Specifically, this chapter summarizes three decades of research on tsunami and storm deposit recognition, differentiation and establishing chronologies of past events. The impact and signature of the CE 1755 within coastal stratigraphic units are impressive, and its study in such a wide spatial area has provided very useful insights into tsunami dynamics. Another peculiarity addressed in this chapter is the contrast between the diverse record of tsunami or storm imprints on the Spanish part of the Gulf of Cadiz when compared with the Portuguese area. This discrepancy essentially relates to the dominance of aggrading or eroding processes favouring the preservation of deposits and also with different sediment availability during the Holocene. This allowed for a better correlation between the Spanish tsunami onshore record and its turbidite data. However, some of the deposits previously described are controversial not only sedimentologically but also because of constraints on the dates obtained. Therefore, further work is necessary on both sides of the border to establish indisputably return periods and to define a catalogue of past tsunami events affecting the southwest Iberian Peninsula during the Holocene.eninfo:eu-repo/semantics/closedAccesscapítulo de libroSedimentsTsunamiPortugalSpainExtreme wave events
