Abstract
The Portuguese, Spanish, and Moroccan coasts are subjected to large tsunamis generated by earthquakes with epicenters located in the Azores-Gibraltar fault. The 382 and 1755 tsunamis were generated in this area. The 1755 tsunami originated large waves causing considerable damage elsewhere along the southern coast of Portugal and Spain and northern coast of Morocco. The data already available, together with data on modern offshore seismicity, are very important to assess tsunami risk and for the establishment of environmental protection policies.
The research carried out till now shows that the A.D. 382 tsunami was generated in the same area as that of 1755. The 1761 tsunami was probably generated in a different area. The generation area of the 60 B.C. tsunami is still doubtful, and the so-called 1731 tsunami, believed to have been originated on the coast of Morocco, appears not to have occurred. The research shows also that tsunamis generated in the Azores region are rare, weak and local.
