Neotectonic observations along the western shore of Corsica using a scuba-diving method

Along the western coast of Corsica, 80 bathymetric profiles were drawn, from scuba-diving observations. A statistical analysis of slope breakdown bathymetry shows several standstill levels, identical to those found by Collina-Girard along the coast of Provence. Isotopic ages from the Marseilles area are Holocene age. A more selective study shows a south to north uplift: 1-2 m between Ajaccio and Sagone and 3-5 m between Sagone and Girolata. As already evidenced in the Nice area as well as in Corsica, the method proves to be highly feasible for identifying neotectonic features on vertical rocky shores.
