Rainier Mount Vesuvius is one of the 16 Decade Volcanoes. Mount Vesuvius has erupted many times. The famous eruption in AD 79 was preceded by numerous others in prehistory, including at least three significantly larger ones, the best known being the Avellino eruption around BC which engulfed several Bronze Age settlements.
Since AD 79, the volcano has also erupted repeatedly, in,possibly in,,aroundaround,,around,and there may have been eruptions in, and There have been no eruptions sinceand none of the eruptions after AD 79 were as large or destructive as the Pompeian one.
The eruptions vary greatly in severity but are characterized by explosive outbursts of the kind dubbed Plinian after Pliny the Youngera Roman writer who published a detailed description of the 79 AD eruption, including his uncle's death. A few times sincelandslides in the crater have raised clouds of ash dust, raising false alarms of an eruption.
Before AD 79 Vesuvius erupting. Cores were dated by potassium—argon and argon—argon dating. Vesuvius started forming in the Codola Plinian eruption. About 19, years ago: The eruptions are named after the tephra deposits produced by them, which in turn are named after the place where the deposits were first identified: The eruption was followed by a period of much less violent, lava-producing eruptions.
Several carbon dates on wood and bones offer a range of possible dates of about years in the mid-2nd millennium BC. In Maynear NolaItalian archaeologists using the technique of filling every cavity with plaster or substitute compound recovered some remarkably well-preserved forms of perishable objects, such as fence rails, a bucket and especially in the vicinity thousands of human footprints pointing into the Apennines to the north.
The settlement had huts, pots and goats. The residents had hastily abandoned the village, leaving it to be buried under pumice and ash in much the same way that Pompeii and Herculaneum were later preserved. The last of these may have been in BC.
Plutarch wrote of the sky being on fire near Naples and Silius Italicus mentioned in his epic poem Punica  that Vesuvius had thundered and produced flames worthy of Mount Etna in that year, although both authors were writing around years later.
Greenland ice core samples of around that period show relatively high acidity, which is assumed to have been caused by atmospheric hydrogen sulfide.
The volcano was then quiet for years, if the BC date for the last previous eruption is true and was described by Roman writers as having been covered with gardens and vineyardsexcept at the top, which was craggy. The volcano may have had only one summit at that time, judging by a wall painting, "Bacchus and Vesuvius", found in a Pompeian house, the House of the Centenary Casa del Centenario.
He also perceptively suggested that the fertility of the surrounding slopes may be due to volcanic activity, as at Mount Etna. He went on to describe Pompeiian pumice as having been burnt from another species of stone.
Historians have learned about the eruption from the eyewitness account of Pliny the Youngera Roman administrator and poet  who dated the eruption to August 24th.
New evidence, however, suggests that this eruption may have occurred on October 24th. Small earthquakes started taking place on 20 August 79  becoming more frequent over the next four days, but the warnings were not recognized. The black cloud represents the general distribution of ash, pumice and cinders.
Modern coast lines are shown. Reconstructions of the eruption and its effects vary considerably in the details but have the same overall features. The eruption lasted two days. The morning of the first day was perceived as normal by the only eyewitness to leave a surviving document, Pliny the Younger.
In the middle of the day an explosion threw up a high-altitude column from which ash and pumice began to fall, blanketing the area. Rescues and escapes occurred during this time. At some time in the night or early the next day pyroclastic surges in the close vicinity of the volcano began.
Lights were seen on the peak interpreted as fires. People as far away as Misenum fled for their lives. 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.
These were accompanied by additional light tremors and a mild tsunami in the Bay of Naples. By late afternoon of the second day, the eruption was over, leaving only haze in the atmosphere through which the sun shone weakly.
The latest scientific studies of the ash produced by Vesuvius reveals a multi-phase eruption. The chief energy supporting the column came from the escape of steam superheated by the magma, created from seawater seeping over time into the deep faults of the region, that came into interaction with magma and heat.
Subsequently, the cloud collapsed as the gases expanded and lost their capability to support their solid contents, releasing it as a pyroclastic surgewhich first reached Herculaneum but not Pompeii.
Additional blasts reinstituted the column.Vesuvius plc’s financial results, published reports and investor presentations.
