| Sumario: | This paper summarizes the results of geological, geomorphological and morphometric analysis of 50 study areas spread between the islands of Menorca, Mallorca, Ibiza and Formentera, where large blocks appears on top of marine terraces. At distances greater than 50 m from the edge of the cliff, heights even higher than 15 m and kilometers away from any other inland escarpment, there has been registered the presence of large imbricated blocks (between 0.5 and 300 tonnes) located on broad platforms that conform some rocky shores of the Balearic Islands. The location of these areas, mostly in the southeast of the islands, coincides with the higher tsunami risk areas identified from digital models. Both the dating of the blocks, its direction of imbrication and the calculated wave heights necessary for placement, indicate transport from tsunamis generated in North Africa. |
