Mount St Helen Research Paper

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

A volcano is an earth hazard that occurs on faults between tectonic plates on a destructive boundary and an eruption is a natural disaster. A primary impact happens immediately after the disaster and before any response like death or collapsing or destruction of buildings. A secondary impact occurs later after the disaster, such less farm produce or a reduction in tourism. The severity of these impacts will differ considerably in a MEDC and LEDC where volcanic eruptions have taken place. These may be seen in the Mount St. Helen volcano eruption as well as in the Iceland volcanic eruption. They may also

In the early 1900s St.Pierre on the French Caribbean island of Martinique was famous tourist destination.”It was known as the Paris of the west Indies”, and home to more than 20,000 people,Mount Pelee sits about 4 miles from St Pierre.On May 8, 1902 the volcano erupted.

Imagine a single event that can kill 57 people and 7000 deer and elk. Snap trees like a toothpick, and turn the sky grey for 15 days. Now, stop imagining, Mount St. Helens, in the Cascade Range of southwestern Washington State, erupted. On May 18th,1980. According to (Campbell 371), “At least $1 billion in economic damage was reported”. The eruption of Mount St. Helens took many lives, and devastated America. Mount St. Helens destroyed more than 230 square miles of ancient forest.

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.

Helensvale is located on the northern end of the Gold Coast, approximately 65km south of Brisbane. It is a nice, tranquil suburb named after a local plantation owner, Ernest White’s sister, Helena. It was around 1870 when a plantation was formed in the area by Ernest White and Arthur Robinson. And in the 1980s, it welcomed its first residents with a shopping center and secondary state schools, sports centers, and parks, making Helensvale the first integrated suburb in the backcountry border of the Gold Coast.

The first recorded person in history to ascend Mt Druitt, an area in the relegated public squalor of Western Sydney, has also successfully reached the summit.

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

The blast was preceded by two months of intense activity that included over 10,000 earthquakes, hundreds of small phreatic (steam blasts) , explosions and the north side bulge. A magnitude 5.1 earthquake below the volcano at 8:32 am started the eruption. MSH is still a potentially dangerous and active volcano even though it has been quiet since 1995. In the last 515 years there have been four major eruptions and dozens of lesser eruptions. Two of the eruptions were only two years apart. In 1480, the eruption was about five times larger than the one in May 1980. There have been even larger eruptions during MSH' 50,000 year lifetime. After the May 18, 1980 eruption, there have been five smaller explosive eruptions over a five month period. Since then, there have been 16 dome building eruptions through October 1986 when the new dome in the crater was formed. As the mountain was torn open, the pressure in inside was suddenly relieved. The rock shattered inside the mountain was exploded out the top at speeds over 200 miles per hour. The blast was so strong that it leveled whole forest of fir trees. Geologist call this a "stone wind" since the winds carried the rocks form the blast with them. The rocks gave the winds extra force that let them flatten the trees. 150 square miles of land was leveled. The edges of this area also lost their forested areas from the heat of the blast and the fires it caused. The original blast of the

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).

The 1980 Mt. St. Helens explosion revolutionized the scientific study and volcanic monitoring; the devastation brought many geologists to investigate the scientific and hazard assessments of the massive volcano explosion. This explosion became the deadliest catastrophic volcanic event that killed many people and destroyed many communities, which the explosion created a major landslide, directed blast, eruption plume, pyroclastic flows, and lahars (Vallance, Gardner, Scott, Iverson, Pierson, 2010). Vallance, Gardner, Scott, Iverson, and Pierson (2010) point out that the 2.8- cubic- kilometer landslide reduced the summit and the sudden decompression of shallow gaseous magma caused a directed blast that traveled about 500 kilometers per hour

During the 1980 Mount St. Helens eruption, in which 57 people died, the total volume of the ash produced equaled an area as wide and long as a football field and about 150 miles high.

Mount Tambora is known as one of the most dangerous volcanoes in history. It is recognized to have one of the most hazardous eruptions, the 1816 eruption, with the death toll of 72,000 and more people.

With many evacuating and being evacuated by officials, some were stubborn and either stayed of traveled to witness. Time passed relatively peacefully for a while until about May of that year. On May 18th at 8:32am, in true stratovolcano characteristic fashion, Mt. Saint Helens erupted with a violent and intense explosion. The plume created stretched approximately 22.5km into the sky, blanketing most of eastern Washington in smoke and ash causing the skies to become pitch black by noon. The blast was approximately 100 times greater than ever seen before and the blast was so great that Northwest face of the mountain was essentially removed. The explosion caused a massive landslide and decreased the height of the peak of the mountain by approximately 396 meters (Mount St. Helens Eruption: Facts & Information,
