Vulcano
Vulcano ( scn, Vurcanu) or Vulcan is a small volcanic island belonging to Italy in the Tyrrhenian Sea, about north of Sicily and located at the southernmost end of the seven Aeolian Islands. The island is known for its volcanic activity and contains several volcanic calderas, including one of the four active volcanoes in Italy that are not submarine. The English word "volcano", and its equivalent in several European languages, derives from the name of this island, which derives from the Roman belief that the tiny island was the chimney of Vulcan, the Roman god of fire. In November 2021, 150 people were evacuated from the island's harbour area due to increased volcanic activity and gases; an amber alert had been issued in October 2021 after several significant changes in the volcano's parameters. Geography Vulcano is located approximately north of Sicily and is approximately long by wide. The island is in area and rises to above sea level. The island is separated by a ...

Vulcan (mythology)
Vulcan ( la, Vulcanus, in archaically retained spelling also ''Volcanus'', both pronounced ) is the god of fire including the fire of volcanoes, deserts, metalworking and the forge in ancient Roman religion and myth. He is often depicted with a blacksmith's hammer. The Vulcanalia was the annual festival held August 23 in his honor. His Greek counterpart is Hephaestus, the god of fire and smithery. In Etruscan religion, he is identified with Sethlans. Vulcan belongs to the most ancient stage of Roman religion: Varro, the ancient Roman scholar and writer, citing the Annales Maximi, records that king Titus Tatius dedicated altars to a series of deities including Vulcan. Etymology The origin of the name is unclear. Roman tradition maintained that it was related to Latin words connected to lightning (), which in turn was thought of as related to flames. This interpretation is supported by Walter William Skeat in his etymological dictionary as meaning ''lustre''. It has be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vulcanian Eruption
A Vulcanian eruption is a type of volcanic eruption characterized by a dense cloud of ash-laden gas exploding from the crater and rising high above the peak. They usually commence with phreatomagmatic eruptions which can be extremely noisy due to the rising magma heating water in the ground. This is usually followed by the explosive clearing of the vent and the eruption column is dirty grey to black as old weathered rocks are blasted out of the vent. As the vent clears, further ash clouds become grey-white and creamy in colour, with convolutions of the ash similar to those of Plinian eruptions. The term ''Vulcanian'' was first used by Giuseppe Mercalli, witnessing the 1888–1890 eruptions on the island of Vulcano. His description of the eruption style is now used all over the world. Mercalli described Vulcanian eruptions as "...Explosions like cannon fire at irregular intervals..." Their explosive nature is due to increased silica content of the magma. Almost all types of magma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Giuseppe Mercalli
Giuseppe Mercalli (21 May 1850 – 19 March 1914) was an Italian volcanologist and Catholic Church, Catholic priest. He is known best for the Mercalli intensity scale for measuring earthquake intensity. Biography Born in Milan, Mercalli was ordained a Roman Catholic priest and soon became a professor of Natural Sciences at the seminary of Milan. The Italy, Italian government appointed him a professor at Domodossola, followed by a job at Reggio di Calabria. He was professor of geology at the University of Catania during the late 1880s and finally was given a job at Naples University. He was also director of the Vesuvius Observatory until the time of his death. Giuseppe Mercalli also observed eruptions of the volcanoes Stromboli and Vulcano in the Aeolian Islands. His descriptions of these eruptions became the basis for two indices of the Volcanic Explosivity Index: 1 – Strombolian eruption, and 2 – Vulcanian eruption. He also photographed Vesuvius immediately after its er ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Prediction Of Volcanic Activity
Prediction of volcanic activity, or volcanic eruption forecasting, is an interdisciplinary monitoring and research effort to predict the time and severity of a volcano's eruption. Of particular importance is the prediction of hazardous eruptions that could lead to catastrophic loss of life, property, and disruption of human activities. Seismic waves (seismicity) General principles of volcano seismology * Seismic activity (earthquakes and tremors) always occurs as volcanoes awaken and prepare to erupt and are a very important link to eruptions. Some volcanoes normally have continuing low-level seismic activity, but an increase may signal a greater likelihood of an eruption. The types of earthquakes that occur and where they start and end are also key signs. Volcanic seismicity has three major forms: short-period earthquake, long-period earthquake, and harmonic tremor. * Short-period earthquakes are like normal fault-generated earthquakes. They are caused by the fracturing of bri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lipari
Lipari (; scn, Lìpari) is the largest of the Aeolian Islands in the Tyrrhenian Sea off the northern coast of Sicily, southern Italy; it is also the name of the island's main town and ''comune'', which is administratively part of the Metropolitan City of Messina. Its population is 12,821, but during the May to September tourist season, the total population may reach up to 20,000. Geography Lipari is the largest of a chain of islands in a volcanic archipelago situated in between Vesuvius and Etna. The island has a surface area of 37.6 km2 and is 30 km from Sicily. Besides the main town, most of the year-round population resides in one of the four main villages: Pianoconte is almost due west across the island, Quattropani in the northwest, Acquacalda along the northern coast, whereas Canneto is on the eastern shore north of Lipari town. The highest point on the island is Monte Chirica at 602 m (1975 ft). Geology Geologists agree on the fact that Lipari was created by a suc ...

Eurasian Plate
The Eurasian Plate is a tectonic plate that includes most of the continent of Eurasia (a landmass consisting of the traditional continents of Europe and Asia), with the notable exceptions of the Indian subcontinent, the Arabian subcontinent and the area east of the Chersky Range in eastern Siberia. It also includes oceanic crust extending westward to the Mid-Atlantic Ridge and northward to the Gakkel Ridge. The eastern edge is a boundary with the North American Plate to the north and a boundary with the Philippine Sea Plate to the south and possibly with the Okhotsk Plate and the Amurian Plate. The southern edge is a boundary with the African Plate to the west, the Arabian Plate in the middle and the Indo-Australian Plate to the east. The western edge is a divergent boundary with the North American Plate forming the northernmost part of the Mid-Atlantic Ridge, which is straddled by Iceland. All volcanic eruptions in Iceland, such as the 1973 eruption of Eldfell, the 1783 eruptio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

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 ...
