Benchmarks, sediment source and hydrodynamics of the 1755 Lisbon tsunami deposi...
Font, Eric; Veiga-Pires, C.; Pozo, Manuel; Nave, Silvia; Costas, Susana; Muñoz, Francisco Ruiz; Abad, Manuel; Simões, Nuno; Duarte, SílviaStandardizing the signature of tsunami deposits has been pointed as a major limitation on the identification of paleo-tsunami deposits. This limitation majorly arises from the strongly source-dependent nature of these deposits, which in turn determines their composition and structure, and from the effect of the local morphology of the corresponding depositional environment. Here, we provide new high-resolut...
Identification of Tsunami deposits and their impact on coastal zones : a study ...
Font, Eric; Veiga-Pires, C.; Pozo, Manuel; Nave, Silvia; Costas, Susana; Muñoz, Francisco Ruiz; Abad, ManuelTsunamis are unforeseeable phenomena and therefore one of the most devastating natural disasters in terms of human and economic losses. Their impact on coastal and nearshore zones is substantial and need to be accurately evaluated to improve their prevention and management. In the last decades, numerous investigations focused on the identification of paleotsunamis in order to evaluate their frequency in the geo...

Testing rock magnetic and AMS methods in tsunami and storm-induced deposits
Font, Eric; Duarte, Sílvia; Veiga-Pires, C.; Simões, Nuno; Muñoz, Francisco Ruiz; Abad, Manuel; Pozo, Manuel; Nave, Silvia; Costas, Susana; Rebelo, LuisStorm- and tsunami-deposits are generated by similar depositional mechanisms making their discrimination hard to establish using classic sedimentologic methods. A promising approach is to use rock magnetism techniques to search for new physical benchmarks of tsunami deposits and to integrate them into a multi-disciplinary study. To test our method, we investigate the 1755 Lisbon tsunami deposit from the Boca do...
