risk management and control systems a imed at safety of use and ma intenance. Investigations disseminated in the villa and deta iled on specific portions have begun to create a clearer picture of conservation issues. The digita l documentation of the structures has been flanked by a phase of on field investiga tion a imed a t an assessment of the degenerative phenomena, a t the ana lytica l verification and at the interpretation of the structura l instability. The research perspective is to define a multi-sca le survey approach that a llows to extract data useful for the quantification of the risk, through a systematic understanding of the vulnerabilities of the elements involved (wa lls, columns, blocks, decorated surfaces, earthen layers, etc). © 2020 The Authors.
