Similarities Between Mount Vesuvius And St. Helens

Let’s begin with Mount St. Helens which is located in the pacific northwest of the United States. To be more specific it is located in Washington State and is a part of the Cascade mountain range that spans from California to Canada. It is a composite volcano, which has steep sides that are formed by alternating layers of lava

Volcanos are deadly, can form on islands or mainland, and can destroy mountains and cities. Volcanos commonly form from holes in the earth containing magma. When pressure builds up in these magma chambers, they explode resulting in magma and rock catapulting out into the air. As these volcanoes repeatedly explode, they leak magma, which runs down the side of the volcano. Eventually, the lava cools and transforms into solid rock, building up the volcano to mountain size. An example of giant volcanic eruptions is the Pompeii disaster in 79AD, when Mount Vesuvius erupted and destroyed all of Pompeii. Another example includes, the 1980 eruption of Mount St. Helens in Washington state, which destroyed the whole mountain. Volcanos

There are many differences between the volcanoes for example the explosivity of the two volcanoes most recent eruptions are completely different Kilauea is almost constantly flowing and has virtually no explosions at all it also has low viscosity lava flows running from it constantly where as MT st Helens is completely different in MT st Helens most devastating eruption in 1980

Volcanoes are one of the most destructive, yet, most beautiful things on Earth. They can make a famous city choke in its own ashes in one day, like Pompeii. Or they can turn a once damaging mountain into a graceful and peaceful home for new life, like Mount St. Helen’s. All volcanoes are unique, and no two are the same. Some erupt differently than others, some look different than others, and all are located in different spots all over the world. I learned this while completing the project and the five volcanoes I researched are examples of my discoveries. The five volcanoes I researched were Mount Hood, Mount Mageik, Long Island, Mount Muria, and Las Pilas.

There are two very well known and pretty much legendary volcanoes, Mount Vesuvius and Mount St Helens. They may seem different and they are, but they are the same too, for instance both Mount vesuvius and Mount St Helens are both stratovolcanoes,they’re also both “claimed to be complex volcanoes”. Both volcanoes had their major eruption after lying dormant for more than 10 years, and their major eruptions caused more than half of pompeii and and to go to rubble. Both also erupted more than once and changed civilization and most of all the people’s perspectives on the “Smoking Mountains” all stated on geology.com. These volcanoes also both destroyed civilization and they both had a major impacted on their cities and towns they destroyed. In geogly.com states that both volcanoes

On May 18, 1980 Mt. St. Helens erupted, and wrecked havoc on its surroundings through the debris avalanche, the lateral blast, the mudflows, and the ash that traveled halfway across the United States. It all began in March of 1980 when a 4.2 earthquake and 174 aftershocks let the world know that the volcano had woken

Mount Vesuvius, like most volcanoes was created through the interactions between continental plates. Mount Vesuvius was formed 17,000 years ago through the convergence of two tectonic plates, the African plate and the Eurasian plate. Vesuvius is located above a subduction zone in which the African plate is being subducted by the Eurasian plate (Ball). The African plate has been subducted at a rate of about one inch every year. This type of interaction between converging plates is responsible for creating volcanoes (Figure 1). This created a submerged deep ocean volcano in the Bay of Naples. Later, Mount Vesuvius emerged from the ocean as an island. However, over time it was connected to the mainland due to buildup of deposits from its eruptions.

The volcano is actually a volcano inside of a volcano. When scientists studied the structure they pointed out its two different cone shaped tops spread about three miles long of a valley in between. They then stated that it was two volcanoes one inside the other in some geographic way. The eruption in 79AD was the first recorded eruption for history. Mount Vesuvius is in the Campanian volcanic arc along with Vulcan and some others

Mt. St. Helens erupted on May 18, 1980 and it is said to be the most disastrous volcanic eruption in United States history. There had been months of build up beneath the surface along with a massive bulge growth on the side of the mountain. It began when an earthquake struck beneath the north face of Mt. St. Helens, which set off the biggest landslide to ever happen in the US. Seconds later there was an explosion of the north side of the volcano generating a huge cloud followed by lightning. The large landslide was followed by several lahars (mud flow) and pyroclastic flows (hot gas and volcanic matter).

Before May 1980, Mount St. Helen in Washington State ha been quiet for over a hundred years. It had been calling "the Fuji of America " because it's symmetrical cone resembled the famous volcano in Japan. It's massive eruption on Sunday, May 20, 980, changed that shape. Mount St. Helens lost 3.7 billion cubic yards of rock. Volcanic ash was send fifteen miles into the air, and very hot winds blew in all directions. Two hundred thirty square miles of forest were flatten. Seventy percent of the snow and ice on the mountain melted, causing an enormous landslide of mud, volcanic ash, rocks, and trees to speeding down the mountain at 500 miles per hour. In the eruption, fifty-seven people lost their lives, some as far away as thirteen miles from the mountain. Most of them were scientists, loggers, and journalists.

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

Would you rather have been in Pompeii or Washington during their eruptions? It would be a hard choice because they were both destructive. They are kinda alike in some ways. However, they were both very different from each other. From Pompeii, Italy to Skamania County, Washington are two of the deadliest volcanoes.

Mount Vesuvius developed inside the caldera of an older volcano. This volcano was known as Monte Somma. Monte Somma became active around 400,000 years ago. Only the northern side of Monte Somma is left, creating a wall-like ridge around the northern edge of Mount Vesuvius. This feature can be observed today at the site of Mount Vesuvius. The development of Vesuvius produced a volcanic complex consisting of the two volcanoes. (De Boer and Sanders, 2002)

Earthquakes and volcanoes are both similar in the fact the earthquakes can cause volcanoes to form or even erupt, but the severity of their damage is caused by different factors and result in different outcomes. The earth can be structurally compared to an egg. It has a large hot core, a thick layer of soil, and then a thin layer of tectonic crust
