“…In fact the right angles of the paleo-river network align with the two main fault systems in whose intersection the Sarno River plain is structurally located: (i) that of Somma-Vesuvius volcanic complex which is orientated NE-SW and (ii) that of the Apennines which is NW-SE trending (Del Pezzo et al 1983;Balducci et al 1985;Marzocchi et al 1993;Bianco et al 1997;Cella et al 2007). Several hundred seismic events, mostly of volcano-tectonic type, are recorded each year in the Somma-Vesuvius area (Bianco et al 1997;Del Pezzo et al 2004). That can probably also be presumed for the time before AD 79.…”

Abstract:In this study the methodology proposed by Vogel & Märker (2010) to reconstruct the pre-AD 79 topography and paleo-environmental features of the Sarno River plain (Italy) was considerably revised and improved. The methodology is based on an extensive dataset of stratigraphical information from the entire Sarno River plain, a high-resolution present-day digital elevation model (DEM) and a classification and regression tree approach. The dataset was re-evaluated and 32 additional stratigraphical drillings were collected in areas that were not or insufficiently covered by previous stratigraphic data. Altogether, an assemblage of 1,840 drillings, containing information about the depth from the present-day surface to the pre-AD 79 paleo-surface (thickness of post-AD 79 deposits) and the character of the pre-AD 79 paleo-layer of the Sarno River plain was utilized. Moreover, an improved preprocessing of the input parameters attained a distinct progress in model performance in comparison to the previous model of Vogel & Märker (2010). Subsequently, a spatial model of the post-AD 79 deposits was generated. The modelled deposits were then used to reconstruct the pre-AD 79 topography of the Sarno River plain. Moreover, paleo-environmental and paleo-geomorphological features such as the paleo-coastline, the paleo-Sarno River and its floodplain, alluvial fans near the Tyrrhenian coast as well as abrasion terraces of historical and protohistorical coastlines were identified. This reconstruction represents a qualitative improvement of the previous work by Vogel & Märker (2010).

“…Since 1964 to nowadays the seismicity started to increase in the occurrence and in the magnitude (Giudicepietro et al, 2010), with four episodes (1978-1980, 1989-1990, 1995-1996, 1999-2000) of strong increased strain release rate, occurrence and magnitude rate (D'Auria et al, 2013). The Mesozoic basement of the volcano is displaced by both SW-and NW-dipping normal fault systems and secondarily by NE-SW and E-W faults (Bianco et al, 1998;Ventura and Vilardo, 1999;Zollo et al, 2002;Acocella and Funiciello, 2006; Figure 4). Mesoscale faults and eruptive fractures striking NW-SE, NE-SW and ENE-WSW affect volcanic units outside the Somma caldera (Rosi et al, 1987;Andronico et al, 1995;Ventura and Vilardo, 1999;D'Auria et al, 2014a, Figure 1 for a review).…”
