Yellowtone 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

A hazard is a situation that poses a level of threat tolife, health, property or environment. The level of hazard posed by different volcanoes can very greatly, from a weak eruption with minimal impact that causes little damage, to a voilent and life threatening explosion. Most of the sixty-plus volcanoes that erupt each year are low risk, however a combination of factors can cause a volcano to be a serious hazard. The factors causing these variations will be explained in this essay.

The volcanoes are located where there is a divergence or convergence in the tectonic plates and bring their lava from the deepest of the terrestrial mantle. The materials and explosions of these ginates represent a constant risk in the places inhabited by the human being, nevertheless the people ususually live in these areas no matter the risk. On the other hand the volcanos can change the geology of an impressive form, or to cool the temperature of the earth, or to darken the sky. The scientific community increases its efforts to try to understand better what happens in volcanoes, however it is impossible to predict these conditions.

The west coast of North America has been tectonically and volcanically active for billions of years. The Sierra Nevada Mountains in eastern California were born of volcanoes, and magma has been erupting in the Long Valley to the east of the mountains for over three million years (Bailey, et. al., 1989). However, the climactic eruption of the region occurred relatively recently in the region's geologic history. About 760,000 years ago, a huge explosion of magma warped the Eastern Sierra into the landscape that exists today. The eruption depleted a massive magma chamber below the earth's surface so that the ceiling of the chamber imploded, forming what is now known as

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

The Geyser Old Faithful in Yellowstone National Park, U.S.A. is a geyser that has a relatively isolated source of seismic noise. The seismic behavior of this one geyser is similar to many volcanoes observed.

Lava from this powerful volcano can cover an area twice the size of Washington D.C. The lava can cause a large amount of wildfires that could ruin the habitats of many wild animals, and decimate the population of animals, and trees. “During eruption, these flows oozed slowly over the surface, moving at most a few hundred feet per day for several months to several years, destroying everything in their paths”(volcanoes.usgs.gov). This can be a total devastating event and can change what we know as Yellowstone today. Last but not least this volcano can alter the

The last major event for the Yellowstone volcano's was nearly 630,000 years ago, and we are still learning more and more about the seismic system every day. Previously, we believe that the last “super eruption” was one blast that resulted in a mass covering of ash in the atmosphere. This resulted in a blockage of sunlight from hitting the earth causing an ice-age. However, a study on the layers of ash in the water surrounding the Yellowstone national park have shown that the most recent eruption was actually 2 eruptions 170 years apart. The ash at the bottom of rivers and lakes in California are an amazing tool in determining historic temperatures. The most recent analysis on this ash has shown that after the first event there was a major drop

Yellowstone is one of the largest known volcanoes in the world and the largest volcanic system in North America. The volcano is found above an intra-plate hot spot that has been feeding the magma chamber for at least 2 million years. The giant caldera is the product of a large-scale collapse of the crust after 3 ultra-plinain or super volcano eruptions, large explosive events that erupt several hundreds to few thousands of cubic km of magma. These eruptions took place 2.1, 1.3 and 0.64 million years ago. Yellowstone’s magma chamber is believed to still be active and contain at least 15,000 cubic km of melt. Yellowstone volcano is located in Yellowstone National Park, Wyoming, United States. Yellowstone volcano is a super volcano; last time

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.

In these eruptions, instead of the mixture of gas and ash flowing upwards, it flows outwards and hugs the ground. These eruptions are extremely dangerous.

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

During a magmatic episode, a high discharge rate of magma is likely to produce lava fountaining high into the air. It is inferred that the higher the fountaining, the more exposure the lava has to cool air, thus increasing its viscosity. Further, with a high flow rate, lava continues to move even if viscosity and yield stress is high. This continues up to a point at which surface disruptions can no longer be “healed”, and the transition threshold is duly reached.

When asked the questions of how volcanoes look and work, we give an answer based off of our general knowledge. Yet some research into the functions of volcanoes and different types there are prove they are much more than just lava flowing geological cones. I will be going into focus about the different types of volcanoes and how to tell the differences between active, inactive, and dormant volcanoes. My focus of approach is merely into the research of volcanoes from past to present.

Sparks explains how not only can rising magma cause the earth the bulge, but it can also trigger earthquakes. Magma can trigger earthquakes because as it moves towards the surface of the earth, rocks will move and cause stress on surrounding rock material. These earthquakes are relatively small and last for a long period, which distinguishes them from other seismic activity. The earthquakes are slow because they resemble the fluid movement of the magma beneath the crust. These small scale earthquakes will continue to occur up until an eruption. The changes in intensity of the earthquake mimic the weakening of the crust. Often times this method is paired with the previous method of watching for the crust bulging to indicate volcanic activity. But also like the previous method, seismic measurements can be faulty when predicting a volcano. Sometimes seismic activity will only relate to tectonic movement and not an eruption. The measurements of seismic activity can also provide an estimate of what kind of flow a volcano will produce and at what speed it will travel. The seismic method of predicting a volcanic eruption was effective in the case of Mount Redoubt in 1989 and 1890. There were 11 spells of seismic activity before the eruption and people were able to evacuate in time. The seismology method of predicting an eruption is effective within days or minutes of an eruption (Sparks,
