Caldeira Volcano
The Caldeira Volcano (Portuguese: ) is the highest mountain, massive stratovolcano and the largest geomorphological structure that forms the island of Faial. The mountain's highest point, Cabeço Gordo, reaches above sea level. One of the most notable features of this volcano is its two kilometer wide caldera, that is in depth below the crater rim. History Along the western edge of the Ribeirinha Volcano, the Central Volcanic Complex formed about 410,000 years ago, along with several structures that arose from tectonics. Evidence of this process has not been preserved due to subsistence, but it is generally believed that two formations (an Upper and Lower group) reflecting a geochemical variation that occurred about 16,000 years ago. The Lower group (from 410,000 years ago), was marked by the predominance of a Hawaiian/Strombolian eruptive process, that was composed of basaltic and benmoreitic rocks. The secondary, Upper group, was a highly explosive period (sub-Plinian in ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Faial Island
Faial Island (), also known in English as Fayal, is a Portugal, Portuguese island of the Central Group (Portuguese: ''Grupo Central'') of the Azores. The Capelinhos Volcano, the westernmost point of the island, may be considered the westernmost point of Europe, if the Monchique Islet, near Flores Island (Azores), Flores Island, is considered part of North America, for it sits on the North American Plate. Its largest town is Horta, Azores, Horta. With its nearest neighbours, Pico Island, Pico (east across the channel) and São Jorge Island, São Jorge (northeast across the channel), it forms an area commonly known as the ''Triângulo'' (English: ''Triangle''). The island has also been referred to as the Ilha Azul (English: ''Blue Island''), derived from the writings of Portuguese poet Raul Brandão, due to the large quantity of hydrangeas that bloom during the summer months: History During a period of medieval legends and unsubstantiated stories of mystical lands, the island ...

Volcanic Crater
A volcanic crater is an approximately circular depression in the ground caused by Volcano, volcanic activity. It is typically a bowl-shaped feature containing one or more vents. During Types of volcanic eruptions, volcanic eruptions, molten magma and volcanic gases rise from an underground magma chamber, through a conduit, until they reach the crater's vent, from where the gases escape into the atmosphere and the magma is erupted as lava. A volcanic crater can be of large dimensions, and sometimes of great depth. During certain types of explosive eruptions, a volcano's magma chamber may empty enough for an area above it to subside, forming a type of larger depression known as a caldera. Geomorphology In most volcanoes, the crater is situated at the top of a mountain formed from the erupted volcanic deposits such as lava flows and tephra. Volcanoes that terminate in such a summit crater are usually of a conical form. Other volcanic craters may be found on the flanks of volcanoe ...

Stratovolcano
A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava and tephra. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and periodic intervals of explosive eruptions and effusive eruptions, although some have collapsed summit craters called calderas. The lava flowing from stratovolcanoes typically cools and hardens before spreading far, due to high viscosity. The magma forming this lava is often felsic, having high-to-intermediate levels of silica (as in rhyolite, dacite, or andesite), with lesser amounts of less-viscous mafic magma. Extensive felsic lava flows are uncommon, but have travelled as far as . Stratovolcanoes are sometimes called composite volcanoes because of their composite stratified structure, built up from sequential outpourings of erupted materials. They are among the most common types of volcanoes, in contrast to the less common shield volca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portuguese Language
Portuguese ( or, in full, ) is a western Romance language of the Indo-European language family, originating in the Iberian Peninsula of Europe. It is an official language of Portugal, Brazil, Cape Verde, Angola, Mozambique, Guinea-Bissau and São Tomé and Príncipe, while having co-official language status in East Timor, Equatorial Guinea, and Macau. A Portuguese-speaking person or nation is referred to as " Lusophone" (). As the result of expansion during colonial times, a cultural presence of Portuguese speakers is also found around the world. Portuguese is part of the Ibero-Romance group that evolved from several dialects of Vulgar Latin in the medieval Kingdom of Galicia and the County of Portugal, and has kept some Celtic phonology in its lexicon. With approximately 250 million native speakers and 24 million L2 (second language) speakers, Portuguese has approximately 274 million total speakers. It is usually listed as the sixth-most spoken language, the third-most sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cabeço Gordo
Cabeço Gordo (Portuguese for "fat mound") is the highest point in the island of Faial, measuring above sea level. Located on the southern rim of the Caldeira Volcano, on a clear day, most of the islands of the central group of the Azores are visible: Pico, São Jorge, and Graciosa Graciosa Island () (literally "graceful" or "enchanting" in Portuguese) is referred to as the ''White Island'', the northernmost of the Central Group of islands in the Azores.

Caldera
A caldera ( ) is a large cauldron-like hollow that forms shortly after the emptying of a magma chamber in a volcano eruption. When large volumes of magma are erupted over a short time, structural support for the rock above the magma chamber is gone. The ground surface then collapses into the emptied or partially emptied magma chamber, leaving a large depression at the surface (from one to dozens of kilometers in diameter). Although sometimes described as a Volcanic crater, crater, the feature is actually a type of sinkhole, as it is formed through subsidence and collapse rather than an explosion or impact. Compared to the thousands of volcanic eruptions that occur each century, the formation of a caldera is a rare event, occurring only a few times per century. Only seven caldera-forming collapses are known to have occurred between 1911 and 2016. More recently, a caldera collapse occurred at Kīlauea, Hawaii in 2018.

Capelinhos
The Capelinhos (from Capelo + ''-inhos'' diminutive, which literally means "little cape") is a monogenetic volcano located on the western coast of Faial Island in the Azores. It is part of the larger volcanic complex of Capelo, which includes 20 scoria cones and lava fields that are aligned west-northwest to east-southeast from the Caldeira Volcano caldera. Although the name "Capelinhos" is associated with the volcano, it technically refers to the western cape of the parish of Capelo. It can be considered the westernmost point of Europe; there are more westerly islands in the Azores archipelago but they lie on the North American Plate. A volcanic eruption lasted for 13 months, from September 27, 1957 until October 24, 1958, which may have been two overlapping volcanic eruptions. While enlarging the land by 2.4 km², it spawned 300 seismic events, hurled ash 1 km, destroyed 300 houses in the parishes of Capelo and Praia do Norte and caused the evacuation of 2,000 people ...
