Boulders of 2 coastal areas (Cape Skalas in southern Lakonia, Peloponnese; Cape Gerogombos on Paliki Peninsula in western Greece were surveyed within their topographical context using a laser scanner in combination with a DGPS. 3D reconstruction
allows the determination of highly accurate volumetric data, as well as the extraction of further parameters, such as elevation above sea level, inclination and distance to the sea for each boulder. The results show that terrestrial laser scanning
the common method in scientific studies on boulder dislocation. The AA. found that volume data based on axes measurements together with density approximations result in a considerable overestimation of the mass of dislocated boulders.
to 2011. A Riegl LMS-Z420 i laser scanner was used in combination with a DGPS. Moreover, TLS-based volume and mass data of dislocated boulders encountered at several sites were incorporated into tsunami wave transport equations and compared to buoy data
. High-energy dislocated boulders showed no movement during the monitoring period. Thus, it is assumed that they were been transported inland by extreme events, which were stronger than the average coastal dynamics between 2009 and 2011. Both
the orientation and the spatial distribution pattern of the dislocated boulders match with observations of boulders dislocated by tsunami impact.
