Mount St. Helens Eruption I have never experienced a volcano erupting before because there are no volcanos where I live. A volcano is a hole in the earth’s surface where gasses, magma, pieces of rocks, and ashes explode from the earth. Mt St. Helens eruption included many details common to other eruptions that caused damage and destruction to property and lives affected the region has recovered in its aftermath. The eruption of Mt St. Helens had a dramatic affect common to many other eruptions around the world. This disaster occurred in Washington on May 18, 1980. 57 people were killed including a geologist named Johnston who was studying the mountain. This eruption caused much damage and destructions. The mountain was about 9,677
In March 18, 1880 Mount St. Helens there was a catastrophic eruption that caused a huge volume of ash; the ash plume would be over central Colorado within 16 hours. After years of dedicated monitoring (knowing where to volcano is, unlike an earthquake not knowing exactly where this geological even is exactly) there was been increasing accuracy in forecasting eruptions.
To start, these names are the names of two big volcanos, both in Washington State, both deadly, but on different scales. Mt. Rainier’s last eruption was 150 years ago. Yellowstone’s last eruption was 640,000 years ago. Yellowstone’s reputation of being the ultimate super volcano versus Mt. Rainier, the most dangerous volcano in the country. The difference between these volcanos is looks, damage, stability and tourism.
Mount St. Helens is located in the Cascade mountain range in the southwestern region of Washington in the United States. It is known as the largest volcanic eruption to occur in North America on May 18th of 1980. Mount St. Helens is located on a destructive boundary where the convergent plate boundary, Juan De Fuca Plate, collided with the North American Plate (3). There are three different types
On May 22, 1915, an explosive eruption at Lassen Peak devastated nearby areas and rained volcanic ash farther 200 miles to the east! This explosion was the most powerful in a series of eruptions from 1914 through 1917. ...
...815 eruption of Mount Tambora. With over 70,000 deaths and a rating of 7 on the volcanic exclusivity index, this eruption is one of the largest in recorded history. Not only did this volcano cause destruction in Indonesia but the consequences were further felt around the world, as volcanic ash and sulphuric gases were dumped into the stratosphere causing a global climate shift. Dark clouds covered the sun, and dramatic weather changes ensued. Flash floods frequently occurred wiping out a great deal of crop eventually causing prices to skyrocket. Disease began to spread due to malnourishment and unsanitary living conditions. Eventually these consequences subsided and citizens began to migrate towards Mount Tambora once again. Today the government has placed seismic sensors are set up in the most volatile areas to ensure preparedness in the event of another volcano.
The first time I saw Mt. Rainier for myself, was last summer when my boyfriend and I drove to Washington. It was the most beautiful, peaceful looking mountain I have ever seen. However, underneath it's great beauty, it hides a deadly secret. Mt. Rainier is one of the most dangerous volcanoes that we have here in the United States. One of the reasons it is so dangerous is because of it's great beauty. People enjoy looking at it, and the area that surrounds it, so they have made their homes here. Mt Rainier is not the only volcano I am interested in, in fact this last summer I also went to Mt. St. Helens and Crater Lake. But it is the volcano I chose to research for this paper because it does have so much beauty and at the same time so much power. I already know the basics about volcanoes, how they form, the different types, etc., but I wanted to find out more about what would happen if this great volcano were to erupt, what type of eruption would it be, and how would it affect the people that live around it.
The eruption of Mt St Helens had a major effect on the surrounding natural community, especially on the fauna located in this area. Volcanic matter blasted by the eruption caused 6 million trees to become uprooted and/or flattened. [i] Due to Mt St Helens spewing sideways unlike normal volcanic eruptions many species were eliminated around the blast zone.[ii] In less than 10 minutes the blast had flattened over 500 square km of forest.[iii] Species such as mosses, ferns, shrubs and wildflowers dissipated.[iv] The eruption caused all living organisms to die in the upper North Fork Toutle River as well as destroying 2km of the river itself.[v] According to the Washington State Department of Game more than 12 million animals had died.[vi] These
Fifty-nine people dead, 200 homes destroyed or damaged. What could cause so much damage? Many things but in this case Mt St Helens, a volcano that erupted and caused the death of innocent humans and the damage of their homes. It wasn’t like a normal volcano that flowed lava, the whole top flew off. Hundreds of square feet were completely ruined, huge plots of land with nothing but garbage.
The eruption on Mount Saint Helens has a specific cause and comes with many effects. A multifold of people would say that the “mountain looked like the site of an atomic blast” (Bredeson 30). That is a very accurate depiction as it took great power to inflict as much damage as it did. The reason for this impressive amount of force is that when magma is built up with pressure and an earthquake hits, the pressure gets magnified and the volcano explodes (Lewis). This is exactly what happened inside Mount Saint Helens. Furthermore, it has been revealed that “The earthquake that triggered the explosion was a 5.2 on the Richter scale” (Gunn 559). The earthquake to the magma can be compared as a match to gasoline. Even though the earthquake was not huge, the scale of the eruption was much greater than that of the earthquake (Gunn 560). The earthquake was only the trigger that allowed for more devastating things to occur. Thirteen hundred feet of the volcano were lost in the explosion followed by landslides, mudslides, and lava flows...
Deep within the Washington wilderness in the shadows of Mount St. Helen lies the infamous Ape Canyon. Upon these steep shallow cliffs, strange encounters have emerged over the past century. In 1924 a group of seasoned miners set out on a routine expedition searching for gold. However, what they encountered changed their lives forever. It was here that allegedly famous attack by a group of sasquatches occurred. In the short autobiography, I Fought the Apemen of Mt. St. Helens by Fred Beck, one of the miners, recollects his parties encounter with the beast.
Mount St. Helens is an active stratovalcano in Skamania County, Washington, in the Pacific Northwest region of the United States. It is located 96 miles south of Seattle and 53 miles northeast of Portland, Oregon. The mountain is part of the Cascade Range. It is most famous for a catastrophic eruption on May 18, 1980. That eruption was the most deadly and economically destructive volcanic eruption in the history of the United States. 57 people were killed, and 200 homes, 47 bridges, 15 miles (24 km) of railways and 185 miles (300 km) of highway were destroyed. The eruption blew the top of the mountain off, reducing its summit from 9,677 feet to 8,364 feet in elevation and replacing it with a mile-wide horeshoeshaped crater.
These differences are in the makeup of the volcano, the impact on society, and the eruption itself. Mount Saint Helens, used to be a wonder of the world, but now a damage site of what happened on May 18, 1980. Mauna Loa is a tourist destination and one of the most active dispensers of lava and magma in the world. As shown, these volcanoes can’t be more different. Yet, each volcano has been a culprit to destruction, and have similarities within themselves. This report has expressed many similarities and differences and brought facts and knowledge to the historical eruptions by these impressive and ancient structures of
Stories about volcanoes are captivating. Myths come in different versions, but all of them are capable of capturing yours, and everybody’s imagination.
