Tsunami risk assessment at Figueira da Foz, Portugal

The November 1st 1755 Earthquake and Tsunami were responsible for the worst natural disaster known to have occurred in Portugal, causing a high number of casualties and severe damage. Tsunami numerical simulation results that include the detailed calculation of the inundation areas at Figueira da Foz produced a maximum water level of 8m, and a local amplification at the Figueira da Foz beach. On the other hand, the numerical simulation results show that a tsunami scenario similar to the 1755 event could inundate the area up to 10 km upstream the Mondego River. By using a criterion to assess the tsunami hazard, the area has a tsunami inundation hazard between low and moderate. If the spurs and sand dunes remain intact during a tsunami event, less than 0.68 % of the resident population is at risk. However, if these structures are completely destroyed the affected population is up to 4.6%
