Yellowstone National Park Essay

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

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

The cataclysmic eruption which caused the collapse of the caldera and the deposition of the Bishop Tuff was an explosive, fast event. It ejected coarsely porphyritic biotite rhyolitic ash and viscous lava with an approximate silica content of 76 percent. The total ejecta came to about 600

One summer my parents informed my brother Ben and I we were going on a trip to Yellowstone National Park. I had never been so excited for anything in my life. I had a passion and love for nature, and being that Yellowstone had some of the most beautiful and interesting geological features on Earth, I knew I would have a blast. They said we would be going in a few weeks, and I literally couldn’t wait. I kept asking questions upon questions, and finally, my dad just got annoyed. “Go research it, Juliette.” He said. “The internet will know more than I do.” I took his advice and went to research Yellowstone.

Lava flows of rhyolite and basalt have flowed through parts of Yellowstone as recently as 70,000 years ago. These lava flows destroyed everything in their paths while moving slowly at a rate of a few hundred feet per day, flowing months, or sometimes even several years. They are thick and cover as much as 130 square miles. They have nearly filled the Yellowstone Caldera, and spilled beyond the caldera’s border. These lava flows are responsible for forming four of the nine named plateaus in

Lake Toba is located in Sumatra, Indonesia (Figure 1). The Toba Eruption was the last of three major eruptions, which occurred over the past million years, creating a volcanic caldera1. The most recent eruption, also known as the Youngest Toba Tuff erupted around 73,000 (± 4000) years ago2. This created a global catastrophe that effected many species, including humans. Many researchers have linked this even to the most recent bottleneck in human evolution resulting in a dramatic drop in the human population to only about 3,000 to 10,000 in a very short period of time3.

Volcanic eruptions are very problematic to predict despite how much technology has advanced over the generations in terms of magnitude and the impacts that it has had on people throughout history. An eruption is defined as “The ejection of molten rock, steam, etc., as from a volcano or geyser” (Dictionary.com, 2016). There are many reasons as to why volcanic eruptions are so difficult to predict and there are many examples of volcanoes down the ages that have impacted humans tremendously and posed potential risks to people when prediction was not able to influence an evacuation or contribute to saving lives. The size of the eruption is a factor that; when not predicted can intensify the impacts of an eruption enormously and result in a disaster.

At 3:39 PM on June 15th, 1991, Mt. Pinatubo had it’s largest and most destructive explosion lasting a total time of 10 hours and 34 min. The ash from the plinian eruption soared 35 km  into the air covering a grand 40 km radius. Avalanches of pyroclastic debris raced down the side of Pinatubo, filling valleys with brand-new volcanic deposits as much 660 feet thick. A small caldera 1.6 miles across formed because the eruption removed so much magma and rock which caused the summit to collapse. Surrounding forests were buried by 50-200 meters of ash and pumice. Ash deposits of 5 cm sheeted an area of 4000 mi².

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

The U.S. Geographical Survey (USGS) uncovered that there is a humongous magma supply underneath the Yellowstone National Park in Idaho. The aftereffect of this magma reservoir is not only a normal fountain of liquid magma, but rather a supervolcano, which is eleven times more grounded.

The stratovolcano Tambora makes up the 60-km wide Sanggar Peninsula on northern Sumbawa Island, Indonesia, and is still currently active today. Erupting on April 10, 1815, Tambora, which is considered the largest observed eruption in recorded history, induced mass destruction to villages, widespread famine, and global climate change that would last for years to come. Standing nearly 14,000 feet high, Tambora experienced small tremors and streams of pyroclastic flow before erupting, shooting 60 megatons of sulfur, 36 cubic miles of ash, pumice, and aerosols into the atmosphere. Sulfurous gas from the volcano combined with water vapor droplets in the air, which then stuck in earth’s atmosphere, and were dispersed through both hemispheres due to stratospheric currents. These particles then increased sunlight absorption, contributing to lower amounts of sunlight seen from earth. This caused a drop in global temperatures by nearly 5.4 degrees fahrenheit. These temperature drops reached as far as New England, which caused difficulty in crop production and increased famine, leading to the year of 1816 being called the “year without a summer.” The initial impact of the eruption killed somewhere around 10,000 citizens instantly, while the chain of events afterwards, including food shortages, famine, pyroclastic flows, and tsunamis, caused an estimated 100,000 deaths.

The Yellowstone Caldera is a volcanic caldera and super volcano. The volcanism at Yellowstone deal with the Caldera, it was created during an eruption, these events took place in 2.1 million, 1.3 million and 630100 year ago. The caldera is a volcanic depression. It occurs, when the magma is reserve, the magma emptied the caved, it usually form in a round shape. The Yellowstone Caldera is about 35 mile wide and 50 mile long. However, in some study, they say the Yellowstone Caldera is large than previously thought. The Caldera is on top of a hotspot, the hotspot is where the light , and hot molten rock are find at, with those item it cause the mantle to rises toward the surface. The Yellowstone Caldera was created after an explosion of magma,

One of the most devastating weather extremes happened 250 million years ago. A massive volcanic eruption (that occurred in an area now known as Siberia) caused increase in carbon dioxide and methane levels resulting in the extreme global warming. Today, the remains of this volcanic activity are called Siberian traps. The origin of Siberian traps is considered to be a mantle plume that burst through Earth’s crust releasing large volumes of basalt lava. Radiometric dating showed this volcanic event took place approximately from 251 to 250 million years ago (Reichow et al., 2009). Siberian traps erupted over several vents releasing around 2.5 million km3 of basalt lava that covered up to 60% of Siberian craton (Fedorenko et al.,

In this report I plan to discuss the geological event of volcanic eruptions and the disasters they cause. To me, this is a fascinating topic and timely seeing how the 19th anniversary of the eruption of Mt. St. Helens is upon us. I hope to inform people of the mass destruction that is caused by the eruption of a volcano. The scope of my report will be limited to: 1) describing what comes out of a volcano, 2) explaining the seven different types of volcanoes, 3) explaining the five types of volcanic eruptions, and 4) explaining the disasters they can cause people. The procedure for completing this report first started by watching educational television

We continued to walk on the walkway while looking out the little island and the large sphere that was placed in the middle of it. This magical ball reflected the scenery of the earth. I could see the trees, the white storks, and the darkened sky in its reflection. And there we were within it, a number ten looking captivatingly at the parallel world on its surface. After a long gaze at the spellbinding sphere, we ventured up the island to find a place to sit down and rest for a while. There was an isolated dark metallic bench sitting at the very far end of the park. We both sat down and said nothing. I stared at the grand view of the park. Everything was intact and flawlessly organized. The sight made me appreciate nature more, and I laughed inside my head about many couples who want to spend their day in a luxurious restaurant eating expensive foods or shopping around in crowded spaces. For a “proper” date, many people would expect to see roses, rings, sex, kisses, and a lot of touching. For us, it was the serene silence that brought us closer. The more I think about this event, the more I relate to the idea that we attempted to be “normal” instead of being “cheesy.”
