One fact often debated is the origin of the name "Azores" used to identify the archipelago. By 1492, in the globe of Martin Behaim, the eastern and central group of islands were referred to as Insulae Azore ("Islands of the Azores"), while the islands of western group were called the Insulae Flores ("Islands of Flowers").
The lake is situated within the caldera of the Sete Cidades Massif, an ancient volcano built on various layers of ash, pyroclasts and trachyte and basaltic lavas.It is a stratovolcano constructed from alternating phases of explosive and effusive ejecta, from dominantly basaltic pre-caldera eruptions, a trachytic caldera-forming stage and a post-caldera stage consisting of alternating trachytic ...
Spain held the Azores under the Iberian Union from 1580 to 1642 (called the "Babylonian captivity" in the Azores). The Azores were the last part of the Portuguese Empire to resist Philip's reign over Portugal (Macau resisted any official recognition), until the defeat of forces loyal to the Prior of Crato with the Conquest of the Azores in 1583.
(1) "that the Azores are volcanic islands and are not the remnants of a more or less large continental mass, for they are not composed of rocks seen on the continents"; (2) "that the tachylytes dredged up from the Atlantic to the north of the Azores were in all probability formed where they are now, at the bottom of the ocean"; and
The Azores archipelago rises from Azores Plateau, which is an area of thickened oceanic crust thought to have formed over the last 20 Mya. Negative velocity S-wave anomalies have been mapped beneath the Azores in the upper 250–300 km. This has been suggested to be a signature of a plume that created the Azores Plateau. [3]
The Azores temperate mixed forests is a temperate broadleaf and mixed forests ecoregion of southwestern Europe. It encompasses the Azores archipelago in the Atlantic Ocean. These volcanic islands are an autonomous region of Portugal , and lie 1500 km west of the Portuguese mainland.
Terceira (Portuguese pronunciation: [tɨɾˈsɐjɾɐ]) is a volcanic island in the Azores archipelago, about a third of the way across the North Atlantic Ocean at a similar latitude to Portugal's capital Lisbon, and the island group is an insular part of Portugal.
Água de Pau Massif is a stratovolcanic complex, located in the central part of the island of São Miguel, in the Portuguese archipelago of the Azores.More recognizable for the Lagoa do Fogo at its centre, the volcanic complex includes centuries of geomorphological structures that include lava domes, cones and encrusted lava flows that have marked its history from, the last, 45,000 years BC.
