Description:
A high-resolution morphological and geological inspection was carried out on the Palinuro Bank (39
300N, 14 480E), a volcanic complex made by several, coalescent volcanic features located on the Campanian
continental slope (Eastern Tyrrhenian Sea, Italy). A shallow ( 84 m asl) volcanic edifice, characterized
by a flat top modelled surface, is present on its central sector. The use of a very high-resolution
Digital Terrain Model allowed recognition of the presence of relict morphologies (perhaps notches/inner
margins) related to the past sea-level still-stands. Three depth levels of paleo-shorelines markers are
located at 90 m, 100 m, and 123 m, respectively. In addiction, the truncated shape of the cone itself,
located between 84 m and 130 m, could be interpreted as a tilted marine terrace. Breaks in slope
produced by terrace landforms caused oversteepening that could have triggered lateral collapses both on
the northern and southern flanks of the Bank, as suggested by the presence of steep slopes (25e40 ) and
indicated by acoustic facies on chirp high-resolution mono-channel seismic profiles. The results allow
further hypotheses on vertical displacement between the western sector of the Palinuro Bank, where
caldera shapes are present, and the central sector, made by shallower volcanic cones. These two sectors
also differ in terms of magnetic properties.
