Lava
Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or underwater, usually at temperatures from . The volcanic rock resulting from subsequent cooling is also often called lava. A lava flow is an outpouring of lava during an effusive eruption. (An explosive eruption, by contrast, produces a mixture of volcanic ash and other fragments called tephra, not lava flows.
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.
Catania
Catania (kəˈtɑːniə, alsoUK-ˈteɪn-, US-ˈtæn-, Sicilian and kaˈtaːnja) is the second largest municipality in Sicily, after Palermo, both by area and by population. Despite its reputation as the second city of the island, Catania is the largest Sicilian conurbation, among the largest in Italy, as evidenced also by the presence of important road and rail transport infrastructures as well as by the main airport in Sicily, fifth in Italy. It is located on Sicily's east coast, at the base of the active volcano, Mount Etna, and it faces the Ionian Sea.
Teide
Teide, or Mount Teide, ( El Teide, Pico del Teide, ˈpiko ðel ˈtejðe, "Peak of Teide") is a volcano on Tenerife in the Canary Islands, Spain. Its summit (at ) is the highest point in Spain and the highest point above sea level in the islands of the Atlantic. If measured from the ocean floor, its height of makes Teide the third-highest volcano in the world, and is described by UNESCO and NASA as Earth's third-tallest volcanic structure. Teide's elevation above sea level makes Tenerife the tenth highest island in the world.
Allied invasion of Sicily
The Allied invasion of Sicily, also known as the Battle of Sicily and Operation Husky, was a major campaign of World War II in which the Allied forces invaded the island of Sicily in July 1943 and took it from the Axis powers (Fascist Italy and Nazi Germany). It began with a large amphibious and airborne operation, followed by a six-week land campaign, and initiated the Italian campaign. To divert some of the Axis forces to other areas, the Allies engaged in several deception operations, the most famous and successful of which was Operation Mincemeat.
Plinian eruption
Plinian eruptions or Vesuvian eruptions are volcanic eruptions marked by their similarity to the eruption of Mount Vesuvius in 79 AD, which destroyed the ancient Roman cities of Herculaneum and Pompeii. The eruption was described in a letter written by Pliny the Younger, after the death of his uncle Pliny the Elder. Plinian/Vesuvian eruptions are marked by columns of volcanic debris and hot gases ejected high into the stratosphere, the second layer of Earth's atmosphere.
Vulcan (mythology)
Vulcan (Vulcanus, in archaically retained spelling also Volcanus, both pronounced wʊɫˈkaːnʊs) 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.
Shield volcano
A shield volcano is a type of volcano named for its low profile, resembling a warrior's shield lying on the ground. It is formed by the eruption of highly fluid (low viscosity) lava, which travels farther and forms thinner flows than the more viscous lava erupted from a stratovolcano. Repeated eruptions result in the steady accumulation of broad sheets of lava, building up the shield volcano's distinctive form. Shield volcanoes are found wherever fluid, low-silica lava reaches the surface of a rocky planet.
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.
Sicilian language
Sicilian (sicilianu, sɪ(t)ʃɪˈljaːnʊ; siciliano) is a Romance language that is spoken on the island of Sicily and its satellite islands. It belongs to the broader Extreme Southern Italian language group (in Italian italiano meridionale estremo). Ethnologue (see below for more detail) describes Sicilian as being "distinct enough from Standard Italian to be considered a separate language", and it is recognized as a minority language by UNESCO. It has been referred to as a language by the Sicilian Region.
