Mt. Rainer Plate Boundary

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

Let’s begin with Mount St. Helens which is located in the pacific northwest of the United States. To be more specific it is located in Washington State and is a part of the Cascade mountain range that spans from California to Canada. It is a composite volcano, which has steep sides that are formed by alternating layers of lava

I: The objective of this lab was to understand how plate boundaries work. We were to find the major plates and compare and contrast them.

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.

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

I decided for my project that I would spend the time researching Mount Baker. Mount Baker is located about 30 miles east of Bellingham, Washington. The Cascade Mountain range extends over 140 miles between Seattle, Washington and Vancouver, Canada. Mount Baker is a Stratovolcano, which is also known as a composite volcano, it is also the highest peak in the North Cascades and the fifth highest in the Cascade mountain range (Volcano Hazards Programs). Cities located near Mount Baker include Abbotsford, British Columbia and Bellingham, Washington. The closest stream to the mountain is the Nooksack River which runs near the west side of the mountain. On the southwest side of the mountain is Baker Lake. I chose this area because it is a very

Feel free to stretch, it's been a long ride. We will be stopping by a restaurant later to get some lunch. In front of you, you can see Humphreys Peak, the tallest mountain in the San Francisco Peaks. The San Francisco Peaks is actually a volcanic mountain range and is part of the San Francisco volcanic field. The peaks were once a stratovolcano but is now eroded and are the remains of the volcano. It is the only stratovolcano in the San Francisco Volcanic Field. The tallest mountain, Humphreys Peak, is about twelve thousand, six hundred and thirty-three feet in elevation, which is also three thousand, eight hundred and fifty-one meters tall. In fact, Humphreys Peak is the tallest point in all of Arizona. Also in this area, are more than six hundred volcanoes. Most of the volcanoes found here are basalt cinder cones. These volcanoes are relatively small. They are also usually less than one thousand feet in elevation. Another fact about these basalt cinder cones is that they are formed within a range of a couple of months to a couple of years. The San Francisco Volcanic Field also has several lava domes. Lava domes are formed by dacite and rhyolite magmas. Both of those types of magma are very rich and high in silica. So, as a result, the dacite and rhyolite magmas are very viscous and thick. As a matter of fact, the magmas are so viscous is thick that when volcanoes erupt, the magma tends to pile up and form very steep sided masses, which are the domes.

To begin my search I went to my favorite search engine, Yahoo.com. I have always found that this engine is the easiest to use, and gives you the best information. At first, I researched all volcanoes, not just Mt. Rainier. There was so much information out there that I found it difficult to narrow it down to just 10 for my annotated bibliography. I was able to spend hours on the computer exploring the various sites and finding out new information. From most of the sites I went to I was able to link to other sites that had to do with the same subject. I found this to be very useful in doing my research. Not only did I find information about volcanoes and how they work, I found places where I could buy volcano merchandise, watch real time videos of eruptions, and look at volcano cams from around the world. I learned so much about all kinds of volcanoes from my research, but when it came down to answering the questions that I had asked, there were two web sites that I found were the most useful, The US Geological Societies Cascades Volcano Observatory, and Volcanoes Online. These two I found to be the most useful in my research.

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.

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

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

Grand Canyon is not near any plate boundary. It is the past plate boundary movements along with erosion that form this great canyon. The canyon is considered a plateau canyon because it has been uplifted and the large amounts of water that have created it. The converging plate boundaries of the Pacific Plate and the North American plate led to the forming of the Grand Canyon. These two plates collided and the oceanic crust was subducted. The subduction of the ocean crust forced the continental crust upward and the Colorado Plateau was formed by this upward push . The uplift of the Colorado Plateau allowed the Colorado River “to carve its way downward” and therefore creating the canyon.

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

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 cities of Weed, Mount Shasta City, McCloud, and Dunsmuir lie in the shadow of Mount Shasta and could be devastated by an eruption. They lie close enough to the base of the mountain that they could suffer damage from pyroclastic (hot gas, rock, and ash) and lava flows, tephra (rock fragments and particles ejected by a volcanic eruption)., lahars (destructive mudflow), and ballistic ejecta. Based on recent behavior, it is not likely that Mount Shasta will erupt catastrophic volumes soon. However, smaller eruptions are possible. At least ten eruptions have taken place in California in the past 1,000 years according to the USGS. Most recently, Lassen Peak in Lassen Volcanic National Park had a series of eruptions from 1914 to 1917. Concerned people and groups work with the government to hopefully solve or at least slow global warming which could be so disastrous to not only Mount Shasta but the entire planet Earth. Government funded studies had verified that the Mount Shasta area is the ancestral home of the Wintu tribe and the mountain is central to the Indian belief systems (Nabov). People must be aware of the delicate balance that can easily be disrupted and treat the area with respect and care to preserve the beauty for coming generations. Mount Shasta was designated a National Landmark in December of 1976.
