Geographical Area
The Azores is an oceanic archipelago composed of nine volcanic islands and several islets situated on the Azores Plateau raised from the Mid-Atlantic Ridge. The islands are found in a tectonic triple junction where the American, Eurasian and African platforms intersect. The seafloor surrounding the islands is characterized by a diverse topography comprising island slopes, seamounts, deep fracture zones, trenches, a considerable extension of the Mid-Atlantic Ridge (MAR) and abyssal plains exceeding 5,000m depth.
Portugal’s marine jurisdiction around the islands encompasses an Exclusive Economic Zone of almost 1 million km2 of which about 99% is deeper than 3000 m.
