“…Along the coast of Vendicari, 40 km south of Siracusa ( Fig. 1(a)), Barbano et al (2010) discovered a boulder field and isolated boulders related to different tsunami events. Moreover, tsunami impact deposits related to the 1693 event and other tsunami and storm deposits were found preserved within a ria-type rocky coastal setting at the bottom of the channel harbour of Ognina, 20 km south of Siracusa (Scicchitano et al, 2010).…”

“…In the boulder accumulation process, is the impacting wave height more important compared to the wave length and to the wave period? Different theories have been proposed in the recent time, but the final reply is still far away (Nott, 2003;Goto et al, 2007Goto et al, , 2009bGoto et al, , 2010bHansom et al, 2008;Imamura et al, 2008;Pignatelli et al, 2009;Barbano et al, 2010). The more easy reply is that if a wave can be described by height, length and period, the best way to evaluate its impact on a rocky coast should consider these parameters all together.…”

The coastline of the Maddalena peninsula (south-eastern Sicily, Italy) is characterised by the occurrence of a boulder field associated to an extended soil stripping area and by a gravel/sandy berm. The accumulation of the boulders has been mostly correlated to the impact of the December 28, 1908 tsunami wave. The use of Terrestrial Laser Scanner survey techniques, associated to Differential Global Position System determinations, permits to obtain new data for the assessment of tsunami impact on this coastal area. The computing of the surveyed data using the most recent equations is a useful tool in order to estimate the theoretic inundation limit and to reconstruct its variability in function of the boulders size and of the coastal topography. Moreover, the entire new data set allows to confirm that the hypothesis of the tsunami impact is the most reasonable to explain the occurrence of boulders weighing up to 50 tons on the Maddalena peninsula.

“…Recent hydrodynamic theories tried to put in relation boulders and coastal features to the wave responsible for their accumulation developing mathematical formulas. Starting from the boulders size and shape, knowing the local waveclimate, it should be possible to discriminate between storm and tsunami inland scattering (Nott, 1997(Nott, , 2003Noormets et al, 2002Noormets et al, , 2004Pignatelli et al, 2009;2010a,b;Imamura et al, 2008;Barbano et al, 2010).…”

“…While there is no ambiguity for observations of recent tsunamis (Goff et al, 2006;Goto et al, 2007), large boulder accumulations may be associated with historic and prehistoric events related to tsunamis (Nott, 2000;Mastronuzzi and Sansò, 2000;Williams and Hall, 2004;Mastronuzzi et al, 2007;Maouche et al, 2009;Paris et al, 2009). Nevertheless, we cannot rule out the possibility of transport by storms (Barabano et al, 2010), and some recent case studies show the role of storm waves in forming boulder accumulations worldwide (Noormets et al, 2002;Nott, 2004;Goto et al, 2009Goto et al, , 2011Suanez et al, 2009;Etienne and Paris, 2010).…”

Abstract. An accumulation of boulders was recently discovered along the rocky coast of the Gulf of Fos located in Provence, in an area exposed to a south-westerly wave regime. The coast around this locality forms the western extremity of the calcareous Nerthe range between Marseille and the Rhône Delta. Several mega blocks are scattered to a distance of 30 m behind the coast line. The largest block (33.5 tonnes) has been transported about 39 m inland, up to about 2 m a.s.l. On the Mediterranean coast, the origin of such blocks is often attributed to tsunami-generated waves, but in the case examined here, although the origin is unclear, the differences in surface state between boulders indicates several events generated by south-westerly storms. Radiocarbon dating on several different shells collected from seven different boulders yields a wide dispersion of ages ranging from 4000 BP to the Modern Period. The differences in surface appearance, as well as the differences of fauna conservation and surface coloration, in some cases in a very fresh state, along with the dispersion of radiocarbon ages, suggest that historic storm events have affected these megablocks.
