On January 13th 2012, the cruise ship Costa Concordia was stranded in front of Punta Gabbianara, in the North-Western coast of Giglio Island (Tuscany, Italy). To support the Search and Rescue (SaR) and removal operations, a sophisticated monitoring system was implemented. The Terrestrial Laser Scanner device was integrated in a ground-based monitoring system network, to detect the vessel displacements. The location of this instrument permitted to perform a semiautomatic geomechanical survey of the observed portion of Punta Gabbianara rock mass. Furthermore, a traditional geomechanical field survey was performed to integrate the results of the semiautomatic processing.
