Mount St Helens Research Paper

With no prolonged periods of inactivity the volcano has continuously built up on itself. The last major eruption took place in 1790 and killed many people and animals, but numbers are unknown4. Starting in 1983 there was a chain of several eruptions that started and have yet to stop pushing lava through a lava tube till it reaches the Pacific Ocean. Over a span of twenty year the flow has

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.

Kilauea is a volcano in the Hawaiian Islands it is one of the five shield volcanoes in the Hawaiian language Kilauea means spewing or spreading. Mt St. Helens is an active stratovolcano in Washington it is named after British diplomat lord st Helens.

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.

According to The International Trade Commission “estimated damages to timber, civil works and agriculture to be $1.1 billion. In addition, Congress approved $950 million in emergency funds to the Army Corps of Engineers, FEMA, and the Small Business Administration to help recovery efforts.” What if Mount St. Helens would not of exploded? What if Fifty-seven people would still have a chance to live life? People would still have a chance to see the crystal clear Spirit lake and the ancient forests of Washington. Families would not haft moan about loved

11. The Kilauea Volcano eruption was one of the largest and the most destructive for its time, “As the lava field spread, cooled and spread again over the next three years it destroyed many homes and the Visitor Center…” (http://www.livescience.com/27622-kilauea.html) Familys and companys had no were to go, jusst like the the people in the Dust Bowl at the

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.

Enjoy the close view of Mount St. Helens. Once named Plymouth, St. Helens is located only about 39 miles away from Mount Saint Helens in Washington. The view of the mountain is responsible for the change in name and has inspired many who live close by. Take in the view as you walk to the Columbia County Historical Society Museum or Grace’s Rivertown antiques on a cool

Voted the second most beautiful vista in America, Mount Washington is a well-known overlook of downtown Pittsburgh. Mount Washington, now a beautiful mountain with a tree covered Cliffside, was not always known for its sights. Many are unaware of the dirty environment that it used to be. Once known as Coal Hill, Mount Washington was the location of many coal mines. Back in the late 1800’s, this mountain was the source that fueled and built Pittsburgh. From the ravaging coal minds to the breathtaking Inclines, there is a lot of history that is hidden under the beautiful area which we now know as Mount Washington.

Senator Peter Norbeck was Mount Rushmore's great political patron and promoter of the construction of the giant structure. Norbeck helped raise almost a million dollars for the project during the years of the Great Depression.

Consequently, it would have led to contamination of the water and the spread of disease. 230 square miles of forest burned and got destroyed. This would have a great effect on the logging industry because there would not be as many trees for them to cut down. In addition to this it would have a great effect on wildlife as 1000s of animals' homes would have been destroyed. It destroyed or extensively damaged over 200 homes, destroyed/ damaged 185 miles (300 km) of road and destroyed/ damaged 15 miles of railways. Airports closed (from 2days → 2 weeks). Over a thousand commercial flights were cancelled following airport closures. Lastly, unemployment rose rapidly after eruption.

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

May 18, 1980 was a day that dawned sunny and beautiful. Mt. St. Helens stood out beautifully against the blue sky. The mountain had been rumbling quite a bit the past few days, and geologists were watching it carefully and monitoring vibrations. There had been a series of earthquakes from around March 12, up until present day. Over 170 earthquakes hit that were higher that 2.5 on the Richter scale in that short period of time. The earth shook with an earthquake that hit 5.0 on the Richter scale, at around 8:32 in the morning. That did it. Mount St. Helens blew apart with the force of over 500 times more powerful than the atomic bomb. The lateral blast traveled at over 300 miles an hour, and destroyed 230 square miles of forest in just 3 minutes.

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.

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
