Volcanos are amazing and frightening geologic features of our earth. Their volcanic ash feeds the farmlands, but that same ash from a violent eruption destroys crops. There are numerous volcanic eruptions that have changed the world. These eruptions include Mt. Saint Helens, Kilauea, Pompeii, and Pinatubo. The purpose of this paper is to describe the jeopardy of a volcano in the United States.
The Yellowstone supervolcano is in Wyoming, a sparsely populated state in the American West. Yellowstone National Park is in the northwest corner of Wyoming. This volcano is underneath the park, and scientists suggest that it is capable of destroying a large amount of the nation. Scientists discovered this volcano in Yellowstone decades ago, and

Scientists estimate that a Yellowstone supervolcano eruption will result in the immediate deaths of 87,000 people. This figure includes people attending the park as well as people who live in the immediate area. The ash ploom will shoot high into the stratosphere, over 30 miles above the earth. The ash will cover much of the globe and block the sun’s rays, resulting in a “volcanic winter.” For example, temperatures lowered by an estimated 1F after the eruption of Mt. Pinotubo in 1991. Intense concentrations of the ash will remain in the stratosphere for about a month. The ash will fall to the ground as it cools resulting in the lands downwind receiving as much as ten feet of ash. The areas downwind from Yellowstone National Park include rich farmland and major cities. This inundation of ash will make the land …show more content…
The first problem would be the destruction of roads, runways, and farmlands from the falling ash. The roads would be impassable due to the heavy deposits of ash. At times the ash would create impassable roadways due to the depth of the ash, sometimes the ash would create slippery and treacherous conditions. Air travel will be no different. Runways would be unusable, and the ash suspended in the air will clog and destroy aircraft engines. Farmlands will fare no better. Even one centimeter of ash fall will result in destroyed crops and infertile soil. Moreover, communication could be crippled. Internet, phone lines, and cell phone communication will be disrupted due to the eruption and ash fall. This disruption of communication will hamper and restrict rescue and recovery efforts. It is suggested that the only means of escape would be on a boat through ash covered
In March 18, 1880 Mount St. Helens there was a catastrophic eruption that caused a huge volume of ash; the ash plume would be over central Colorado within 16 hours. After years of dedicated monitoring (knowing where to volcano is, unlike an earthquake not knowing exactly where this geological even is exactly) there was been increasing accuracy in forecasting eruptions.
What is a super volcano, what is a volcano? A volcano itself is a hill or mountain with vents to the crusts of the earth that let magma sit under or in the mountain. “A super volcano is any volcano capable of producing a volcanic eruption with an ejecta volume greater than 1,000 km3 (240 cu mi). This is thousands of times larger than normal volcanic eruptions. Super volcanos are on a much bigger scale than other volcanoes. Unlike composite volcanoes, with their steep sides, they are difficult to spot.” (Internet Geography, geography.learnontheinternet.co.uk) An average volcano in the world would just cause local damage, but this super volcano could end life on earth. Not just with the eruption but the ash would cause a volcanic winter blocking the sun to long and then even more the ash would choke everything out and collapse roofs. Yea Rainier would kill thousands of people, but Yellowstone would literally kill billions plus of people. In comparison, Rainier is a little fly and Yellowstone is a Griffin {The big eagle lion bird thing}. Yellowstone has the capability to erupt 1,000 times stronger than Rainier ever could.
Yellowstone National Park lies mostly in Wyoming, but three of the park’s entrances are located in southern Montana. People go to Yellowstone National park to see the view and the glaciers, some people go there to just go on a vacation to see the wildlife (Av2 books).
On May 22, 1915, an explosive eruption at Lassen Peak devastated nearby areas and rained volcanic ash farther 200 miles to the east! This explosion was the most powerful in a series of eruptions from 1914 through 1917. ...
The first time I saw Mt. Rainier for myself, was last summer when my boyfriend and I drove to Washington. It was the most beautiful, peaceful looking mountain I have ever seen. However, underneath it's great beauty, it hides a deadly secret. Mt. Rainier is one of the most dangerous volcanoes that we have here in the United States. One of the reasons it is so dangerous is because of it's great beauty. People enjoy looking at it, and the area that surrounds it, so they have made their homes here. Mt Rainier is not the only volcano I am interested in, in fact this last summer I also went to Mt. St. Helens and Crater Lake. But it is the volcano I chose to research for this paper because it does have so much beauty and at the same time so much power. I already know the basics about volcanoes, how they form, the different types, etc., but I wanted to find out more about what would happen if this great volcano were to erupt, what type of eruption would it be, and how would it affect the people that live around it.

The devastation caused by the Mt. Saint Helens eruption has been slowly repairing itself naturally. This recent eruption
Many of us know Mount Shasta to be a beautiful mountain and a popular tourist location in California. However, this mountain is much more than that, this mountain is actually a volcano. Volcanoes come with a number of hazards and a volcano of this size is of no exception. Previous eruptions on Mount Shasta have given us an idea of the power this volcano has and the damage it may do. With this information scientists are able to predict what may happen should another explosion occur.
Boom! A once ice-capped mountain peak explodes as ash fills the air. “‘Vancouver, Vancouver, this is it!’”Those were the last words of expert geologist David Johnston (Gunn 561). In 1980, Mount Saint Helens of the state of Washington erupted, filling the air with ash and causing mudflows powerful enough to lift tons. It decimated everything in its path. The eruptions, mudflows, and ash caused great damage on the landscape, yet it gave us information on how catastrophes happen and how they affect society and the surrounding landscape. The data acquired can also help us understand the way the landscape was formed. Mount Saint Helens caused much damage, but also helped people understand the science behind it.
Yellowstone is bigger than Rhode Island and Delaware combined. There are 50 mammal species, 311 bird species, and five endangered species. Rivers and lakes make up only 5% of Yellowstone (By 1870, Gold Fever Was Gone and the Great Yellowstone Expeditions Began. "Yellowstone National Park History."). The largest lake is called the Yellowstone Lake and is 136 miles long. The lake is known for having the highest altitude in North America ("56 Interesting Facts About . . . Var Addthis_config = ). In addition to lakes and rivers, there are about 290 waterfalls in the park. The highest waterfall is called Lower Falls and is 308 ft tall. Forests make up 80% of the park and an additional 15% is made up of grassland ("10 Surprising Facts About Yellowstone." National Geographic.). Yellowstone has one of the largest petrified forests from the big 1978 fire. The burned trees reformed into wood and minerals due to heat from the fire. The park sits on the Continental Divide, this means that half of the lakes run to the Pacific and the other half run into the Atlantic Ocean (United States. National Park Service. "Park Facts.). The average temperature during the summer is 70-80 degrees Fahrenheit and in the winter the average temperature is 0-20 degrees Fahrenheit. The average elevation is about 8,000 feet above sea level covered by mountains and lakes ( "Yellowstone National Park - Fast Facts."). The highest peak in the park is called Eagle Peak and is 11,358 feet high. The lowest peak in the park is Reese Creek which is 5,282 feet high. ( United States. National Park Service. "Park
Helens tallied up to be the most deadly and destructive eruption the United States had ever seen. “Approximately fifty-seven people were killed directly from the blast and 200 houses, 47 bridges, 15 miles (24 km) of railways and 185 miles (298 km) of highway were destroyed; two people were killed indirectly in accidents that resulted from poor visibility, and two more suffered fatal heart attacks from shoveling ash (Wikipedia 3)”. Just when it seemed the nightmare was over a second eruption occurred the following day. A quarter of the lava was fresh, and included ash, pumice, and volcanic bombs, and the rest was older molten rock. “The removal of the north side of the mountain (13% of the cone 's volume) reduced Mount St. Helens ' height by about 1,280 feet (390 m) and left a crater 1 to 2 miles (2 to 3 km) wide and 2,100 feet (640 m) deep with its north end open in a huge breach (Wikipedia 3)”. The downwind of the eruption also destroyed many agricultural crops such as wheat, apples, potatoes, and alfalfa. Overall Mount St. Helens was a major blow that cost the US 1.1 billion dollars, and struck fear into the hearts of all of America on May 18th,
Stories about volcanoes are captivating. Myths come in different versions, but all of them are capable of capturing yours, and everybody’s imagination.
Yellowstone National Park, a national park mostly located in Wyoming, on March 1, 1872 U.S. President You Lixi Simpson Grant Adams signed the bill passed by Congress after the establishment of the world's first national park. Yellowstone National Park, its abundant wildlife species and geothermal resources famous Old Faithful geyser is one of the most famous attractions. “Half of the world's geothermal features are in Yellowstone, fueled by this ongoing volcanism.”(Geothermal Features and How They Work. National Park Service, February 17, 2007 retrieved). Especially Old Faithful Geyser, one of the most famous landscapes in the park. It also has many types of ecosystems.
Volcanoes are one of the most destructive forces on Earth. It is estimated that some 500 million people live near active volcanoes (Lutgens and Tarbuck, 2013). Of the Earth's known volcanoes, 70 are expected to erupt each year with at least one large eruption each decade (Lutgens & Tarbuck, 2013). As populations continue to increase and more people are attracted to the beauty surrounding these areas, the immediate threat to humans from these sometimes sleeping giants grows. Due to this, the study of volcanoes and the service that volcanologists provide to the public by way of information and predictions on activity is immeasurable.
Yellowstone National Park is one of the largest national parks. Yellowstone has been a pioneer park for research in preserving wildlands for public use. Yellowstone National Park is located in the U.S. states of Wyoming, Montana and Idaho. It has many types of ecosystems and attractions.
