Gran Canaria Info
Gran Canaria (Spanish pronunciation: [ɡɾaŋ kaˈna.ɾja]; originally meaning ‘Great [Island] of Dogs’) is the second most populous island of the Canary Islands, with a population of 838,397 which constitutes approximately 40% of the population of the archipelago. Located in the Atlantic Ocean about 150 kilometers (~93 miles) off the northwestern coast of Africa and about 1350 km (~838 miles) from Europe.
Gran Canaria was populated by the Canarii (Guanches), who may have arrived as early as 500 BC. The Canarii called the island Tamarán or Land of the Brave. After over a century of European (French, Portuguese…) incursions and attempts at conquest, the island was conquered on April 29, 1483, after a campaign that lasted 5 years, by the Kingdom of Castile, with the support of Queen Isabella I, a conquest which turned out to be an important step towards the expansion of the unified Spain.
The capital city of Las Palmas was founded on June 24, 1478, under the name “Real de Las Palmas”, by Juan Rejón, head of the invading Castilian army. In 1492,Christopher Columbus anchored in the Port of Las Palmas (and spent some time on the island) on his first trip to the Americas. Las Palmas is, jointly with Santa Cruz de Tenerife, the capital of the autonomous community of the Canary Islands.
Gran Canaria is located southeast of Tenerife and west of Fuerteventura. The island is of volcanic origin, mostly made of fissure vents. Gran Canaria’s surface area is 1,560 km² and its maximum altitude is 1,949 meters (Pico de Las Nieves). It has a round shape, with a diameter of approximately 50 km.
Geology
About 80% of the volume of the island was formed during the Miocene period, between 14 and 9 million years ago. This is called the “Old Cycle” and is estimated to have lasted some 200,000 years and have emitted about 1000 km3, mostly of fissural alkali basalt. This cycle continued with the emission of trachytes, phonolites and peralkaline rocks. This period was followed by one of erosion, which lasted some 4 million years.
A second cycle of volcanic eruptions, known as the “Roque Nublo cycle”, took place between 4.5 and 3.4 million years ago. This shorter cycle emitted about 100 km3. Most of the inland peaks were formed by erosion from these materials. This period also started with fissural basalts, but ended with violent eruptions of pyroclastic flows. Some phonolitic features, like the Risco Blanco, were also formed in its last stages.
The third or recent cycle is held to have started some 2.8 million years ago and is considered to be still active. The last eruptions are held to have occurred some 3500 years ago.
The changes in volume and, therefore, weight of the island have also caused the island to rise above the previous sea level during erosive periods and to sink during eruptive periods. Some of these “fossil beaches” can be seen in the cliff faces of the more eroded northern coast.
Climate
Gran Canaria is noted for its rich variety of micro climates. Generally speaking though, the average daytime high ranges from 20°C in winter, to 26°C in summer. Some cool nights occur in winter, but lows below 10°C are unknown near the coast. Inland the climate is still mild but mountainous areas see the occasional frost or snow. Annual rainfall averages 228 mm, most of this falling in the cooler months, with July, August and September normally rainless. Rainfall is unevenly distributed through the island with some areas being much drier than others. Cloud cover and sunshine is often quite variable during the cooler months, and there can be several rather cloudy days at times in winter. Summers are generally quite sunny however, with the south of the island being most favoured.
Nearly half of the island territory – 667 km² (42,7% of island), is under protection from theRed Canaria de Espacios Naturales Protegidos (Canary Islands Network for Naturally Protected Areas). Of the 146 protected sites under control of network in the Canary Islands archipelago, a total of 33 are located in Gran Canaria, the second most protected island in the group. There are seven different categories of protection: six nature reserves: El Brezal, Azuaje, Los Tilos de Moya, Los Marteles, Las Dunas de Maspalomas and Güigüi (total 7,153.1 ha); two integral nature reserves: Inagua and Barranco Oscuro (total 3,955,5 ha); two natural parks: Tamadaba and Pilancones (total 13,333 ha), two rural parks: Nublo and Doramas (total 29,893.4 ha), ten natural monuments: Amagro, Bandama, Montañón Negro, Roque de Aguayro, Tauro, Arinaga, Barranco de Guayadeque, Riscos de Tirajana, Roque Nublo and Barranco del Draguillo (total 5,264.9 ha), seven protected landscapes: La Isleta (in the capital Las Palmas de Gran Canaria), Pino Santo, Tafira, Las Cumbres, Lomo Magullo, Fataga and Montaña de Agüimes (total 12,680.9 ha); four sites of scientific interest: Jinámar, Tufia, Roque de Gando and Juncalillo del Sur (total 276.2 ha).
