Abstract
In this work we use high-resolution marine geophysical techniques to investigate submerged structures located in the Amalfi port (Salerno, southern Italy). The marine surveys, still in progress, include seismic reflection investigations performed with a sub-bottom (boomer) source (SEISTEC), swath bathymetry and backscatter mapping. Ground truth control is provided by diving inspections. As reported by historical sources the submerged objects may be referred to the claimed Amalfi Sommersa; part of the medieval Amalfi port now located at depth ranging from –3 and –7 meters. In particular, sedimentological analyses of gravity cores collected in the Salerno Bay, and seismic facies interpretation of ca. 150 km of subbottom Chirp lines enabled the recognition of major sea storm events. Based on this, we assumed as an initial hypothesis that one of these events triggered a landslide phenomenon which disrupted the studied structures during high-medieval time.
