Ferguson Volcanoe Research Paper

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

A period of volcanism resulted in igneous intrusions within the Raton Basin-Sierra Grande Uplift Province that was sourced from the upper mantle about 26. 6 billion years ago and is associated with parallel dikes and sills (Higley, 2007). Igneous rocks are common within the Raton Basin and include Tertiary dikes and sills that range in age from 6.7 to 29 5 million years ago (Flores and Bader, 1999). One of the main differences between dikes and sills is that dikes are longer lived magma conduits and sills are features that form when magma is in neutral buoyancy with the surrounding rock (Rooper et al., 2006). These volcanic events are associated with hydrothermal alteration of coal within the basin (Higley, 2007).

Mount St Helens erupted on the 18th May 1980 at 9am and is an active strata volcano Washington State USA, a MEDC. Where as on 18th July 1995, during the daytime, Montserrat, a LEDC during the day, Montserrat's Soufrière Hills composite volcano of a height 1050m, meaning sulphur hills, dormant for centuries, erupted and produced a phreatic eruption. The volcano is a strata volcano also. Mount St. Helens is a composite volcano which lies near to a destructive plate boundary where the small Juan de Fuca Plate is being subducted underneath the North American Plate where as the eruption

Washington has five major volcanoes as a part of the Cascade Range. Ten volcanoes line the state of Washington as a small portion of the ring of fire. Washington’s weather can also change rapidly at anytime and anywhere unexpectedly.

Mt St Helens (or the Fuji-san of America) is known for the May 18th, 1980 eruption which destroyed the whole north side of the volcano in just a few minutes within a 6 mile radius. Mount St Helens is named by George Vancouver after a British Diplomat nicknamed Baron St Helens. Mt St Helens is located in Yakima, Washington State, United States, North America on the North American tectonic plate. (Which is a continental plate) Yakima, Washington is almost right in the middle of the state, but Washington borders British Columbia and Alberta, Canada and Idaho and Oregon, United States, and of course, the Pacific Ocean.

The first sign of Mt. St. Helen exploding was a landslide starting at the rim of the summit crater. In 15 seconds, the north side of Mt. St. Helen was making its way down the side of the volcano. After the entire north side had collapsed superheated gasses and lava were released in a massive lateral explosion. This abrupt release of pressure created a nuees arfentes, “which is (in a volcanic eruption) a swiftly flowing, dense cloud of hot gases, ashes, and lava fragments.”1. The nuees arfentes wiped everything within 8 miles almost instantly. The shockwave rolled over the forest for 19 more miles forcing almost all of the centuries old trees to fall towards the north. After those 27 miles the trees remained upright but were burnt to death.

Mount St. Helens Location: Washington, United States Latitude: 46.20 N Longitude: 122.18 W height: 2,549 meters or 8,364 feet - 9,677 feet before May 18, 1980 Type: Stratovolcano Number of eruptions in past 200 years: 2-3 Latest Eruptions: Between 1660-1700, around 1800-1802, 1831, 1835, 1842-1844, 1847-1854, 1857, 1980-? Present thermal activity: strong steaming Nickname: Mount Fuji of the West Remarks: continuous intermittent activity since 1980 with occasional eruptions of steam and ash; occasional pyroclastic flows; intermittent dome forming. MSH is considered a young volcano that developed over the last 40,000 years and is one of the most active volcanoes in the Cascade Range. Geologists predicted that the

It is minimal realized that lying underneath one of The United States biggest and most beautiful National Parks - Yellowstone Park - is one of the biggest "super volcanoes" on the planet. Every year, a huge number of guests come to respect the hot springs and fountains of Yellowstone, the Nation's first national park. Few are mindful that these miracles are powered by hotness from a vast repository of incompletely liquid rock (magma), simply a couple of miles underneath their feet. As this magma-which drives one of the world's biggest volcanic frameworks climbs, it pushes up the Earth's hull underneath the Yellowstone Plateau.

Mt. Saint Helens is a volcano located in Skamania County in Washington. It is the product of when tectonic plates on the surface of the Earth collide. Like how most volcanoes are formed, the formation of Mt. Saint Helens began with subduction of the Mt. Saint Helen Juan De Fuca plate underneath the North American plate. An explanation of why this happens is because the water weight on top of the oceanic plates increases the density of the oceanic crust in which eventually, it slides under the continental crust. The oceanic plate (Mt. Saint Helen Juan De Fuca plate) then goes farther underneath the continental plate and the lithosphere. It eventually reaches the asthenosphere part of the upper mantle where the plates are melted and turn into

Mount St. Helen is a very active volcano classified as a stratovolcano, stratovolcano is basically a tall volcano built up of layer after layer of hard lava, tephra, pumice, and volcanic ash. Mount St. Helens location is in Skamania County in Washington, with coordinates of 46 12'00.17"N122 11'21.13"W. Mount St Helen is famous because of its catastrophic eruption on May eighteenth in nineteen eighty. The eruption measured a five on the volcanic explosivity index. This is an index created by Chris Newell and Steven Self in the year nineteen eighty-two it was designed to try and measure the explosiveness of volcano eruptions to determine the value of the explosivity and qualitative observations ranging from zero to eight, eight being the

Simultaneously, Mt Adams is the second highest mountain and the most under looked volcano in Washington State. In terms of volume, Mt. Adams is the second largest volcano (behind Mt. Shasta) in the Cascade Range (Alt & Hyndman 1984). Since it has been relatively quiet for the past couple millennia, it does not receive as much attention as it’s counterparts and draws very few tourists due to it’s remote setting (Hill 2004). Prior to recent research, not much was known regarding Mt. Adam’s eruptive history, frequency or how explosive previous eruptions have been. (Hildreth & Lanphere 1994). In this paper, I will discuss the geography, history, geology, and hazards of Mt. Adams and it’s surrounding area; focusing heavily on its geology and geologic hazards.

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

agriculture and it many casualties and devastation resulted from Mt. St. Helen’s eruption. The Skamania County, Washington, and even though it was very tricky with many things lost and live too, but everyone from May 18, 1980 to now will still remember this day if they are still alive. If you ask some about this great eruption they person may know a thing or

Volcanoes can be found throughout the entire world and are formed when there is a rupture in the mantle of the Earth's crust. This effect allows the output of volcanic lava, ash, and various types of gases. These tectonic plate breaks are normal, the planet Earth is divided into 17 tectonic plates and consistently move against each other forming shifts from low to high intensity. It can cause displacement of earth or water.

The play Prince of Egypt directed by Scott Schwartz an American child actor who participated in Toy Story and now a director has shown his vision of the marvelous play in the Silicon Valley TheatreWorks. Additionally, the play itself is dramatic and musical. To sum the play, an orphan Hebrew was found near the river and was brought into one of the most prestigious family in Egypt. A huge amount of time has passed seeing Moses (Hebrew child) and Ramses (Son of the Pharaoh) growing up together into adults. However, a war caused the sickness or death of the Pharaoh, which leads Ramses to be the new leader. Moses and Ramses has a strong bond between each other, until Moses finds out his true identity; which is being born as a Hebrew. Eventually finding out his true self, his goals were to free the Hebrews being captive by the Pharaoh, which in this case it is now Ramses. With hard work and determination, Moses has fulfilled his duty to free his people. In the ending of the play, I was amazed and enjoyed the play. Therefore, I wished for another seeing of this beautiful work just by how the themes, plot, creative staging, and the passion of the director is put out there to everyone else.
