Mount St Helens Earthquake Research Paper

Re-live the stories of the Lewis and Clark expedition! Packed with well-known stories from America’s past, St. Helens, Oregon is sure to intrigue even the most educated historian. Founded in 1850, St. Helens still works to provide plenty of entertainment for its residents and guests. With rent to own homes available you will definitely want to come join the crowd during the annual Kiwanis parade in June or become a part of the big Annual Celebration in September.

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.

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.

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.

After more then 40,000 years of activity, one would expect that people would no longer live in the surrounding shadow of Mt. St. Helens. But regardless, many towns and cities sit inside of a zone that would face destruction if a large eruption took place. In 1980 Mt. St. Helens erupted and caused the loss of many lives and the destruction of thousands of miles of land and property. Following the eruption, the volcano has stayed extremely active. In 2004 it erupted again, building a new lava dome and sending ash and steam into the atmosphere. Since then, seismologists and volcanologists have recently discovered pockets of magma rising and that another eruption may occur soon. Even though the people of Washington know that an eruption could cause widespread devastation they continue with their lives, doing little to prepare for the potential disaster.

To begin with Mt. Vesuvius was one of the most deadliest volcanoes we’ve ever known. To prove that statement Mt. Vesuvius is the only known active volcano on the mainland of Europe. It is known for the eruption in A.D. 79 that wiped out the city of Pompeii and the city of Herculaneum. The people were just doing their everyday thing, when Mt. Vesuvius which they didn’t even know was a volcano exploded, sending lava flowing towards Pompeii and the city of Herculaneum. If you look at the casts of the pompeians, they look more frightened than any other person would. Mt. St. Helens is known for it’s explosive 1980 eruption. The has been the most active volcano in the Pacific Northwest. About

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.

In this report, we will talk about Mount St. Helens and how it is related to volcanoes. In the video about Mount St. Helens, geologists let us know why Mount St. Helen’s is the most deadly volcanic blast in the U.S. Mount St. Helens is a large eruptive cone and is a type of composite volcano that the volcano is composed of many layers of volcanic rocks. The video starts by informing us that this volcano is one of the biggest landslides. In addition, it let us know that volcanoes are dangerous and deadly because they are so hard to predict. Mount St. Helens is located in Washington State and forms part of the Cascade Mountain Range at the North American West Coast.

Helens was a huge eruption that happened May 18th, 1980. 57 people died from the smoke. By April it was growing 5ft per day. The mushroom clouds of ash and gases more than 12 miles into the air.” states livescince. “The shock wave went 19 miles” state's fs.usda.gov. Such pulse indicated magma was on the move. On May 18, there were hundreds of earthquakes that day. The eruption lasted 9 hours. The Mount St. Helens erupted at 8:32 A.M. It went as high as 1,300 feet (396 meters). Biggest eruption over 100 years. “The first eruption of steam from the summit sent a column of ash, snow and, steam 6,000 sent into the air”, livescince.gov There were a lot of things going on that day and

Volcanoes are classified with the Volcanic Explosively Index (VEI) scale. Mount St. Helens was ranked at a five, the highest is an eight. The volcano erupted at 8:32 AM May 18, 1980. In all fifty-seven people died, twenty-seven bodies were lost, and the surrounding town was wiped out. After the explosion there was a massive mudslide.

Mount. St. Helen’s Eruption There been many volcanoes that have killed more people than Mount. St. Helen’s, but this is the deadliest in the U.S. this volcanic eruption caused mass destruction. May 18,1980 was a tragic day, but in the end almost everything was back to normal in Skamania county, Washington. As it ended it was going to change everything.

Before May 1980, Mount St. Helen in Washington State ha been quiet for over a hundred years. It had been calling "the Fuji of America " because it's symmetrical cone resembled the famous volcano in Japan. It's massive eruption on Sunday, May 20, 980, changed that shape. Mount St. Helens lost 3.7 billion cubic yards of rock. Volcanic ash was send fifteen miles into the air, and very hot winds blew in all directions. Two hundred thirty square miles of forest were flatten. Seventy percent of the snow and ice on the mountain melted, causing an enormous landslide of mud, volcanic ash, rocks, and trees to speeding down the mountain at 500 miles per hour. In the eruption, fifty-seven people lost their lives, some as far away as thirteen miles from the mountain. Most of them were scientists, loggers, and journalists.

There were minor eruptions in 1898, 1903, 1932, and most of the 20th century. None of these came close to the damage that the 1980 eruption caused. The eruption lasted over 2 months and caused that one side of the slope being the north side was destroyed from the magma. This volcano had ash flow into 11 different states. Out of the 11 states that experienced it’s eruption, 57 people died due to the eruption of Mt. St. Helens. Some state highways and roads had to be closed and highway repairs alone run into hundreds of millions of dollars. Many pieces from the mountains were rushing down the mountain and onto the ground at 300 miles per hour. Trees, some 200 feet high, were stripped of branches and bark. Some old growth trees

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.

     An Earthquake is the shaking of the earth's surface caused by rapid movement of the earth's rocky outer layer. The sudden shaking of the ground that occurs when masses of rock change position below the Earth's surface is called an earthquake. The shifting masses send out shock waves that may be powerful enough to alter the surface of the Earth, thrusting up cliffs and opening great cracks in the ground.
