Stromboli
Stromboli ( , ; scn, Struògnuli ) is an island in the Tyrrhenian Sea, off the north coast of Sicily, containing Mount Stromboli, one of the four active volcanoes in Italy. It is one of the eight Aeolian Islands, a volcanic arc north of Sicily. Strabo writes that people believed that this is where Aeolus lived. The island, with an area of , represents the upper third of the volcano. Its population was about 500 . The volcano has erupted many times and is constantly active with minor eruptions, often visible from many points on the island and from the surrounding sea, giving rise to the island's nickname "Lighthouse of the Mediterranean". Etymology Its name is derived from the Ancient Greek name , (Στρογγύλη) which was derived from (, "round"), after the volcano's round, conical appearance when seen from a distance.

Types Of Volcanic Eruptions
Several types of volcanic eruptions—during which lava, tephra (ash, lapilli, volcanic bombs and volcanic blocks), and assorted gases are expelled from a volcanic vent or fissure—have been distinguished by volcanologists. These are often named after famous volcanoes where that type of behavior has been observed. Some volcanoes may exhibit only one characteristic type of eruption during a period of activity, while others may display an entire sequence of types all in one eruptive series. There are three different types of eruptions: * Magmatic eruptions are the most well-observed type of eruption. They involve the decompression of gas within magma that propels it forward. * Phreatic eruptions are driven by the superheating of steam due to the close proximity of magma. This type exhibits no magmatic release, instead causing the granulation of existing rock. * Phreatomagmatic eruptions are driven by the direct interaction of magma and water, as opposed to phreatic erup ...

Volcanology Of Italy
The volcanism of Italy is due chiefly to the presence, a short distance to the south, of the boundary between the Eurasian Plate and the African Plate. Italy is a volcanically active country, containing the only active volcanoes in mainland Europe (while volcanic islands are also present in Greece, in the volcanic arc of the southern Aegean). The lava erupted by Italy's volcanoes is thought to result from the subduction and melting of one plate below another. Three main clusters of volcanism exist: a line of volcanic centres running northwest along the central part of the Italian mainland (see: Campanian volcanic arc); a cluster northeast of Sicily in the Aeolian Islands; and a cluster southwest of Sicily around the island of Pantelleria, in the Mediterranean's Strait of Sicily. Sardinia has had a totally separate geological history from that of the rest of Italy, where several cycles of volcanic activity occurred, the last of which ended at the beginning of the Pleistocene ...

Strombolicchio
Strombolicchio () is a sea stack of volcanic origin to the northeast of the island of Stromboli in the Aeolian Islands of Italy. Its name in the Sicilian language, ''Struognulicchiu,'' means ''Little Stromboli''. Geology Geologically, Strombolicchio is a volcanic plug or spine of extremely hard compacted basalt resistant to erosion, and is the remnant of the original volcano from which the island of Stromboli was built up. Eruptions at this site ceased approximately 200,000 years ago. Since then the volcanic activity has moved about to the southwest. It is the only remnant above sea level of an otherwise submarine platform that extends between it and the main island. Flora and fauna Strombolicchio hosts some very rare species of flora and fauna and has been declared a natural reserve, with severe restrictions on access. '' Bassia saxicola'', for example, an endangered flower at risk of extinction, is otherwise present in only a few hundred specimens on the island of Capri. '' ...

Sciara Del Fuoco
Sciara del Fuoco is a Scree, talus scree or depression located on Stromboli, Stromboli Island in Italy. It runs along the island's northern flank and is bounded by two ridges. It now serves as a major tourist attraction on the island. Formation Sciara del Fuoco was formed as a result of a sector collapse around 5,000 years ago. Due to this, it is sometimes referred to as a scar. It was formed by lava, lapilli and Incandescence, incandescent waste. References Volcanoes of Italy Stromboli {{Europe-geologic-formation-stub ...

Aeolian Islands
The Aeolian Islands ( ; it, Isole Eolie ; scn, Ìsuli Eoli), sometimes referred to as the Lipari Islands or Lipari group ( , ) after their largest island, are a volcanic archipelago in the Tyrrhenian Sea north of Sicily, said to be named after Aeolus, the mythical ruler of the winds. The islands' inhabitants are known as Aeolians ( it, Eoliani, links=no). The islands had a permanent population of 14,224 at the 2011 census; the latest official estimate is 15,419 as of 1 January 2019. The Aeolian Islands are a popular tourist destination in the summer and attract up to 600,000 visitors annually. There are seven significant islands: Lipari, Vulcano, Salina, Stromboli, Filicudi, Alicudi and Panarea, and a set of minor islands and rocks. Geography The ''Lipari Islands'' are 30 km and 80 km off the north coast of Sicily in the Tyrrhenian Sea. Vulcano is located closest to the Sicilian coast. Lipari and Salina follow to the north, Filicudi and Alicudi to the west, and Pan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanic Plug
A volcanic plug, also called a volcanic neck or lava neck, is a volcanic object created when magma hardens within a vent on an active volcano. When present, a plug can cause an extreme build-up of high gas pressure if rising volatile-charged magma is trapped beneath it, and this can sometimes lead to an explosive eruption. In a plinian eruption the plug is destroyed and ash is ejected. Glacial erosion can lead to exposure of the plug on one side, while a long slope of material remains on the opposite side. Such landforms are called crag and tail. If a plug is preserved, erosion may remove the surrounding rock while the erosion-resistant plug remains, producing a distinctive upstanding landform. Examples of volcanic plugs Africa Near the village of Rhumsiki in the Far North Province of Cameroon, Kapsiki Peak is an example of a volcanic plug and is one of the most photographed parts of the Mandara Mountains. Spectacular volcanic plugs are present in the center of La Gomer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tyrrhenian Sea
The Tyrrhenian Sea (; it, Mar Tirreno , french: Mer Tyrrhénienne , sc, Mare Tirrenu, co, Mari Tirrenu, scn, Mari Tirrenu, nap, Mare Tirreno) is part of the Mediterranean Sea off the western coast of Italy. It is named for the Tyrrhenian people identified with the Etruscans of Italy. Geography The sea is bounded by the islands of Corsica and Sardinia (to the west), the Italian Peninsula (regions of Tuscany, Lazio, Campania, Basilicata, and Calabria) to the north and east, and the island of Sicily (to the south). The Tyrrhenian Sea also includes a number of smaller islands like Capri, Elba, Ischia, and Ustica. The maximum depth of the sea is . The Tyrrhenian Sea is situated near where the African and Eurasian Plates meet; therefore mountain chains and active volcanoes such as Mount Marsili are found in its depths. The eight Aeolian Islands and Ustica are located in the southern part of the sea, north of Sicily. Extent The International Hydrographic Organization define ...

Ginostra (village)
Ginostra is a small village set in a natural amphitheater in the southwest of the island of Stromboli, north to Sicily, southern Italy. The village has about forty permanent residents, and fewer than a dozen mules and donkeys. The tiny village is surrounded by olive, lemon, caper and prickly pear. Structures consists of white stucco buildings similar to those found in other Mediterranean islands such as Santorini. Facilities Ginostra can only be reached by boat due to a lack of roads or trails on the island. Boats dock at the new pier, opened in December 2004. Until February 28, 2004, the village had no electricity or running water. Electricity is now supplied by the photovoltaic panels and diesel generators located near the marina, and running water comes from rainwater collected in wells, and is supplemented by ships from Naples. Despite the new electrical grid, there is no street lighting. The village has a single telephone booth. Life in the village revolves around the pl ...

Journey To The Center Of The Earth
''Journey to the Center of the Earth'' (french: Voyage au centre de la Terre), also translated with the variant titles ''A Journey to the Centre of the Earth'' and ''A Journey into the Interior of the Earth'', is a classic science fiction novel by Jules Verne. It was first published in French in 1864, then reissued in 1867 in a revised and expanded edition. Professor Otto Lidenbrock is the tale's central figure, an eccentric German scientist who believes there are volcanic tubes that reach to the very center of the earth. He, his nephew Axel, and their Icelandic guide Hans rappel into Iceland's celebrated inactive volcano Snæfellsjökull, then contend with many dangers, including cave-ins, subpolar tornadoes, an underground ocean, and living prehistoric creatures from the Mesozoic and Cenozoic eras (the 1867 revised edition inserted additional prehistoric material in Chaps. 37–39). Eventually the three explorers are spewed back to the surface by an active volcano, Strombo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tephra
Tephra is fragmental material produced by a volcanic eruption regardless of composition, fragment size, or emplacement mechanism. Volcanologists also refer to airborne fragments as pyroclasts. Once clasts have fallen to the ground, they remain as tephra unless hot enough to fuse into pyroclastic rock or tuff. Tephrochronology is a geochronological technique that uses discrete layers of tephra—volcanic ash from a single eruption—to create a chronological framework in which paleoenvironmental or archaeological records can be placed. When a volcano explodes, it releases a variety of tephra including ash, cinders, and blocks. These layers settle on the land and, over time, sedimentation occurs incorporating these tephra layers into the geologic record. Often, when a volcano explodes, biological organisms are killed and their remains are buried within the tephra layer. These fossils are later dated by scientists to determine the age of the fossil and its place within the geolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
