mt vesuvius

Mt. Vesuvius is on the Campanian Volcanic Arc. This arc is formed over a subduction zone that streches the length of the Italian Peninsula, and was created when the African and Eurasian plates converged.

An especcialy dangerous and unpredictable volcano, Mt. Vesuvius experienced eight eruptions in the last 17,000 years. The most well known of these happened in 79 AD and killed over 16 thousand people. This happened in the city of Pompeii, Italy

Mt. Vesuvius

PompeiiThe eruption of Mt. Vesuvius on the city of Pompeii, in 79 AD, is one of the most well known eruptions in history. It covered the cities of Pompeii and Herculaneum in ash, mud, rocks, and magma. Pompeii is known for the amazing casts it made of people trapped in this catastrophe.

Mt. Vesuvius's last eruption was in 1944, was Europes only eruption in the last 100 years. This eruption destroyed 3 villages and part of a fourth, as well as 88 planes in a US bomber group staioned there during World War II.

The second most violent eruption on Mt. Vesuvius was in April of 1906. This eruption lasted ten days and killed over 2 thousand people

Mt. Vesuvius is now a national park. The Vesuvius National Park was founded on June 5, 1995, in order to preserve animal and vegetable species, vegetable and forest associations, geological peculiarities, palaeontological formations, biological communities, biotopes, scenic and panoramic values, natural processes, and ecological balances. Its purposes are, moreover, the application of ways of management or environmental restoration suitable to realize an integration between man and the natural habitat, also through the protection anthropological, archaeological, historical and architectural values and the protection of traditional and pastoral activities; the promotion of educational and formative activities of scientifis research, that can be interdisciplinary too, the promotion of compatible recreational activities as well; another purpose is the defence and the reconstitution of hydraulic and hydrogeological balances.

Archeologist have found alot of amazing things in Pompeii and restored them. Cast of people were saved, as well as some buildings.

The 79 AD eruption of Vesuvius is why volcanologists use “Plinian” to describe large volcanic eruption clouds. Pliny the Younger, a Roman historian who witnessed the Pompei eruption, wrote the oldest surviving description of the tall, tree-shaped cloud that rose above the volcano. Modern volcanologists use the term to describe large, violent eruptions that produce quickly-expanding clouds of rock, ash and gases which rise many miles into the atmosphere.

Today nearly two million people live in the immediate vicinity of Mount Vesuvius. This volcano has erupted more than 50 times since the eruption in 79 A.D., when it buried Pompeii and its sister city, Herculaneum. After Pompeii was buried, the volcano continued to erupt every 100 years until about 1037 A.D., when it entered a 600-year period of quiet. In 1631, the volcano killed an additional 4000 unsuspecting inhabitants. It was during the restoration after this eruption that workers discovered the ruins of Pompeii, buried and forgotten for nearly 1600 years. It would take another 300 years for the excavations to reveal the story of Pompeii and Herculaneum.

Mount Vesuvius was regarded by the Greeks and Romans as being sacred to the hero and demigod Hercules/Heracles, and the town of Herculaneum, built at its base, was named after him. The mountain is also named after Hercules in a less direct manner: he was the son of the god Zeus and Alcmene of Thebes. Zeus was also known as Ves in his aspect as the god of rains and dews. Hercules was thus alternatively known as Vesouvios, "Son of Ves." This name was corrupted into "Vesuvius." According to other sources, Vesuvius came from the Oscan word fesf which means "smoke." There is a theory that the name "Vesuvius" is derived from the Indo-European root ves- = "hearth".

Located at the northwestern foot of Vesuvius, it was destroyed, together with Pompeii and Stabiae, by the eruption of 79 ce. It was buried under a mass of tufa about 50 to 60 ft (15 to 18 m) deep, which made excavation difficult but preserved many fragile items. Excavation began in the 18th century and uncovered numerous artifacts, including paintings and furniture. Later work uncovered the palaestra (sports ground) and a vast central swimming pool.

Mount Vesuvius is classified as a stratovolcano. Stratovolcano is a term given to volcanoes which have a conical shape, formed due to the deposits of volcanic ash, asphalt, pumice, hardened lava etc. Another interesting fact about Mount Vesuvius is that it is a volcano within a volcano. The height of the outer cone is approximately 4,202 feet (1,281 m) high, while the inner Monte Somma measures 3,770 feet (1,149 m). The cones are separated by a 5 km (3 miles) long valley which is named as Atrio di Cavalio.

If so, many many deaths (including Pliny the Elder), if only considering the bodies that archaeologists have so far found. Also the destruction of at least two cities and probably others that await excavation. The destruction too, of Herculaneum's harbour.Centuries of accumulated energy had been expended in two terrible days. Over 2,000 feet of the vine-clad mountain was gone, pulverised and collapsed. Only a ridge was left. The ashes of the shattered cone had reached Libya, Syria and Egypt and had darkened the sky at Rome.Terrified survivors spread rumours of what had been seen during the cataclysm. They said, "huge men quite surpassing any human stature" had appeared on the mountain, "wandering over the earth day and night and also flitting through the air…and, moreover, a sound of trumpets was heard."Vesuvius was a ruin, but it refused to subside back into sleep. According to the Roman historian Cassius Dio, before the eruption, the mountain "was equally high at all points". Now it resembled an amphitheatre, and the collapsed centre sent up smoke by day and fire by night. "In fact, it gives the impression that quantities of incense of all kinds are being burned in it. This, now, goes on all the time…"The impact of the eruption was such that the Sarno river changed its course and the sea beach was raised. Many physical features of this area were altered, with the vegetation at the foot of the mountain being denuded.

Prior to the eruption, there were earthquakes, including a substantial one in A.D. 62 that Pompeii was still recovering from in 79. There was another earthquake in 64, while Nero was performing in Naples. Earthquakes were seen as facts of life. However, in 79, springs and wells dried up, and in August, the earth cracked, the sea became turbulent, and the animals showed signs that something was coming. When the eruption of the 24th of August began, it looked like a pine tree in the sky, according to Pliny, spewing noxious fumes, ash, smoke, mud, stones, and flames.

The pompeii worm is considered Earth's hottest animal, because it has the highest heat resistance of any animal ever recorded. Discovered in the early 1980s by French scientists, the Pompeii worm is about 4 inches long with tentacle-like, scarlet gills on its head. A gray "fleece" of bacteria covers the worm's back. It is called the Pompeii worm because it makes paper-like tubes, and attatches them to hydrothermal vents. This way the hot water goes not only up, but around the vents, hitting the worms' homes and producing the temperatures that they like. Learn more about it by clicking on the picture above

Vesuvius has a long historic and literary tradition. It was considered a divinity of the genius type at the time of the eruption of 79 AD: it appears under the inscribed name Vesuvius as a serpent in the decorative frescos of many lararia, or household shrines, surviving from Pompeii. An inscription from Capua[2] to IOVI VESVVIO indicates that he was worshipped as a power of Jupiter; that is, Jupiter Vesuvius.[3]

Vesuvius is a distinctive humpbacked" mountain, consisting of a large cone (Gran Cono) partially encircled by the steep rim of a summit caldera caused by the collapse of an earlier and originally much higher structure called Monte Somma.[10] The Gran Cono was produced during the eruption of AD 79. For this reason, the volcano is also called Somma-Vesuvius or Somma-Vesuvio.

Many very popular books have been written about Pompeii and the eruption of Mt. Vesuvius

The eruption of Mt. Vesuvius in 79 AD is one of the most well known eruptions in the world.

When Spartacus led the slave rebellion of 73 B.C., he found the crater on top of Vesuvius to be a huge basin a mile across and filled with a dense growth of vines. It served as a secure camp for the rebels until three thousand Roman soldiers laid siege. The modern crater of Mount Vesuvius, shown above, is a huge empty bowl. There is no molten lava to be seen today. Of course, this peaceful appearance could change tomorrow.
