There are nine major Azores islands and several very small islands (islets), in three main groups. They extend for more than 600 km (370 mi) and lie in a northwest-southeast direction.
The archipelago is part of the Macaronesia islands.
The archipelago was settled over the centuries, mostly from mainland Portugal. Portuguese settlers came from the provinces of Algarve, Minho, Alentejo and Ribatejo, as well as Madeira.
In 1976, the Azores became the Autonomous Region of the Azores (Portuguese: Região Autónoma dos Açores), an autonomous region of Portugal.
Geography
The archipelago is in the Atlantic Ocean between 36º and 43º latitude North and between 25º and 31º longitude West. They have a very humidoceanicclimate with relatively small annual variations.
The nine islands are in three natural geographic groups, each group separated by more than 160 km (99 mi) of water. These groups are:
The eastern group also has, to the northeast of Santa Maria, a group of very small islands (islets) and reefs that are named Ilhéus das Formigas (Islets of the Ants), or just Formigas ("Ants"); these smalls islands, together with the Dollabarat reef, form the Reserva Natural do Ilhéu das Formigas.
The nine islands have a total area of 2,333 km2 (901 sq mi). Their individual areas vary between 759 km2 (293 sq mi) of the largest island (São Miguel) to 17 km2 (6.6 sq mi) of the smallest (Corvo).
Areas and highest points of the islands of the archipelago
All the islands have volcanic origins, although some, such as Santa Maria, have had no recorded activity since the islands were settled. The last volcano to erupt in the archipelago was the Capelinhos Volcano (Portuguese: Vulcão dos Capelinhos) in 1957, in the western part of the island of Faial.[4]Earthquakes are common on most of the islands.
The Azores are on place where three of the world's large tectonic plates (the North American Plate, the Eurasian Plate and the African Plate) meet.[5] The westernmost islands of the archipelago, (Corvo and Flores), are in the North American Plate, while the remaining islands are located within the region where the Eurasian plate is separated from the African Plates.[6]
The volcano Mount Pico, on the Pico island, is the highest point in Portugal, at 2,351 m (7,713 ft).
Climate
Daily maximum temperatures usually range between 15 °C (59 °F) and 25 °C (77 °F). The average annual rainfall increases from east to west, and it ranges from 700 to 1600 annual millimetres (27.6–63 in) on average, reaching 6,300 millimetres (250 in) on Mount Pico.[7]
The sea around the Azores is warmed by the Gulf Stream and sea water temperature varies from 14 °C (57 °F) to 22 °C (72 °F).[4]
When the Azores became an Autonomous Region of Portugal, the cities of Ponta Delgada, Angra and Horta were considered capital/administrative cities to the regional government: homes to the President (Ponta Delgada), the Judiciary (Angra) and the Regional Assembly (Horta).
The Azores are divided into 19 municipalities (Portuguese: concelhos); each municipality is further divided into parishes (Portuguese: freguesias), of which there is a total of 156 in all of the Azores. The municipalities, by island, are:
According to the 2011 Census, the total population in the Azores was 246,746: 121,533 men and 125,213 women. The density for the whole Archipelago is 106 persons/km2.[9]
In the agriculture sector, cattle-raising is very important. Some of the most important crops in the Azores are pineapples, grapes, potatoes, tobacco and tea. Fisheries are an important economic activity on all islands. Fishing methods are highly traditional among Azorean fishermen. Industry in the Azores is based mainly on the production of dairy products (milk, cheese) and transformation of fisheries products, such as tuna.[4]
It is tourism, however, that has been growing more in recent years. It is far less developed than those industries of its Macaronesian neighbours, Madeira and Canary Islands.[4]
