Mt.Vesuvius and its 79 AD Eruption Essay

Cinder cone volcanoes is a type of volcano that is merely the same as a shield volcano but the difference is that the cinder cone volcano is higher on one side then on the other side it is lower.These type of volcanoes can also be called a scoria volcano so you don't always have to say cinder cone volcano you can call it a scoria volcano so people can be more interested in what you are talking about or that can say "what is a scoria volcano?".These type of volcanoes erupt when lava that is highly charged with gas bubbles erupts from a vent under pressure it tends to shoot straight up into the air, this effect is called a fire fountain. The most likely places you can find cinder cone volcanoes are in United States and Canada they have the most cinder cone that we know of.

Some volcanoes are more dynamic than others since some volcanoes lie on plate limits that move much of the time which adds more weight to the magma chamber where the majority of the

In the article "Mount Vesuvius" it starts with everyone thinking that it was a beautiful day, till the mountain would erupt. But mt. vesuvius is no mountain it is a volcano, a very deadly volcano. Even though this volcano did not show very many signs of erupting it still did that day. I chose this article because it has a lot of detail so I can write more about this article. Almost everyone died that day in Pompeii because there was no way to escape.

Throughout the first eight weeks of Physical Geology I, I have learned more about the Earth, how it works, and natural disasters than I have in my entire educational career. We have analyzed everything from the different types of rocks to several different natural disasters such as volcanoes and earthquakes. However, one thing in particular caught my attention and fascinated me through its sheer power and destruction. Volcanoes are intriguing, and they have the force and destructiveness to wipe out an entire population.

Some volcanoes happen often but others haven't erupted for a long time. Some volcanoes are found are the Pacific Ocean. Others are found around the Atlantic and Indian Ocean.Volcanoes are mountains that are coned shaped. Magma is made beneath the Earth's crust and extreme pressure makes the magma rise, it breaks through weak spots and comes out of mountains which makes it a volcano. Volcanoes explosive chart is zero to eight. Zero means non explosive and eight means mega colossal.

The magma is known to block the vents of the volcano, so that is why the eruption is hazardous. Composite volcanoes usually have andesite lava.There are three main types of lava/magma that volcanoes have: andesite, dacite, and rhyolite. Andesite lava/magma usually is dense and has a thick consistency. It consists of “quartz and feldspar minerals”.The magma flows out through a pipe called the main

Volcanoes large volcanoes that are built almost completely from lava are called “shield volcanoes” They are named for their sloping sides which

Volcanoes exist all around the world.A volcano is a place where hot ash,gases,and molten rock deep underground erupt. Volcanoes can be dangerous for many reasons for example hot ash,lava,cinders,and mud. The magma chamber carries magma up into the pipe and out the crater or top vent. Volcanic eruptions can differ in their violence for example some volcanoes are fast moving lava or pahoehoe or slow moving lava aa. Some volcanoes erupt water vapor carbon dioxide and some volcanoes can erupt 60 ton bricks or cinders.

Mount Vesuvius, erupted on August 24 , 79 AD and killed thousands of people in the Roman cities of Pompeii and Herculaneum. This happened after a series of earthquakes and split the plate under the volcano, causing it to explode. The people had enough time to escape but did not as earthquakes happened in that area, all the time and they thought nothing of what might happen.

Mount Vesuvius is the only active volcano in mainland Europe and is considered one of the most dangerous volcanoes in the world! It’s elevation is over 4,000 feet (1,219 m) and the distance around the base is 30 miles (48.3 km). This humongous mountain is located in Ottaviano, Metropolitan City of Naples, Italy, which is now known for its ancient castles and history.

No one really knows how volcanoes came to be but we know what is inside one. An example of this would be in the article Volcanoes –

There are three types of volcanoes on earth. They are composite, cinder cone and shield volcanoes. They are all over the world and depending on what kinds of volcanoes they are they would be in different areas because some volcanoes have little lava and some have a lot that can be very dangerous if they were to irrupt.

Volcanoes may affect the way the environment is and the way people eat and make a living. For example the eruption of Mount Vesuvius affected the region by providing the soil with nutrients. The soil is now rich and filled with plants.“ By improving moisture and retention, they make soil easier to till for

On August 24th AD 79 Mount Vesuvius violently erupted and buried the cities of Pompeii and Herculaneum. The eruption of the volcano was recorded by one of the only surviving eyewitnesses Pliny the Younger. He described the start of the eruption like this: “On August in the early afternoon, my mother drew his attention to a cloud of unusual size and appearance…its general appearance can best be expressed as being like an umbrella pine, for it rose to a great height on a sort of trunk and then split off into branches, I imagine because it was thrust upwards by the first blast and then left unsupported as the pressure subsided.” (Pliny the Younger, trans Betty Radice in August 30 1963). In the evening of the same day pumice began to fall form the sky. The streets of Pompeii and Herculaneum started to get covered by a layer of ash and pumice. The smoke from the eruption was so high that it started to block out the sun. “Ashes were already falling, hotter and thicker as the ships drew near, followed by bits of pumice and blackened stones, charred and cracked the flames.” (Pliny the Younger, trans Betty Radice in August 30 1963). Around midnight the pyroclastic surges started. A pyroclastic surge is an avalanche of pumice, rock, hot ash and volcanic gas, which rushes down the side of the volcano at 100 km/hour or faster. In the map, we can see the locations of Pompeii and Herculaneum in comparison to Mount Vesuvius. Herculaneum was 6 km from the foot of Vesuvius, whilst Pompeii

The first stage of a volcano erupting begins with some sort of blockage in the vent of a volcano. The vent lets magma and gases release without an eruption. According to Milton Kazmeyer, the vent can become blocked because of either internal or external reasons. Sometimes the blockage is due to the magma trying to flow to the surface, but it becomes too thick and viscous, and instead of escaping peacefully, it ends up plugging the vent as it ascends. Other times, the rim of a volcano collapses and fall backs into the vent, blocking it with the debris. The blockage prevents the release of gases that are trapped in rhyolitic magma, which has a high viscosity. The higher viscosity of a magma, the faster the lava will flow after eruption. A build up of rhyolitic magma prevents the release of trapped gas and the rocks then begin melting inside the Earth's crust, forming magma. The magma is lighter than the solid rocks that are surrounding and this causes it to rise and collect in magma chambers underneath the volcano (Stages of a Volcano Eruption).
