| Abstract |
Few studies have attempted to ascertain the tsunamigenic origin of boulder deposits in coastal zones. One critical problem is related to the interpretation of the stratigraphical context and therefore the absolute dating of the event. Moreover, extreme storms and hurricanes may be capable of boulder transport, so that the identification of the processes responsible for the deposition of boulders in coastal zones contains some pitfalls. For the purpose, the boulder movement and transport capacity of extreme storm and hurricane waves are discussed here, and it is demonstrated that parameters such as the altitude of boulder accumulation, the distance to the shoreline and/or simply the weight of the boulders can unambiguously point to a tsunami as the transport mechanism. Examples are given for both tsunami and hurricane boulder transport and the tsunamigenic origin of coarse debris as well as for strong tsunami within the late Holocene with boulder dislocation worldwide. |
