Furna De Água
Furna de Água is a cave system located in the municipality of Angra do Heroísmo, on the island of Terceira in the Portuguese archipelago of the Azores. The long volcanic lava tube A lava tube, more rarely called a pyroduct, is a 'roofed conduit through which molten lava travels away from its vent'. If lava in the tube drains out, it will leave an empty cave. Lava tubes are common in low-viscosity volcanic systems. La ..., is one of the main sources of fresh water on the island, due to the presence of several springs within the cave. Although known since 1838 (and perhaps earlier), Furna de Água only began to be prospected and used in the mid-20th century. History Its name originated from the existence of an abundance of springs in its interior, many of which became known since 1838.SRAM (2013) At that time, the famed Terceirense historian Francisco Ferreira Drummond was local representative in Vila de São Sebastião, and he investigated the stories about the Furna ...

Terceira Island
Terceira () 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, with the island group forming an insular part of Portugal. It is one of the larger islands of the archipelago, with a population of 53,311 inhabitants in an area of approximately . Terceira 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 insular Portuguese Air Force base, Lajes Field, Base Aérea nº 4 at Lajes, with a United States Air Force detachment. Terceira 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 Lajes Field, Base Aérea nº 4. The Portuguese bullfight is popular on the island, coming in two variations: the traditional equestrian bullfight ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Azores
The Azores ( , , ; , ), officially the Autonomous Region of the Azores (), is one of the two autonomous regions of Portugal (along with Madeira). It is an archipelago composed of nine volcanic islands in the Macaronesia region of the North Atlantic Ocean, about west of Lisbon, about northwest of Morocco, about southeast of Newfoundland, Canada, and the same distance southwest of Cork, Ireland. Its main industries are agriculture, dairy farming, livestock, fishing, and tourism, which has become a major service activity in the region. In the 20th century and to some extent into the 21st, they have served as a waypoint for refueling aircraft flying between Europe and North America. The government of the Azores employs a large percentage of the population directly or indirectly in the service and tertiary sectors. The largest city of the Azores is Ponta Delgada. The culture, dialect, cuisine, and traditions of the Azorean islands vary considerably, because these remote island ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lava Tube
A lava tube, more rarely called a pyroduct, is a 'roofed conduit through which molten lava travels away from its vent'. If lava in the tube drains out, it will leave an empty cave. Lava tubes are common in low-viscosity volcanic systems. Lava tubes are important as they are able to transport molten lava much further away from the eruptive vent than lava channels. A tube-forming lava flow can emplace on longer distance due to the presence of a solid crust protecting the molten lava from atmospheric cooling. Lava tubes are often considered when preparing hazard maps or managing an eruptive crisis. 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. Three main formation mechanisms have been described: (1) roofing over a lava channel, (2) pāhoehoe lobe extension or (3) lava flow inflation. # When it erupts from a vent, lava usually flow ...

Basalt
Basalt (; ) is an aphanite, 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 planetary surface, surface of a terrestrial planet, rocky planet or natural satellite, 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 volcanism on Venus, Venus, which cover ~80% of the surface, are basaltic; the lunar mare, 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 flo ...

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 and council. History After the civil parish (), the Portuguese ''concelho'' is the most stable territorial subdivision within the country, with over 900 years of history. Founded in the royal charters attributed to parcels and territorial enclaves, in order to establish a presence by the Crown, rather than personal fiefdoms of the nobility and aristocracy. This municipal institution changed throughout history: many were abolished and reconstituted based on the political necessity; first they were subject to the specifics of each charter (which varied bas ...

Spring (hydrosphere)
A spring is a natural exit point at which groundwater emerges from an aquifer and flows across the ground surface as surface water. It is a component of the hydrosphere, as well as a part of the water cycle. Springs have long been important for humans as a source of fresh water, especially in arid regions which have relatively little annual rainfall. Springs are driven out onto the surface by various natural forces, such as gravity and Hydrostatics#Hydrostatic pressure, hydrostatic pressure. A spring produced by the emergence of Geothermal activity, geothermally heated groundwater is known as a hot spring. The yield (hydrology), yield of spring water varies widely from a volumetric flow rate of nearly zero to more than for the biggest springs. Formation Springs are formed when groundwater flows onto the surface. This typically happens when the water table reaches above the surface level, or if the terrain depression (geology), depresses sharply. Springs may also be formed ...

Duke Of Terceira Garden
Duke of Terceira Garden () is a manicured garden in the Centro Histórico de Angra do Heroísmo, historical centre of Angra do Heroísmo, on the island of Terceira in the Portugal, Portuguese archipelago of the Azores. One of the classic gardens emblematic of the Romantic period of Portuguese history, it is part of the municipal gardens of the city of Angra (located within the Freguesia (Portugal), civil parish of Nossa Senhora da Conceição (Angra do Heroísmo), Nossa Senhora da Conceição. History Urban growth in the 19th century, brought to Angra the notion of the public garden and green-spaces to the urban zones. What developed in the municipality was the concept of public footpaths or walkways, where events were usually organized. The municipal council of Angra, therefore, acquired in 1864 the useful area known as ''Sítio Fagundes'', purchasing the building, registered in 1872 in the ''Conservatória do Registo Predial'', to construct a public space. The area was part of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
