History The caves formation is unclear.SRAM (2013) Its genesis can be explained by the ancient lava fields that developed from fissural vents, that flowed through the valley between the larger volcanic peaks. Initially known as the ''Galeria Negra'' (''Black Gallery''), was baptised as the ''Gruta do Cavalo'' following the first exploratory investigation, when the explorers discovered the remains of a horse, which may have fallen at the entrance of the cave. Later, after 25 December 1969, with the assistance of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terceira Island
Terceira () is a volcanic island in the Azores archipelago, in the middle of the North Atlantic Ocean. It is one of the larger islands of the archipelago, with a population of 53,311 inhabitants in an area of approximately . It is the location of the Azores' oldest city, Angra do Heroísmo, the historical capital of the archipelago and UNESCO World Heritage Site; the seat of the judicial system (Supreme Court); and the main Air Force base, Base Aérea nº 4 at Lajes, with a United States Air Force detachment. The island has two main sea ports, one at Angra do Heroísmo and the other at Praia da Vitória, and a commercial airport integrated with the flight operations at Base Aérea nº 4. The Portuguese bullfight is popular on the island, coming in two variations: the traditional equestrian bullfight (in the ring) and the popular " touradas à corda" that occur in the streets. History In 1439, the first official discovery document appeared, attributing the discovery of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lava Tube
A lava tube, or pyroduct, is a natural conduit formed by flowing lava from a volcanic vent that moves beneath the hardened surface of a lava flow. If lava in the tube empties, it will leave a cave. Formation A lava tube is a type of lava cave formed when a low-viscosity lava flow develops a continuous and hard crust, which thickens and forms a roof above the still-flowing lava stream. Tubes form in one of two ways: either by the crusting over of lava channels, or from pāhoehoe flows where the lava is moving under the surface. Lava usually leaves the point of eruption in channels. These channels tend to stay very hot as their surroundings cool. This means they slowly develop walls around them as the surrounding lava cools and/or as the channel melts its way deeper. These channels can get deep enough to crust over, forming an insulating tube that keeps the lava molten and serves as a conduit for the flowing lava. These types of lava tubes tend to be closer to the lava ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basalt
Basalt (; ) is an aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the surface of a rocky planet or moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of Venus, which cover ~80% of the surface, are basaltic; the lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars. Molten basalt lava has a low viscosity due to its relatively low silica content (between 45% and 52%), resulting in rapidly moving lava flows that can spread over great areas before cooling and solidifying. Flood basalts are thick sequence ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cave
A cave or cavern is a natural void in the ground, specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word ''cave'' can refer to smaller openings such as sea caves, rock shelters, and grottos, that extend a relatively short distance into the rock and they are called ''exogene'' caves. Caves which extend further underground than the opening is wide are called ''endogene'' caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as '' speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorgan ...

Concelho
Concelho () is the Portuguese-language term for municipality, referring to the territorial subdivision in local government. In comparison, the word ''município'' () refers to the organs of State. This differentiation is still in use in Portugal and some of its former overseas provinces, but is no longer in use in Brazil following the abolition of these organs, in favour of the French prefecture system. It is similar to borough A borough is an administrative division in various English-speaking countries. In principle, the term ''borough'' designates a self-governing walled town, although in practice, official use of the term varies widely. History In the Middle ... and council.

Praia Da Vitória
Praia da Vitória (; translating as "Beach of Victory") is a municipality in the Portuguese archipelago of the Azores. With a population of 21,035 (in 2011), the second largest administrative authority on the island of Terceira, it covers an area of , that extends from the northern coast halfway into the interior. History The area of Praia, was one of the first points colonized on the island of Terceira. Praia constituted the seat of the Donatary-Captaincy of Terceira between 1456 and 1474; the island's first Captain, Jácome de Bruges along with his first lieutenant, Diogo de Teive, established their residency at this site. By 1474, the island was divided into two captaincies (Praia and Angra): the Captaincy of Praia reverted to Álvaro Martins Homem, Bruges' successor. The growth of the woad industry and export wheat market concentrated along the fertile ''Ramo Grande'' area, allowed Praia to grow rapidly. Consequently, Praia was elevated to the status of ''vila'' (comp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portugal
Portugal, officially the Portuguese Republic, In recognized minority languages of Portugal: :* mwl, República Pertuesa is a country located on the Iberian Peninsula, in Southwestern Europe, and whose territory also includes the Macaronesian archipelagos of the Azores and Madeira. It features the westernmost point in continental Europe, its mainland west and south border with the North Atlantic Ocean and in the north and east, the Portugal-Spain border, constitutes the longest uninterrupted border-line in the European Union. Its archipelagos form two autonomous regions with their own regional governments. On the mainland, Alentejo region occupies the biggest area but is one of the least densely populated regions of Europe. Lisbon is the capital and largest city by population, being also the main spot for tourists alongside Porto, the Algarve and Madeira.

Algar Do Carvão
The Algar do Carvão (''Cavern of Coal'') is an ancient lava tube or volcanic vent located in the central part of the island of Terceira in the Portuguese archipelago of the Azores. It lies within the civil parish of Porto Judeu in the municipality of Angra do Heroísmo. History The existence of the cavern had been known for a long time, but the depth and lack of ambient light, made any descent difficult, owing to the vertical descent, and delayed any real exploration.Paulo Barcelos/SIARAM (September 2010) On 26 January 1893, the first descent, ''"...with the use of a simple rope, was accomplished by Cândido Corvelo and Luis Sequeira."'' The second descent was made in 1934, by Didier Couto, who produced the first rough map of the interior. This drawing, based on visual observations alone (rather than measurements), turned out to be quite accurate. On 18 August 1963, a group of enthusiasts organized a descent using a "chair" platform suspended on a nylon line and, later, a harn ...
