The mountain
Mount Vesuvius (1,281 meters- 4,203 ft at present) is one of those legendary and mythic mountains the Earth paid regularly tribute. Monte Vesuvio in Italian modern langage or Mons Vesuvius in antique Latin langage is a stratovolcano in the Gulf of Naples (Italy) about 9 km (5.6 mi) east of Naples and a short distance from the shore.
It is one of several volcanoes which form the Campanian volcanic arc. Vesuvius consists of a large cone partially encircled by the steep rim of a summit caldera caused by the collapse of an earlier and originally much higher structure.
Mount Vesuvius is best known for its eruption in AD 79 that led to the burying and destruction of the Roman antique cities of Pompeii, Herculaneum, and several other settlements. That eruption ejected a cloud of stones, ash, and fumes to a height of 33 km (20.5 mi), spewing molten rock and pulverized pumice at the rate of 1.5 million tons per second, ultimately releasing a hundred thousand times the thermal energy released by the Hiroshima bombing. At least 1,000 people died in the eruption. The only surviving eyewitness account of the event consists of two letters by Pliny the Younger to the historian Tacitus.
Vesuvius has erupted many times since and is the only volcano on the European mainland to have erupted within the last hundred years. Nowadays, it is regarded as one of the most dangerous volcanoes in the world because of the population of 3,000,000 people living nearby and its tendency towards explosive eruptions (said Plinian eruptions). It is the most densely populated volcanic region in the world.
Vesuvius was formed as a result of the collision of two tectonic plates, the African and the Eurasian. The former was subducted beneath the latter, deeper into the earth. As the water-saturated sediments of the oceanic African plate were pushed to hotter depths in the earth, the water boiled off and caused the melting point of the upper mantle to drop enough to create partial melting of the rocks. Because magma is less dense than the solid rock around it, it was pushed upward. Finding a weak place at the Earth's surface it broke through, producing the volcano.
he area around Vesuvius was officially declared a national park on June 5, 1995. The summit of Vesuvius is open to visitors and there is a small network of paths around the mountain that are maintained by the park authorities on weekends.
There is access by road to within 200 metres (660 ft) of the summit (measured vertically), but thereafter access is on foot only. There is a spiral walkway around the mountain from the road to the crater.
The first funicular cable car on Mount Vesuvius opened in 1880. It was later destroyed by the 1944 eruption. "Funiculì, Funiculà", a famous Neapolitan song with lyrics by journalist Peppino Turco set to music by composer Luigi Denza, commemorates its opening.
George Julius Poulett Scrope (1797- 1876) was an English geologist and political economist as well as a magistrate for Stroud in Gloucestershire. He was educated at Harrow, and for a short time at Pembroke College, Oxford, but in 1816 he entered St John's College, Cambridge, graduating BA in 1821. Through the influence of Edward Clarke and Adam Sedgwick he became interested in mineralogy and geology.
During the winter of 1816–1817 he was at Naples, and was so keenly interested in Vesuvius that he renewed his studies of the volcano in 1818; and in the following year visited Etna and the Lipari Islands. In 1821 he married the daughter and heiress of William Scrope of Castle Combe, Wiltshire, and assumed her name; and he entered the House of Commons of the United Kingdom in 1833 as MP for Stroud, retaining his seat until 1868.
Meanwhile he began to study the volcanic regions of central France in 1821, and visited the Eifel district in 1823. In 1825 he published Considerations on Volcanos, leading to the establishment of a new theory of the Earth, and in the following year was elected FRS. This earlier work was subsequently amplified and issued under the title of Volcanos (1862); an authoritative text-book of which a second edition was published ten years later.
In 1827 he issued his classic Memoir on the Geology of Central France, including the Volcanic formations of Auvergne, the Velay and the Vivarais, a quarto volume illustrated by maps and plates. The substance of this was reproduced in a revised and somewhat more popular form in The Geology and extinct Volcanos of Central France (1858). These books were the first widely published descriptions of the Chaîne des Puys, a chain of over 70 small volcanoes in the Massif Central.
Scrope was awarded the Wollaston Medal by the Geological Society of London in 1867. Among his other works was the History of the Manor and Ancient Barony of Castle Combe (printed for private circulation, 1852).
He died at Fairlawn near Cobham, Surrey on 19 January 1876.
