Abstract
The tsunami generated by the 1755.11.01 earthquake, as reported by coeval sources, was the major event of its kind in the North Atlantic, until nowadays. The coasts of the Iberian Peninsula and Northwest Morocco were deeply affected by that phenomenon, with tremendous impacts on the city of Lisbon. For the last 20 years, significant support was received from EU (Projects DETWS, IAM, GITEC, GITEC-TWO and BIGSETS), national projects (MATESPRO, RIFANO and RIMAR) and bi-lateral cooperation (HITS, TTR-10, SISMAR and VOLTAIRE). This allowed significant improvements on the knowledge of parameters sources and tsunami propagation. Tsunami propagation models were developed, being the simulations controlled by real data, deducted from historical reports or instrumental networks. In order to assess the considerable impacts along the Portuguese coasts, different run-up models have been used and tested. To evaluate the tsunami hazard, comprehensive studies were developed, recognizing the importance of the inter-disciplinary approach, including the study of induced continental sedimentary deposits. The location of the 1755.11.01 source has been a key question, motivating intensive marine research in the southern area of Portugal, looking for unquestionable morphological or geological evidence of fault rupture and the present-day seismic activity.
