Volcanism In 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 Pleistoc ...

Mount Etna
Mount Etna, or simply Etna ( it, Etna or ; scn, Muncibbeḍḍu or ; la, Aetna; grc, Αἴτνα and ), is an active stratovolcano on the east coast of Sicily, Italy, in the Metropolitan City of Catania, between the cities of Messina and Catania. It lies above the convergent plate margin between the African Plate and the Eurasian Plate. It is one of the tallest active volcanoes in Europe, and the tallest peak in Italy south of the Alps with a current height (July 2021) of , though this varies with summit eruptions. Over a six-month period in 2021, Etna erupted so much volcanic material that its height increased by approximately , and the southeastern crater is now the tallest part of the volcano. Etna covers an area of with a basal circumference of . This makes it by far the largest of the three active volcanoes in Italy, being about two and a half times the height of the next largest, Mount Vesuvius. Only Mount Teide on Tenerife in the Canary Islands surpasses i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mainland Europe
Continental Europe or mainland Europe is the contiguous continent of Europe, excluding its surrounding islands. It can also be referred to ambiguously as the European continent, – which can conversely mean the whole of Europe – and, by some, simply as the Continent. When Eurasia is regarded as a single continent, Europe is treated as a subcontinent, and called as European subcontinent. The old notion of Europe as a cultural term was centred on core Europe (''Kerneuropa''), the continental territory of the historical Carolingian Empire, corresponding to modern France, Italy, German-speaking Europe and the Benelux states (historical Austrasia). This historical core of "Carolingian Europe" was consciously invoked in the 1950s as the historical ethno-cultural basis for the prospective European integration (see also Multi-speed Europe). Usage The most common definition of Mainland Europe excludes these continental islands: the Greek Islands, Cyprus, Malta, Sicily, S ...

International Association Of Volcanology And Chemistry Of The Earth's Interior
The International Association of Volcanology and Chemistry of the Earth's Interior (IAVCEI) is a learned society that focuses on research in volcanology, efforts to mitigate volcanic disasters, and research into closely related disciplines, such as igneous geochemistry and petrology, geochronology, volcanogenic mineral deposits, and the physics of the generation and ascent of magmas in the upper mantle and crust. It is one of eight constituent associations of the International Union of Geodesy and Geophysics (IUGG). IAVCEI is run by an executive committee whose membership changes every four years. The Executive determines policies for the Association, enacting them through a series of commissions and task groups. ''Bulletin of Volcanology'' is the journal of IAVCEI.IAVCEI About Us.

Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing a faunal interchange between the two reg ...

Geology
Geology () is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology, and so is treated as one major aspect of integrated Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates. Geologists broadly study the properties and processes of E ...

Sardinia
Sardinia ( ; it, Sardegna, label=Italian, Corsican and Tabarchino ; sc, Sardigna , sdc, Sardhigna; french: Sardaigne; sdn, Saldigna; ca, Sardenya, label=Algherese and Catalan) is the second-largest island in the Mediterranean Sea, after Sicily, and one of the 20 regions of Italy. It is located west of the Italian Peninsula, north of Tunisia and immediately south of the French island of Corsica. It is one of the five Italian regions with some degree of domestic autonomy being granted by a special statute. Its official name, Autonomous Region of Sardinia, is bilingual in Italian and Sardinian: / . It is divided into four provinces and a metropolitan city. The capital of the region of Sardinia — and its largest city — is Cagliari. Sardinia's indigenous language and Algherese Catalan are referred to by both the regional and national law as two of Italy's twelve officially recognized linguistic minorities, albeit gravely endangered, while the regional law provides ...

Strait Of Sicily
The Strait of Sicily (also known as Sicilian Strait, Sicilian Channel, Channel of Sicily, Sicilian Narrows and Pantelleria Channel; it, Canale di Sicilia or the Stretto di Sicilia; scn, Canali di Sicilia or Strittu di Sicilia, ar, مضيق صقلية ' or ') is the strait between Sicily and Tunisia. The strait is about wide and divides the Tyrrhenian Sea and the western Mediterranean Sea, from the eastern Mediterranean Sea. The maximum depth is . Deep currents in the strait flow from east to west, and the current nearer the surface travels from west to east. This unusual water flow is of interest to oceanographers. There are regular ferries between Sicily and Tunis across the Strait of Sicily. The island of Pantelleria lies in the middle of the strait. The Strait of Sicily is located between, at the eastern side, Tunisia and the Malta Bank and on the northern side, Sicily, Italy. Within the Central Mediterranean sea it is one of the topographically complex region ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mediterranean Sea
The Mediterranean Sea is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean Basin and almost completely enclosed by land: on the north by Western and Southern Europe and Anatolia, on the south by North Africa, and on the east by the Levant. The Sea has played a central role in the history of Western civilization. Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago. The Mediterranean Sea covers an area of about , representing 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa—is only wide.

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 P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Campanian Volcanic Arc
The Campanian volcanic arc is a volcanic arc that consists of a number of active, dormant, and extinct volcanoes in the Campania region of Italy. The Campanian volcanic arc centers on the bay of Naples and includes: * Mount Vesuvius: an active volcano that last erupted in 1944. * Phlegraean Fields: a huge, ancient caldera containing the western area of Naples. The area is a collection of numerous extinct craters that are evidence of ancient eruptions; however, also included in this area is Solfatara, a shallow volcanic crater still emitting jets of sulfur fumes and, thus, still active. * Ischia: an island 20 kilometres west of Naples, it last erupted in 1302. * Palinuro, Vavilev, Marsili, and Magnaghi: undersea extinct or dormant volcanoes south of Vesuvius. The last three were discovered in the 1950s and bear the names of the geologists who discovered them. Palinuro was known earlier. , there was some concern about the state of "dormancy" of Marsili, which is 3,000 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subduction
Subduction is a geological process in which the oceanic lithosphere is recycled into the Earth's mantle at convergent boundaries. Where the oceanic lithosphere of a tectonic plate converges with the less dense lithosphere of a second plate, the heavier plate dives beneath the second plate and sinks into the mantle. A region where this process occurs is known as a subduction zone, and its surface expression is known as an arc-trench complex. The process of subduction has created most of the Earth's continental crust. Rates of subduction are typically measured in centimeters per year, with the average rate of convergence being approximately two to eight centimeters per year along most plate boundaries. Subduction is possible because the cold oceanic lithosphere is slightly denser than the underlying asthenosphere, the hot, ductile layer in the upper mantle underlying the cold, rigid lithosphere. Once initiated, stable subduction is driven mostly by the negative buoyancy of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
