In a lecture held at Iscia, Fernando Rebelo, an investigator, warned of the dangers of this and other natural disasters in the Alentejo, Algarve and the Azores.
The risk of tsunami, typhoons and storms at sea unfold a risk of coastal flooding in Portugal and are ignored by the official map of risks published in 2006, annexed to the National Policy and Planning, said the former dean of the University of Coimbra, Fernando Rebelo, during the VII National Meeting on Risks and First Forum on Risks and Security of the Territory, held at the Institute of Information Sciences and Administration. A warning that he considers of vital importance, since "the risk is higher in the south, particularly on the west coast of Alentejo and Algarve, in the rest of the country is medium or small, but there is no zero risk," he said. The professor stressed that the origin of tsunamis is in earthquakes, but it is not the only one, he also referred "other causes" like volcanic eruptions and landslides. He even observed, "early in the study of tectonic plates appeared before a rift in the Iberian Peninsula (fracture zone, accompanied by in opposite directions away from the surface), where he had knowledge of many underwater eruptions, noting:" the Azores were born that way. "
The academic reinforced this argument adding that "there have been volcanoes running that were not already active for 500 years, to conclude that there is no guarantee that a volcano will not start operations in this area, especially since, off the island of Terceira the submarine volcano Serreta was erupting between 1998 and 2001, limiting the passage of ships and aircraft. " Further, it cites a research study led by geologist Victor Forjaz, which points to the possibility of the existence of the Eurasian plate, in the area of the Azores, with serious risks to San Miguel. He also said that recent studies admit the possibility of a subduction zone (area of convergence of tectonic plates, where one of them sneaks beneath the other) very close to Cadiz, a situation which he called "scary, especially if it was responsible for the tremor on land in Granada, which occurred in 2010”.
