The Azores Triple Junction

Coordinates: 39°26′N 29°50′W / 39.44°N 29.83°W / 39.44; -29.83 The Azores Triple Junction is a geologic triple junction where the boundaries of three tectonic plates intersect: the North American Plate, the Eurasian Plate and the African Plate. This triple junction is located along the Mid-Atlantic Ridge amidst the Azores islands, nearly due west of the Straits of Gibraltar. It is classed as a R-R-R triple junction, T type (for its shape), as it is an intersection of the Mid-Atlantic Ridge running north-south and the Terceira Rift which runs east-southeast.
