Yellowtone Caldera Research Paper

The Yellowstone volcano is very active volcanic system which requires much observation. The geysers, mudd pots, hotsprings and steam vents are all examples of the heat from molten rock of a volcano. For many years the Yellowstone volcano could not be located. There is not obvious signs of a volcano, but scientists looked for other clues. Rhyolite is present in a location that has pinetress and many mosquitoes can be found due to the lakes that have formed. Rhyolite is a very violent eruption, due to the high silica content,  it flows slowly, like honey, and tends to pile up and form lava

Volcanoes are natural disasters that the human race can recover from eventually. Though it is true that every volcano eruption has cons , but on the positive side it helps the environment. The volcanoes main effect is to provide nutrients to the surrounding soil. Volcanic ash often contains minerals that are beneficial to plants, and if it is very fine ash it is able to break down quickly and get mixed into the soil. Volcano gases are a main source of water and most of the atmosphere.

A volcano is an earth hazard that occurs on faults between tectonic plates on a destructive boundary and an eruption is a natural disaster. A primary impact happens immediately after the disaster and before any response like death or collapsing or destruction of buildings. A secondary impact occurs later after the disaster, such less farm produce or a reduction in tourism. The severity of these impacts will differ considerably in a MEDC and LEDC where volcanic eruptions have taken place. These may be seen in the Mount St. Helen volcano eruption as well as in the Iceland volcanic eruption. They may also

Yellowstone National Park is one of the largest and oldest national parks in American history. Yellowstone was the first park to be protected by private investment on March 1, 1872, and the first to be put under the jurisdiction of the National Park Service in 1918, no doubt due to its unique and inspiring landscape and geothermal features. In fact, Yellowstone National Park is home to half of the world’s total hydrothermal features. These awesome attractions draw an incredible amount of visitors, an average of two to three million each year, to Yellowstone’s immense landscape. The park has a total size of 28,125 square miles, is found in three distinct states, and is considered to be one of the largest

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.

Volcanos are beautiful yet discursive. They may have different effects on towns but some are similar, and some are different. Some may have an effect on both people and cities and the people's mindsets may change on their beloved homes.

Another physical factor is snow; if a volcano is snow capped, like Eyjafjallajokull, then the lahars and flash floods become a greater hazard. The flooding in Iceland in 2010 caused 700 people to be evacuated. Without the snow then lahars and floods may not be a problem at all.

Martin, Sean. “Mt St Helens: Fears Volcano Responsible for Deadliest Eruption in US History Is RECHARGING.” Express.co.uk, Express.co.uk, 8 June 2017, www.express.co.uk/news/science/814620/Mt-St-Helens-LATEST-volcano-recharging.

On May 18th, 1980 one of the worst volcanic eruptions occurred in the United States. Triggered by an earthquake, Mount St. Helens erupted in Washington State at 8:39am. According to the National Oceanic and Atmospheric Administration, it was "the deadliest and most economically destructive event in the history of the United States." There were many effects from this terrible, natural event. People, animals, and the environment were all effected.

After more then 40,000 years of activity, one would expect that people would no longer live in the surrounding shadow of Mt. St. Helens. But regardless, many towns and cities sit inside of a zone that would face destruction if a large eruption took place. In 1980 Mt. St. Helens erupted and caused the loss of many lives and the destruction of thousands of miles of land and property. Following the eruption, the volcano has stayed extremely active. In 2004 it erupted again, building a new lava dome and sending ash and steam into the atmosphere. Since then, seismologists and volcanologists have recently discovered pockets of magma rising and that another eruption may occur soon. Even though the people of Washington know that an eruption could cause widespread devastation they continue with their lives, doing little to prepare for the potential disaster.

Mauna Loa volcano. Mauna Loa is an active, large, and dangerous volcano in the world.this volcano can cause more than one damage. Mauna Loa affects people’s lives, and damages lands. Mauna Loa is a magnificent force of nature.For centuries Mauna Loa has captivated many discoverers and scientists all around the world.But some, however got injured by Mauna Loa and didn’t study its parts.One discoverer however actually discovered it somehow.This volcano is very dangerous and it can damage 1 small village.

Another well-known geological phenomenon in the United States is Yellowstone Park. Yellowstone is an extraordinary example of a caldera which is defined as “a volcanic crater that has a diameter many times that of the vent and is formed by collapse of the central part of a volcano or by explosions of extraordinary violence”(USGS). Since Yellowstone is a caldera, it means that there had been previous volcanic eruptions in this area and in this case two eruptions. The first explosion happened over 2,000,000 years ago because the composition of the magma contained vast traces of explosive matter that caused the eruption (USGS). The second incident happened around

The third eruption happened about 640,000 years ago, and spewed 240 cubic miles of material. This third eruption created the third and largest of Yellowstone’s calderas, Yellowstone Caldera, which is 30 by 45 miles in size. The pyroclastic lava flows from this eruption formed the north wall of the caldera and are visible from the south-facing cliffs east of Madison. (Solcomhouse) This third eruption is said to have vaporized an entire mountain range. Smaller eruptions have also helped to shape Today’s Yellowstone, such as one that occurred 174,000 years ago and created what is now the “West Thumb” of Yellowstone Lake. (National Park Service) Many sources say that a catastrophic eruption, such as those that have formed the three calderas at Yellowstone, is unlikely during the next several hundred years, but if one such eruption did occur it would devastate much of the United States and would have the potential to alter the global climate.

Lumps of Lava cool into solid rocks as they fly through the sky, forming rounded chunks that can be also known as bombs, while pieces with corners and sharp edges are named blocks. Both bombs and blocks can cause a great deal of damage. As the volcano begins to burst, the sky fills with choking, smoky powder, while it starts raining lava, and rock. The air warmed quicker than when you pour kerosene on a fire, with a sound so loud it circled the earth four times, red hot lava flows down the side of the volcano and magma spews out the top. The only taste in my mouth is the smoke coming from the lava, as the gas in the air turned all my silver jewelry black. I feel very frightened knowing this is such a normal thing to happen in different

How volcanoes affect people and environments? A volcano is a mountain or hill having a crater or vent through which lava, rock fragments, hot vapor, and gas are in. Volcanoes can change the weather. They can cause rain, thunder and lightning. Volcanoes can also have long-term effects on the climate, making the world cooler.
