Mt St Helens Essay

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 St Helens erupted on the 18th May 1980 at 9am and is an active strata volcano Washington State USA, a MEDC. Where as on 18th July 1995, during the daytime, Montserrat, a LEDC during the day, Montserrat's Soufrière Hills composite volcano of a height 1050m, meaning sulphur hills, dormant for centuries, erupted and produced a phreatic eruption. The volcano is a strata volcano also. Mount St. Helens is a composite volcano which lies near to a destructive plate boundary where the small Juan de Fuca Plate is being subducted underneath the North American Plate where as the eruption

St. Helens, and how it changed. It was beautiful, before the eruption. Mt. Hood was jagged, and Rainier was a funny shape. But Mt. St. Helens was a perfect dome, snowcapped, with Spirit Lake spread out far below. I remember a man telling me that they thought a bomb had gone off. It shook the house. They thought maybe next door the neighbors were setting off fireworks. They lived over 90 miles from the volcano. All of the streetlights came on in the middle of the day, as a fine layer of ash darkened the sky. People living near the volcano were simply smothered under a heavy

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.

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.

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

Mount St. Helen is a very active volcano classified as a stratovolcano, stratovolcano is basically a tall volcano built up of layer after layer of hard lava, tephra, pumice, and volcanic ash. Mount St. Helens location is in Skamania County in Washington, with coordinates of 46 12'00.17"N122 11'21.13"W. Mount St Helen is famous because of its catastrophic eruption on May eighteenth in nineteen eighty. The eruption measured a five on the volcanic explosivity index. This is an index created by Chris Newell and Steven Self in the year nineteen eighty-two it was designed to try and measure the explosiveness of volcano eruptions to determine the value of the explosivity and qualitative observations ranging from zero to eight, eight being the

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.

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.

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.

The first historic eruption of Santa Maria was the second largest volcanic eruption in this century. It was the third large explosive eruption in 1902. Mount Pelee and Soufriere of St. Vincent erupted six months earlier.” It also states that “The 1902 eruption of Santa Maria lasted 19 days.” Latitude: 14.76, Longitude: -91.55, Elevation: 3772, Country: Guatemala, Type: Stratovolcano.

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.

Volcanoes are one of the most destructive, yet, most beautiful things on Earth. They can make a famous city choke in its own ashes in one day, like Pompeii. Or they can turn a once damaging mountain into a graceful and peaceful home for new life, like Mount St. Helen’s. All volcanoes are unique, and no two are the same. Some erupt differently than others, some look different than others, and all are located in different spots all over the world. I learned this while completing the project and the five volcanoes I researched are examples of my discoveries. The five volcanoes I researched were Mount Hood, Mount Mageik, Long Island, Mount Muria, and Las Pilas.

Ash plumes and steam rose into the bright blue sky as the underground earthquake shook the land and rattled windows all across the eighteen mile town. As the jet circled the island, in view of lovely beaches and emerald water, looming over this lush paradise was the screaming volcano. Volcanos erupt when the pressure inside of them becomes so great that the magma surges up and forces its way out. An exploding volcano can rip apart a mountain in just seconds, when the eruption is over, a landscape is changed forever. The united states is home to more volcanos than any other country except Indonesia, and Japan. The majority of these volcanoes are in Alaska. Until recently, there was no way to predict when a volcano would blow, although volcanoes give off many warning signs before they erupt. Including smaller earthquakes beneath the volcano, slight inflation, or swelling. The rising magma eventually causes the solid rock to break, sending earthquake signals. Most volcanoes give warning signs beginning weeks or months before they blow (Lindop).
