Mount St. Helens Research Paper

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

Mount Saint Helens, located in the Cascade Volcanic Arc, is known to be one of the most deadliest and disruptive volcanic eruptions in recent history. It has a height of roughly 8,300 feet and is a stratovolcano. A stratovolcano is essentially a steep sided peak volcano that is very high in viscosity and contains large traces of volatiles, and additionally are large in nature. (Abbott). On May 18th, 1980, a 5.0 earthquake triggered a massive landslide which basically caused a side of the northern flank to fall down the summit. The blast destroyed nearly 230 miles of land and is claimed to

Have you ever been near a volcano when it erupted? Most of us haven't, but if you're unlucky enough, you just might have. Many people think it would be cool, but it is indeed not. In fact, the people of Pompeii were very unlucky when Mount Vesuvius erupted in 79 AD. Nearly two-thousand people died. Although that eruption was very similar to the 1980 eruption of Saint Helens, it was also very different.

The side of mt st Helens has been blown off by the force of the blast and trees have been demolished buy the rocks crashing at them

Normally, lava was able to flow out cracks or also known as vents in the mountain closing. But one day, Lava was building pressure on Mount St. Helens. At the end of April 1980, Mount St. Helens began to grow silently. Swelling was spotted on the

It was May 18th, 1980. The eruption of Mount St. Helens occurred in Washington,United States. The exact time it had happened is at 8:32:17. The eruption happened 96 miles out South of Seattle, Washington and 50 miles northeast of Portland,Oregon. Many people died during this time. About 50 people had died. 250 homes were destroyed. Along with 47 bridges, 15 miles of railways, 185 miles of highway was also destroyed. Many tiny earthquakes had happened a couple days before the eruption had happened.

Both countries environment took a huge blow. Effects on the Landscape due to Mt St Helens include 400 metres was blown off the top of the mountain and a one mile horse shoe-shaped crater was left that was 500m deep. Every plant and animal within 25km north of the volcano was killed – approximately 7000 animals died. Every tree within 30km of the volcano was flattened. The water produced from melting ice and snow on top of the volcano creates

It goes on to explain some of the Europeans to first record the sighting of the mountain which happened May nineteenth seventeen ninety-two during the surveying of the northern Pacific Ocean. It was named by Vancouver for a British diplomat, "1st Baron St. Helens," on October twentieth seventeen ninety-two, but before this local Indians had already named it louwala-clough or smoky mountain. In eighteen twenty-nine Hall J. Kelley led a campaign and planned to rename this mountain and all others after one of the United States president, he had tried to rename Mt. St. Helen to Mount Washington. As horrible as the explosion in May og nineteen eighty claimed lives the paper says if the explosion had waited just one day later on Monday rather Sunday when all the people were at work such as loggers they believe the death poll would have been much more higher. A second eruption was noted to had occurred on may twenty-fifth, noone was thankfully hurt and a rather popular film was then created named The Eruption of Mount St. Helen. After all that occurred with the volcano and all it put everyone through president Ronald Reagan in nineteen eighty-two established the Mount St. Helens National Volcanic Monument, which still to this day remains a famous natural laboratory for the study of earth processes,nature, and catastrophes. The volcano and the area surrounding still have a long way to go before it recovers and has all the things it had

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

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.

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

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.

So, true it does show that disaster is impulsive no matter what we try to do. Also, the eruption of Mt. Helens did give many individuals data about what transpires before and during eruptions. The amazing part to me was the lump on the side of the volcano that was fulling up with lava. Additionally, these natural landmarks (volcanoes) are astonishing but we must be very cautious about them.

On May 18, 1980, 35 years prior to today, a quake struck underneath the north face of Mount St. Helens in Washington state, setting off the greatest avalanche in written history and a significant volcanic emission that dispersed powder over twelve states. The sudden horizontal impact, heard many miles away, removed 1,300 feet off the highest point of the volcano, sending shockwaves and pyroclastic streams over the encompassing scene, leveling backwoods, softening snow and ice, and creating monstrous mudflows. Fifty-seven individuals lost their lives in the tragedy (Grisham).

For some people, volcanoes are apart of their everyday life. Volcanoes may affect humans but they also affect other organisms. Depending on how big the eruption is, the magma from the volcanoes can spread and kill plant life and animals. “Mount St. Helens provides an example. The Washington Department of Game estimated that 11,000 hares, 6,000 deer, 5,200 elk, 1,400 coyotes, 300 bobcats,
