As well as producing Mt Etna, Vesuvius was also formed, but it is part of a different volcanic arc. Brilliantly preserved until now. As the water-saturated sediments [74], The volcano is closely monitored by the Osservatorio Vesuvio in Naples with extensive networks of seismic and gravimetric stations, a combination of a GPS-based geodetic array and satellite-based synthetic aperture radar to measure ground movement and by local surveys and chemical analyses of gases emitted from fumaroles. [7][40], The AD 79 eruption was preceded by a powerful earthquake in 62, which caused widespread destruction around the Bay of Naples, and particularly to Pompeii. Pompeii was destroyed by the violent eruption of Mount Vesuvius on August 24, 79 CE. [50] This period would have been the last opportunity to escape. Its collateral forms were Vesaevus, Vesevus, Vesbius and Vesvius. Mount Vesuvius is a volcano that is famous for its erupt ion in 79 A.D. when it buried Pompeii in more than 10 feet of pumice and ash. Please refer to the appropriate style manual or other sources if you have any questions. Another study used the magnetic characteristics of over 200 samples of roof-tile and plaster fragments collected around Pompeii to estimate equilibrium temperature of the pyroclastic flow. [15] Writers in ancient Greek used Οὐεσούιον or Οὐεσούιος. All of this is intended to track magma rising underneath the volcano. How to use a map. Thirty-eight percent of the 1,044 were found in the ash fall deposits, the majority inside buildings. Scientists believe that Mount Vesuvius formed almost 200,000 years ago. …but some now believe that date is wrong The slopes of the volcano are scarred by lava flows, while the rest are heavily vegetated, with scrub and forests at higher altitudes and vineyards lower down. The former was subducted beneath the latter, deeper into the earth. [citation needed], The caldera started forming during an eruption around 17,000-18,000 years ago,[20][21][22] and was enlarged by later paroxysmal eruptions,[23] ending in the one of AD 79. Mount Vesuvius. The big eruption blew lava, poison gas, ashes and rocks up to twenty miles into the atmosphere. After 1872 slow lava effusions, lasting several years formed small lava accumulation (lava domes) in the proximity of the crater. [8], Vesuvius has erupted many times since, and is the only volcano on the European mainland to have erupted within the last hundred years. An epigram by the poet Martial in 88 AD suggests that both Venus, patroness of Pompeii, and Hercules were worshipped in the region devastated by the eruption of 79.[14]. It is famous for an eruption that happened in ad 79. • More than 25% of Sicily's population lives on Etna's slopes. He escaped by twisting ropes of vine branches and descending through unguarded fissures in the rim. It was at the southeastern base of Mount Vesuvius and was built on a spur formed by a prehistoric lava flow to the north of the mouth of the Sarnus (modern Sarno) River. The former was subducted beneath the latter, deeper into the earth. Small earthquakes started taking place four days before the eruption[44] becoming more frequent over the next four days, but the warnings were not recognized.[a]. Vesuvius as seen from above Sorrento. Vesuvius has a long history of eruptions, beginning with the first known eruption in 5960 B.C. The depositional temperature of these pyroclastic surges ranged up to 300 °C (572 °F). Within an hour this cloud reached nearly fourteen kilometres high. Vesuvius is still regarded as an active volcano, although its current activity produces little more than sulfur-rich steam from vents at the bottom and walls of the crater. In 1872, after the eruption, Vesuvius cone had its maximum elevation at 1335 m a.s.l.. It spewed smoke and toxic gas 20 miles into the air, which soon spread to the town. [46] The initial major explosion produced a column of ash and pumice ranging between 15 and 30 kilometres (49,000 and 98,000 ft) high, which rained on Pompeii to the southeast but not on Herculaneum upwind. The Somma Rim, a caldera-like structure formed by the collapse of a stratovolcano about 17,000 year ago, flanks Vesuvius to the east. Where lava, volcanic ash, and poisonous gas’s escape from. Around 11,000 years ago: the Lagno Amendolare eruption, smaller than the Mercato eruption. Rock and lava pile up, layer on top of layer. The famous Mount Vesuvius, which is known throughout the world for its massively destructive eruption in A.D. 79, is located near Naples in Italy. Between 1660 and 1944 several of these cycles were observed. 5. At the summit of the cone is a large crater about 1,000 feet (about 305 metres) deep and 2,000 feet (about 610 metres) across; it was formed in the eruption of 1944. It is likely that most, or all, of the known victims in this town were killed by the surges. These events have partly destroyed Mount Somma, the most ancient volcano, inside which the Gran Cono of Vesuvius formed: this is the volcanic complex Somma - Vesuvius. A reservoir as wide as 3 kilometers of smoldering magma had formed beneath the volcano, held by a plug of old magma. Advised by the helmsman to turn back, he stated "Fortune favors the brave" and ordered him to continue on to Stabiae (about 4.5 kilometers from Pompeii). This cloud and a request by a messenger for an evacuation by sea prompted the elder Pliny to order rescue operations in which he sailed away to participate. [59] His body was found with no apparent injuries on the next day, after dispersal of the plume. There are industrial towns along the coast of the Bay of Naples and small agricultural centres on the northern slopes. His nephew attempted to resume a normal life, but that night a tremor awoke him and his mother, prompting them to abandon the house for the courtyard. The cloud obscured Point Misenum near at hand and the island of Capraia (Capri) across the bay. But in the summer of A.D. 79, the nearby Mount Vesuvius volcano erupted. Reconstructions of the eruption and its effects vary considerably in the details but have the same overall features. [70] The specific areas actually affected by the ash cloud depend upon the particular circumstances surrounding the eruption. These are thought to have been killed mainly by roof collapses, with the smaller number of victims found outside of buildings probably being killed by falling roof slates or by larger rocks thrown out by the volcano. Mount Vesuvius is a complex stratovolcano, built by layers of … Others include Campi Flegrei, a large caldera a few kilometers to the north west, Mount Epomeo, 20 kilometres (12 mi) to the west on the island of Ischia, and several undersea volcanoes to the south. By late afternoon of the second day, the eruption was over, leaving only haze in the atmosphere through which the sun shone weakly. Eight major explosive eruptions have occurred since, including the 79 CE eruption that destroyed Pompeii and other towns. Vesuvius is a stratovolcano. A.D. 79: One of the most famous volcanoes is Mount Vesuvius, which sits along the Bay of Naples in southern Italy. As the water-saturated sediments, of the oceanic African plate were pushed to hotter depths inside the planet, the water boiled off and lowered the melting point of the upper mantle enough to partially melt the rocks. [51] Any population remaining in structural refuges could not have escaped, as the city was surrounded by gases of incinerating temperatures. As only 85 metres (279 ft) of the coast have been excavated, further casualties may be discovered. Mount Vesuvius will erupt again at some point, but scientists have ways of predicting when this might happen. First Letter; At that time [24 August AD 79] my uncle was at Misenum in command of the fleet. The active cone of Vesuvius was constructed within a large caldera of the ancestral Monte Somma volcano, thought to have formed incrementally beginning about 17 000 years ago. The latest scientific studies of the ash produced by Vesuvius reveals a multi-phase eruption. While the ‘main peak’ is named Vesuvius, there is another mountain which is attached to it, Monte Somma. During the quiescent stage the volcano’s mouth would be obstructed, whereas in the eruptive stage it would be almost continuously open. Omissions? Vesuvius was then built up by a series of lava flows, with some smaller explosive eruptions interspersed between them. Other peoples of unknown provenance are said to have been there at some time by various ancient authors. The rest were concentrated in arched chambers at a density of as high as 3 persons per square metre. Grab a copy of our NEW encyclopedia for Kids! The cone of Mount Vesuvius looms large over the city of Naples in southern Italy. 16,000 years ago: the Green Pumice (Pomici Verdoline) eruption, VEI 5. Even the inside of the crater was moderately filled with shrubbery. [47] Surges are identified in the deposits by dune and cross-bedding formations, which are not produced by fallout. The tephra and hot ash from multiple days of the eruption damaged the fabric control surfaces, the engines, the Plexiglas windscreens and the gun turrets of the 340th's B-25 Mitchell medium bombers. Magma sitting in an underground chamber for many years will start to see higher melting point constituents such as olivine crystallizing out. [26], Vesuvius was formed as a result of the collision of two tectonic plates, the African and the Eurasian. Vesuvius erupted catastrophically in 79 A.D., burying the towns of Herculaneum and Pompeii. Vesuvius is part of the Campanian volcanic arc, a line of volcanoes that formed over a subduction zone created by the convergence of the African and Eurasian plates. National Trust - Why is Mount Vesuvius so famous? When Vesuvius had burst out the cloud that Pliny had seen, it was due to a chemical reaction involving water and gases that had bust the lava plug trapping the magma-Vesuvius had come back to life. The volcano also has a semicircular ridge called Mount Somma that rises to 3,714 feet (1,132 m). Cores were dated by potassium–argon and argon–argon dating. [43] Some of the damage had still not been repaired when the volcano erupted. Around 26 civilians were killed in the disaster, displacing around 12,000 people in the process. In the first letter to Tacitus, Pliny the Younger suggested that his uncle's death was due to the reaction of his weak lungs to a cloud of poisonous, sulphurous gas that wafted over the group. Articles from Britannica Encyclopedias for elementary and high school students. Higher up, the mountain is covered with copses of oak and chestnut, and on the northern side along the slopes of Mount Somma the woods proceed to the very summit. It was long-believed Vesuvius erupted at around 1pm on 24 August 79 AD… Dirt and rock was thrown up into the air and a huge ash cloud formed above the volcano. Surges 3 and 4 are believed by the authors to have buried Pompeii. Active Volcanos are defined by being the most recent eruptions, usually ranging in eruptions less than 10, 000 years ago. The morning of the first day was perceived as normal by the only eyewitness to leave a surviving document, Pliny the Younger. As the ship was preparing to leave the area, a messenger came from his friend Rectina (wife of Tascius[57]) living on the coast near the foot of the volcano explaining that her party could only get away by sea and asking for rescue. [23] A rain of ash fell, causing Pliny to shake it off periodically to avoid being buried. This fairly small eruption took place because of a new lava dome being formed and a 2.5 magnitude earthquake. Vegetation on the slope dies off during eruptive periods because of the volcanic gases. In the late summer or autumn of 79 AD, Mount Vesuvius violently spewed forth a deadly cloud of super-heated tephra and gases to a height of 33 km (21 mi), ejecting molten rock, pulverized pumice and hot ash at 1.5 million tons per second, ultimately releasing 100,000 times the thermal energy of the atomic bombings of Hiroshima and Nagasaki. The volcanoes of Italy, including Mount Vesuvius near Naples and Mount Etna on Sicily, were formed as a result of the subduction of the ancient oceanic lithosphere of the Tethys beneath the Calabrian arc, which only recently collided with the rest of Sicily and the southern part of the Italian… Some paintings excavated in Pompeii and Herculaneum represent the mountain as it looked before the eruption of 79 ce, when it had only one peak. From the 1631 eruption until 1944, there was a comparatively small eruption every few years, emitting 0.001–0.01 km³ of magma. The lowest temperatures were in rooms under collapsed roofs. Vesuvius was a name of the volcano in frequent use by the authors of the late Roman Republic and the early Roman Empire. age of volcano =, 25,000 years ago: Vesuvius started forming in the Codola. The first funicular cable car on Mount Vesuvius opened in 1880. The products formed from the eruptions like ash, solidified lava, rocks and pyroclastic flows build up layer by layer until the volcano reaches thousands of meters tall. It was at this time that Mount Vesuvius erupted during the Second World War, in March 1944. There has been 75 years of repose since the last eruption of Mt. Mount Vesuvius is caused by the African plate sinking underneath the Eurasian plate which therefore created a convergent boundary in the Bay of Naples, Italy. Thousands of people died when lava, ashes, and mud buried the cities of Pompeii , Herculaneum, and Stabiae. Historians have learned about the eruption from the eyewitness account of Pliny the Younger, a Roman administrator and poet. I hope ou do well on your paper. The oldest dated rock from the volcano is about 300,000 years old. Many scholars since then have offered an etymology. [27] On occasion, eruptions from Vesuvius have been so large that the whole of southern Europe has been blanketed by ash; in 472 and 1631, Vesuvian ash fell on Constantinople (Istanbul), over 1,200 kilometres (750 mi) away. Mount Etna: Plate Tectonic Setting. These were accompanied by additional light tremors and a mild tsunami in the Bay of Naples. Because magma is less dense than the solid rock around it, it became pushed upward, finding a weak place at the Earth's surface. The explosion of Mount Tambora is the largest ever recorded by humans, ranking a 7 (or "super-colossal") on the Volcanic Explosivity Index, the second-highest rating in the index. Since the eruption in 79 AD, Vesuvius has erupted more than 50 times. Mount Vesuvius is approximately 17,000 years old. The ruins of Herculaneum, with (in the background) the town of Ercolano and Mount Vesuvius, Italy. [40] In the surviving copies of the letters several dates are given. Let us know if you have suggestions to improve this article (requires login). Mount Vesuvius as formed when the african plate sub ducted underneath the eurasian plate, the african plate then became heated because of friction until it had melted forming magma. The collapse of the Plinian columns on the second day caused pyroclastic density currents (PDCs) that devastated Herculaneum and Pompeii. Geography of Mount St. Helens Compared to other volcanoes in the Cascades, Mount St. Helens is fairly young geologically speaking because it was formed only 40,000 years ago. Scientific study of the volcano did not begin until late in the 18th century. [45], The Romans grew accustomed to minor earth tremors in the region; the writer Pliny the Younger even wrote that they "were not particularly alarming because they are frequent in Campania". Pliny's uncle Pliny the Elder was in command of the Roman fleet at Misenum, and had meanwhile decided to investigate the phenomenon at close hand in a light vessel. The fertility of the soil in this region is attributed to the deposition of volcanic materials rich in minerals which are … Mount Etna is an unusual volcano in that most of the world's volcanoes occur on constructive and destructive plate boundaries while Etna is formed on a unique boundary between two continental plates, the European and the African plates, which are pushing towards each other due to convection currents in the mantle beneath the Earth's crust, and will eventually eliminate the Mediterranean. The most famous eruption occurred in 79 A.D., when Vesuvius destroyed the nearby Roman cities of Pompeii, Herculaneum and Stabaie. Mount Fuji, the tallest mountain in Japan, was formed by a series of volcanic eruptions that occurred over approximately the last 100,000 years. Additional blasts reinstituted the column. Compasses show four directions - north, east, south and west. An observatory was opened in 1845 at 1,995 feet (608 metres), and in the 20th century numerous stations were set up at various heights for making volcanologic measurements. Two stages could be observed: quiescent and eruptive.

The dates of the earthquakes and of the eruption are contingent on a final determination of the time of year, but there is no reason to change the relative sequence. The flows were rapid-moving, dense and very hot, knocking down wholly or partly all structures in their path, incinerating or suffocating all population remaining there and altering the landscape, including the coastline. gee, mount vesuvius was a volcano, and kept going off and on, forever and ever, until it became as large as it was. [29] The area has been subject to volcanic activity for at least 400,000 years; the lowest layer of eruption material from the Somma caldera lies on top of the 40,000 year‑old Campanian ignimbrite produced by the Campi Flegrei complex. It’s formed of two volcanoes! What does the phrase “Ring of Fire” refer to? Plaster casts of people who died in the city of Pompeii during the 79 AD eruption of Mount Vesuvius . [62] What percentage these numbers are of the total dead or the percentage of the dead to the total number at risk remain completely unknown. The volcano was then quiet (for 295 years, if the 217 BC date for the last previous eruption is true) and was described by, It erupted again in 203, during the lifetime of the historian, In 472, it ejected such a volume of ash that ashfalls were reported as far away as, The eruptions of 512 were so severe that those inhabiting the slopes of Vesuvius were granted exemption from taxes by, Further eruptions were recorded in 787, 968, 991, 999, 1007 and 1036 with the first recorded, Vesuvius entered a new phase in December 1631, when a major eruption buried many villages under lava flows, killing around 3,000 people. Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree.... Mount Vesuvius rising above the ruins of the ancient Roman city of Pompeii. Subsequently, the cloud collapsed as the gases expanded and lost their capability to support their solid contents, releasing it as a pyroclastic surge, which first reached Herculaneum but not Pompeii. There is access by road to within 200 metres (660 ft) of the summit (measured vertically), but thereafter access is on foot only. The eruptions vary greatly in severity but are characterized by explosive outbursts of the kind dubbed Plinian after Pliny the Younger, a Roman writer who published a detailed description of the AD 79 eruption, including his uncle's death. [72], Ongoing efforts are being made by the government at various levels (especially of Campania) to reduce the population living in the red zone, by demolishing illegally constructed buildings, establishing a national park around the whole volcano to prevent the future construction of buildings[72] and by offering sufficient financial incentives to people for moving away. It formed upon the site of a previous volcano. [11], The Romans regarded Mount Vesuvius to be devoted to Hercules. After each eruption, the size of the cone changes, according to Encyclopedia Britannica. Test your knowledge of volcanoes with this quiz. At some time in the night or early the next day pyroclastic surges in the close vicinity of the volcano began. [48] The magnetic study revealed that on the first day of the eruption a fall of white pumice containing clastic fragments of up to 3 centimetres (1.2 in) fell for several hours. The eruption ejected a cloud of stones, ashes and volcanic gases to a height of 33 km (21 mi), erupting molten rock and pulverized pumice at the rate of 6×105 cubic metres (7.8×105 cu yd) per second,[6] ultimately releasing 100,000 times the thermal energy released by the atomic bombings of Hiroshima and Nagasaki. What is located around Mt Etna? Sub-Plinian eruptions producing about 0.1 cubic kilometres (0.024 cu mi), such as those of 472 and 1631, have been more frequent with a few hundred years between them. 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. [76] The summit of Vesuvius is open to visitors and there is a small network of paths around the volcano that are maintained by the park authorities on weekends. This structure has given its name to the term "somma volcano", which describes any volcano with a summit caldera surrounding a newer cone. Vesuvius was active from 1913 through 1944, with lava filling the crater and occasional outflows of small amounts of lava. Vesuvius is part of the Campanian volcanic arc, a line of volcanoes that formed over a subduction zone created by the convergence of the African and Eurasian plates. Severe paroxysmal (suddenly recurring) eruptions, concluding an eruptive stage, occurred in 1660, 1682, 1694, 1698, 1707, 1737, 1760, 1767, 1779, 1794, 1822, 1834, 1839, 1850, 1855, 1861, 1868, 1872, 1906, 1929, and 1944. The crust material became heated until it melted, forming magma, one kind of liquid rock. Magna is called lava when it breaks through the earth's crust. The volcano then entered a stage of more frequent, but less violent eruptions, until the most recent. Still higher, on the slopes of the great cone and on the inner slope of Mount Somma, the surface is almost barren; during quiescent periods it is covered by tufts of meadow plants. How Mount Kilimanjaro was formed. It can be explosive like its most famous eruption in August 24, 79 A.D. which caused ashfalls, volcanic impact, and mudflows onto Pompeii and Herculaneum, or nonexplosive like in May 1, 1855 which a lava flow invades Massa and San Sebastiano. It seems that for Vesuvius, the amount of magma expelled in an eruption increases very roughly linearly with the interval since the previous one, and at a rate of around 0.001 cubic kilometres (0.00024 cu mi) for each year. Mount Vesuvius is located on the Gulf of Naples in Campania, Southern Italy. Although a relatively young volcano, Vesuvius had been dormant for centuries before the great eruption of 79 ce that buried the cities of Pompeii, Oplontis, and Stabiae under ashes and lapilli and the city of Herculaneum under a mudflow. These volcanoes are all part of the same subduction zone which was created by the Eurasian and African tectonic plates converging. The writer Pliny the Younger, who was staying at a place west of Naples, gave an excellent account of the catastrophe in two letters to the historian Tacitus. The top of most maps is north and a compass can be used to find which direction north is. Some of the others volcano also found in this arc are Stromboli, Vulcano, Campi Flegrei (Phlegraean Fields) and Mount Etna. The Latins also competed for the occupation of Campania. The former was pushed beneath the latter, becoming pushed deeper into the Earth. The plan assumes between two weeks' and 20 days' notice of an eruption and foresees the emergency evacuation of 600,000 people, almost entirely comprising all those living in the zona rossa ("red zone"), i.e. "Funiculì, Funiculà", a Neapolitan language song with lyrics by journalist Peppino Turco set to music by composer Luigi Denza, commemorates its opening. It was collected from a well drilled near the volcano and was probably part of the Somma volcano. Many villages on the slopes of the volcano were destroyed, about 3,000 people were killed, the lava flow reached the sea, and the skies were darkened for days. One of this, named Colle Umberto, formed between1895 and 1899 in the area between the cone and the Observatory. Vesuvius in 2013 was 4,203 feet (1,281 meters) tall. Mount Vesuvius is a composite volcano. March 1944 Background Information of Mount Kilimanjaro Kilimanjaro was formed about 1 million years ago by a series of volcanic movement’s along the Great Rift Valley. Though Pliny the Elder died, his friends ultimately escaped by land.[58]. Mount Vesuvius was formed in a cataclysmic volcanic eruption in the year 79. Different perspectives and the damage caused to the local villages were recorded by USAAF photographers and other personnel based nearer to the volcano.[69]. Further tremors near dawn caused the population to abandon the village and caused disastrous wave action in the Bay of Naples. When did Mount Vesuvius erupt? After the eruption of 1906, forests were planted on the slopes in order to protect inhabited places from the flows of mud that usually occur after violent eruptions, and in the fertile soil the trees grew rapidly. Finding a weak spot at the Earth's surface, it broke through, thus forming the volcano. Since AD 79, the volcano has also erupted repeatedly, in 172, 203, 222, possibly in 303, 379, 472, 512, 536, 685, 787, around 860, around 900, 968, 991, 999, 1006, 1037, 1049, around 1073, 1139, 1150, and there may have been eruptions in 1270, 1347, and 1500. Vesuvius is but one of the recent/current active volcanoes in that arc (e.g Etna, Stromboli, Volcano etc.) The remains of Pompeii lay in an impressive state of preservation for … Many are either extinct or have not erupted for tens of thousands of years. It is only 9 km east of Naples and it's one of the most well known active volcanoes in mainland Europe. Mount Vesuvius is a composite volcano because its eruptions vary often from pyroclastic material to lava flows. This article was most recently revised and updated by, https://www.britannica.com/place/Vesuvius, Oregon State University - Volcano World - Vesuvius. Scientific knowledge of the geologic history of Vesuvius comes from core samples taken from a 2,000 m (6,600 ft) plus bore hole on the flanks of the volcano, extending into Mesozoic rock. ‘ main peak ’ is named Vesuvius, which Pliny likens to sheet lightning, but scientists ways!
