Recommended: Effect of volcanic eruptions
Introduction:
Mount Vesuvius is one of history’s most recognizable Volcanoes, as each of its eruptions have gone down as a significant event in geologic history. The events that transpired during and after these eruptions have shaped the way scientists and people view the sheer power that these volcanoes possessed. This report will take a look at Vesuvius’ most prolific eruption in 79 AD. The geologic setting of the mountain, precursor activity, and the impact the eruption had on the surrounding populations and towns will all be detailed. Along with these details, this report will also look at the further history of Vesuvius’s explosive past by detailing its eruption cycle. Finally, the current state of Vesuvius and the possible danger the current population living near the mountain could face should it erupt explosively again.
1. Background on Vesuvius
Mount Vesuvius or Somma-Vesuvius, is located in the Province of Naples in Western Italy. It is part of an area known as the Campainian volcanic arc, which is a chain of volcanoes that formed over a subduction zone. (Geology.com) Subduction zones are regions in the Earth’s crust where two plates, in this case, the African and Eurasian plates converge and push one another. This push forces the lighter plate further into the Earth’s bowels, leading to that rock melting under higher pressure and temperatures, thus forming Magma. This Magma rises to the surface, forming volcanoes such as Vesuvius and it’s counterparts along the Campanian arc. (USGS Earthquake glossary).
The actual eruption of Vesuvius was of the explosive nature. The catastrophic eruption in 79 AD took place in a period that is estimated to have unfolded over 25 hours and took place in two stages (Museum tim...

...uvius was that of Herculeam. Initially, the town escaped any major damage from ash fall as it was upwind from the volcano. (Natural history of Pompeii) Unlike Pompeii, Herculeam’s demise was much more swift and potent.
The end of Herculeam would come at the mercy of red hot mudflows and steam spills from the volcano. As at around 1 AM on August 25th, this combination would reach Herculeam and scorch everything in it’s way. (Museum timeline) Later on, the initial pyroclastic flows that failed to reach Pompeii would in fact reach Herculeam, burning anyone who survived the initial mudflow alive. (BBC)
The entire reigion was obliterated. What was one a thriving cluster of towns were reduced to shambles. People, animals, vegetation are all wiped out. Herculeam was scorched and Pompeii was buried to the point where all that remained were the very highest of walls.
Sebastian Pether’s piece of work called The Eruption of Vesuvius (1835) combines the silver watery reflection of the moon with the hot red molten lava that is flowing down its mountainsides. Though during Pether’s generation he wasn’t the only one to paint the well-known Mount Vesuvius, Joseph Wright of Derby also painted 30 paintings of the volcano. This art piece is currently located at the Nelson-Atkins Museum of Art. The piece is oil media on panel that is framed with a beautifully designed border, where it is hanging on a wall in the one of the rooms, with a one-dimension view. The quality of the piece owes itself to the color and lighting, which captures your immediate attention and guides the viewer through the piece.
I found this article in the GCC database. I found it extremely helpful because I found direct numbers of the devastation. All other articles could not conform the area that was effected and I have found it in this article.

Mount Vesuvius is located in the Bay of Naples in Southern Italy. Its Latitude and Longitude is 40.8224° N, 14.4289° E. It is a stratovolcano and has a height of 1277 meters (1490 feet) and base of 48 kilometers (30 miles). Mount Vesuvius has erupted over 30 times and has a repose time that can last for months or even years between eruptions. Its eruptions are explosive and is dominated by pyroclastic flows. The eruption materials are usually an ash cloud with lightening that spews out dense ash falls. The lava can shoot up to 4km into the air. The most famous eruptions of Mt. Vesuvius were in 79 A.D. which destroyed the cities of Herculaneum and Pompeii. The cities were covered in 20 feet of volcanic debris. The estimated death toll was over 1000 people. The
At first Herculaneum was protected by a westerly wind, but as the energy of the blast waned and the Colum of material could no longer be supported above the volcano it collapsed and a giant surge cloud of hot ash swept down the western flank and scorched and suffocated the people of Herculaneum. This was the first flow. In Pompeii people had survive the rock falls and were roaming the streets on top of the rubble blanket. The
Many people in Pompeii managed to escape while others did not escape before the eruption happened. A volcano named Mt.Vesuvius erupted in the city of Pompeii located in Naples,Italy. It was a non-active volcano that suddenly became active years later and erupted. Some of the pompeians escaped while others did not. About 20,000 people lived in Pompeii when the eruption happened. The eruption wiped out the whole city, leaving 15-30 feet of ash behind killing about 2,000 people who did not escape.(39 )
The city has remained intact until the present day because of being buried so quickly. Not only are its buildings complete but also the contents inside the houses and shops have been preserved. This provides a fascinating picture of "daily" life in Pompeii. The walls of the houses are covered with electoral propaganda messages or risqué jokes aimed at particular citizens. The signs on the shop doorways indicate the activity carried out there or the name of the owner. The workshops and utility rooms found provide evidence of the daily routine performed by workmen and slaves.
Earth has physically changed millions of times due to moving tectonic plates which has formed our planets mountains; altering the way our environment looks. Volcanoes, (formed when magma from the upper mantle heads to the surface, causing the land to rise) are one of nature’s finest spectacles. These geographical forces have erupted many times; from small-scale eruptions to cataclysmic ones; making them a force to consider about. Therefore the past is useful in predicting possible future eruptions as in terms of the effects they can have on civilisation, they are unpredictable in what they can produce.
BOOM!, BOOM!, BOOM!, explosions, ash, carbon dioxide and, magma going everywhere burning buildings and people, starting to kill people every second. This can only mean one thing the volcano is erupting and a bad one, this volcano is called Mount Vesuvius this eruption covered Pompeii with layers of ash and hardened magma until Pompeii was rediscovered as the result of intentional excavations in 1748 by the Spanish military engineer Rocque Joaquin de Alcubierre. There is a fiction and nonfiction version of the story of pompeii one story is by Louis Untermeyer The Dog of Pompeii is fiction and one other story by Robert Silverberg called Pompeii which is nonfiction.
Mount Vesuvius is a volcano near the Bay of Naples in Italy. The volcano is hundreds of thousands of years old. It has erupted over 50 times. The most known eruption took place in 79 A.D. In 79 A.D. Mount Vesuvius erupted onto the city of Pompeii. One witness wrote that the volcanic ash “poured across the land” and covered the city in “a darkness… like the black of closed and unlighted rooms.” When the volcano erupted it killed around 2,000 people. Even though the volcano covered the city in a thick layer of volcanic ash and lava, in 1748 a group of scientist found that after you dug through the layer of ash the majority of the city is still intact. This wasn’t the first major eruption the volcano has dished out. In 1780 B.C. it erupted and
They say even though Herculaneum was closer to Vesuvius there was not as much damage to show as in Pompeii. Pompeii was absolutely devastated after the eruption. There was volcanic stone found all over the city. The people of Pompeii were killed in many different ways, some from the ash cloud that spread throughout the city. Others died from earthquakes and being burned alive by the lava. The ones that were killed by the lava were most likely late from trying to grab whatever they thought was most useful and thought they absolutely needed after the volcano. But this was not
Since it was freed from its ash coffin, Pompeii has not fared well. The millions of yearly visitors, who flock to the site to see firsthand the living legend that is Pompeii, are causing erosion in a way that was not anticipated. The balance that had kept the city protected for so long has been disturbed, and it is now a victim of an unacceptable degree of damages.
Some people say that if the volcano of Pompeii had not erupted than people would be able to know more about Pompeii. I do think that it is true because if it had not erupted the town would not have completely transformed from all of the damages. Another, reason is because the town was buried in lava and things that had come out from the volcano. In the story it said that after all of the damage had been done if anybody came back to see the town it would have completely transformed and nothing would even look the same. The text states, “ In the days that followed, residents who returned hoping to find their city would have been lost in an unfamiliar.” What the author meant to say by this is that if the volcano had not erupted and completely
It not only destroyed the homes of the people who lived there but it also messed with their head. It caused then to think differently and jump to conclusions. Though they eventually recovered the emotional and mental damage stuck with them.
10th of June soon after midnight. Mt Tarawera light up like fireworks. BOOM! Molten rock cam flying out of the crater. People as far as Blenheim could hear this thunder like noises but had no idea what it could be. Although the people of Rotorua knew exactly what has happening Mount Tarawera was erupting! The Mt. Tarawera eruption was the largest eruption in New Zealand for 800 years.
