Transcript of Mount Vesuvius
By: Maya Gonzalez
What is Mount Vesuvius?
Mount Vesuvius is classed as a stratovolcano because its eruptions usually involve explosive eruptions as well as pyroclastic flows. This volcano is best known for its eruption in AD 79 that led to the burying and destruction of the Roman cities of Pompeii, Herculaneum and several other settlements.
Thanks for watching
Why and how did it erupt?
Volcanoes erupt whenever extreme pressure builds in the mantle, along fault lines (openings or cracks in weak spots in the earth’s crust) an eruption is likely to happen next. During an eruption, magma materials (soon to become lava) gush out through spaces in the crust to the surface. When Mount Vesuvius erupted, that eruption spewed a cloud of stones, ash and fumes to a height of 33 km (20.5 mi), spewing molten rock and pulverized debris at the rate of 1.5 million tons per second, ultimately releasing a hundred thousand times the thermal energy released by the Hiroshima bombing. An estimated 16,000 people died due to hydrothermal pyroclastic flows. The only surviving eyewitness account of the event consists of two letters by Pliny the Younger to the historian Tacitus.
Why was it so popular?
Mt. Vesuvius has erupted many times since and is the only volcano on the European mainland to have erupted within the last hundred years. Today, it is claimed 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.
Where are volcanoes typically located
Mt. Vesivius is located in the Gulf of Naples, Italy, about 5.6 mi east of Naples and a short distance from the shore.

How do weathering,erosion and deposition come into play?
The strength of the volcano is determined at least in part by what kind of rocks and other matter makes it up. That is where weathering comes into play. (rocks blow away and settle only to get pushed to the volcano's sides and base.) Volcanoes can cause erosion or they can be eroded. When the volcano erupts, the haze can cause snowstorms and erode rocks. The volcano can also get smaller due to erosion. Mt. Vesuvius must have been bigger 2000 years ago.
How was it constructive and destructive?
It was constructive because when it erupted, the lava flowed down and hardened to make mountains and rock structures. It was destructive because when it erupted, it destroyed a very big city. This volcano has erupted about 200 times but pompeii was the most famous.
Why did it erupt
Mt. Vesuvius erupted because of density and pressure. The lower density of the magma relative to the surrounding rocks causes it to rise (like air bubbles in syrup). It will rise to the surface or to a depth that is determined by the density of the magma and the weight of the rocks above it.
Were there any solutions or safety precautions they could have took
There were no solutions but they should have saw the signs coming for years. Like there was a big earth quake 14 years before. Also you could smell the sulfur. The only thing they could have done is run when they saw and smelled the signs.

How long did it take for the city of Pompeii to recover?
Unfortunately the city of Pompeii got buried from the volcano erupting and the lava cooling. If you didn't die from the eruption, you were killed several minutes later by the poisonous gas coming out of the volcano. Around 25,000 people died. So there was no government or financial strain. The long term effect was the city is now buried
