Ferdinandea
Ferdinandea Island (also Graham Island, Graham Bank or Graham Shoal; french: Ile Julia) is a certain volcanic island/seamount in the Mediterranean Sea near the island of Sicily that has, on more than one occasion, risen above the Mediterranean via volcanic action and soon thereafter been washed away. Since 300 BC this cycle of events has occurred four times. The top of the island is presently 6 metres below sea level. The island's most recent "appearance" occurred in July 1831, but then by January 1832 the portion of the island above sea level had been entirely washed away again by the wind and the waves of the Mediterranean Sea. The 1831 version of the island was first visited by the Sicilian customs official Michele Fiorini on 17 July 1831, who planted an oar there to claim the newly emerged island for the Kingdom of Sicily. Historical description of brief appearance of island. On 2 August 1831 Humphrey Fleming Senhouse, the captain of the first rate Royal Navy ship of ...

Empedocles (volcano)
Empedocles is a large underwater volcano located 40 km off the southern coast of Sicily named after the Greek philosopher Empedocles who believed that everything on Earth was made up of the four elements. According to Italy's National Institute of Geophysics and Volcanology, the volcanic structure is around 400 meters high, with a base 30 km long and 25 km wide. Located in the Campi Flegrei del Mar di Sicilia (Phlegraean Fields of the Strait of Sicily), Empedocles is composed of what was once believed to be separate volcanic centers, including Graham Island (Ferdinandea).Volcano larger than Washington D.C. discovered [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Constant Prévost
Louis-Constant Prévost (4 June 1787 – 14 August 1856) was a French geologist. Early life and education Prévost was born in Paris to Louis Prévost, a tax farmer, receiver of the ''rentes'' of Paris. He was educated there at the Central Schools, where, inspired by the lectures of Georges Cuvier, his particular mentor Alexandre Brongniart, and André Marie Constant Duméril, he determined to devote himself to natural science. He took his degree in Letters and Sciences in 1811, and for a time pursued the study of medicine and anatomy. Career Mainly through the influence of Brongniart he turned his attention to geology. During the years 1816 to 1819 he took advantage of the necessity of accompanying his associate Philippe de Girard, who was seeking out a site for establishing a textile mill near Vienna, by making a special study of the Viennese Basin. In doing so, he pointed out for the first time the presence of Tertiary strata like those of the Paris Basin, but which inc ...

Campi Flegrei Del Mar Di Sicilia
Campi Flegrei del Mar di Sicilia is a field of submarine volcanoes located south-west of Sicily. It includes the vent of Ferdinandea, otherwise known as Graham Island, which erupted and emerged above sea level in 1831, and encompasses a larger volcano known as Empedocles. The last recorded eruption was in 1867, from a vent named Pinne. There was mild seismic unrest at Ferdinandea Ferdinandea Island (also Graham Island, Graham Bank or Graham Shoal; french: Ile Julia) is a certain volcanic island/seamount in the Mediterranean Sea near the island of Sicily that has, on more than one occasion, risen above the Mediterranean v ... in 2000 - 2002.

Eruption
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 erupti ...

Map Of Graham Island
A map is a symbolic depiction emphasizing relationships between elements of some space, such as objects, regions, or themes. Many maps are static, fixed to paper or some other durable medium, while others are dynamic or interactive. Although most commonly used to depict geography, maps may represent any space, real or fictional, without regard to context or scale, such as in brain mapping, DNA mapping, or computer network topology mapping. The space being mapped may be two dimensional, such as the surface of the earth, three dimensional, such as the interior of the earth, or even more abstract spaces of any dimension, such as arise in modeling phenomena having many independent variables. Although the earliest maps known are of the heavens, geographic maps of territory have a very long tradition and exist from ancient times. The word "map" comes from the , wherein ''mappa'' meant 'napkin' or 'cloth' and ''mundi'' 'the world'. Thus, "map" became a shortened term referring to ...

First Punic War
The First Punic War (264–241 BC) was the first of Punic Wars, three wars fought between Roman Republic, Rome and Ancient Carthage, Carthage, the two main powers of the western Mediterranean in the early 3rd century BC. For 23 years, in the longest continuous conflict and greatest naval war of Ancient history, antiquity, the two powers struggled for supremacy. The war was fought primarily on the Mediterranean island of Sicily and its surrounding waters, and also in North Africa. After immense losses on both sides, the Carthaginians were defeated. The war began in 264 BC with the Romans gaining a foothold on Sicily at Battle of Messana, Messana (modern Messina). The Romans then pressed Syracuse, Sicily, Syracuse, the only significant independent power on the island, into allying with them and laid siege to Carthage's main base at Agrigento, Akragas. A large Carthaginian army attempted to lift the siege in 262 BC but was heavily defeated at the Battle of Agri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Volcanic
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plate ...

Pantelleria
Pantelleria (; Sicilian: ''Pantiddirìa'', Maltese: ''Pantellerija'' or ''Qawsra''), the ancient Cossyra or Cossura, is an Italian island and comune in the Strait of Sicily in the Mediterranean Sea, southwest of Sicily and east of the Tunisian coast. On clear days Tunisia is visible from the island. Administratively Pantelleria's comune belongs to the Sicilian province of Trapani. The population of Pantelleria 2022 was 7,335 in 2022, according to istat.it. Description With an area of , Pantelleria is the largest volcanic satellite island of Sicily. The last eruption occurred below sea level in 1891, and today phenomena related to volcanic activity are present, such as hot springs and fumaroles. The highest peak, the ''Montagna Grande'', reaches above sea level. The islanders speak Pantesco, a dialect of Sicilian influenced by Arabic. Names The Carthaginians knew the island as ( xpu, 𐤉𐤓𐤍𐤌) or (). The Greek geographers recorded it as ''Kossyra'' ( grc, Κ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seamount
A seamount is a large geologic landform that rises from the ocean floor that does not reach to the water's surface (sea level), and thus is not an island, islet or cliff-rock. Seamounts are typically formed from extinct volcanoes that rise abruptly and are usually found rising from the seafloor to in height. They are defined by oceanographers as independent features that rise to at least above the seafloor, characteristically of conical form.IHO, 2008. Standardization of Undersea Feature Names: Guidelines Proposal form Terminology, 4th ed. International Hydrographic Organization and Intergovernmental Oceanographic Commission, Monaco. The peaks are often found hundreds to thousands of meters below the surface, and are therefore considered to be within the deep sea. During their evolution over geologic time, the largest seamounts may reach the sea surface where wave action erodes the summit to form a flat surface. After they have subsided and sunk below the sea surface such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
