Mt St Helens Essay

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. Sending a volcanic surge directly at St.pierre's at a rate of 420 miles per hour.Killing 30,000 people in its wake.National National Geographic News”Deadliest volcano of the 20th century, 100 years later””molly pell and channo wOodage for National Geographic News, 5-8-2”

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.

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.

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

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.

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.

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

Historic Eruptions: 1902 Destroyed the whole village of St. Pierre. On may fifth a lahar reaching 100 km per hour came down mount Pelée and killed 2 dozen people. Also material spilled into the ocean and caused a 3 meter high tsunami the “inundated” St. Pierre. The most devastating thing was that snakes and insects (that some where venomous) came down the volcano and into the village. Soldiers lined up on the streets to shoot the snakes but they weren’t able to save the city. There’s debate about exactly what happened on May 8 — Ascension Day — but one thing is certain: In the course of a few short minutes, an infernal blast of hot gas and volcanic debris obliterated

He wrote several major publications on the topic, including his doctoral dissertation on Mount St. Helens. In 1991, while conducting avalanche research with volcanologists Katia and Maurice Krafft on Mount Unzen in Japan, Glicken was killed by a wayward pyroclastic flow. Glicken and David A. Johnston (who died at Mount St. Helens) remain the only American volcanologists known to have perished in volcanic eruptions. After Glicken's dissertation was published by his colleagues in 1996, the report was widely cited. His detailed and comprehensive work on flows at Mount St. Helens is considered the most

Have you ever heard of an earthquake? an earthquake is shaking or trembling of the ground. on January 12th 2010 a tragic event occurred in an island called Haiti. it was one of the highest rank earthquake that happened in over centuries. it was rated 7.0. million of dollars worth of damage, the even killed over a quarter million and left countless Haitians on the streets homeless. many had no homes because it was destroyed, today six and a half years later the people of the island still live with physical and mental scars from the tragic event ( Gael Turine , times.com , November 28 2014).

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).
