Mount St. Helens 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
There are many pro’s for attempting to forecast an earthquake or volcano. Forecasting an earthquake or eruption saves lives and property, mainly by preparation, as there is no way to prevent these events with today technology. On February 4th 1975 in Haicheng China there was a magnitude 7.5 earthquake. Over a period of months there were changes in elevation in land, ground water and unusual animal behavior which are all precursors to an earthquake. Days before the 7.5 magnitude earthquake there were
Mt. St. Helens is famously for its eruption on May 18, 1980, although the mountain had previous eruptions with four different stages and the stages often had similarities including the devastating one in 1980; in addition, the 1980 eruption presented serious havoc that led to a long road of recovery. The first stage known as the Ape Canyon Stage and according to the U.S. Geological survey it was ignited from series of small eruptions that created the birth of the mountain; during this phase these
erupted many times; from small-scale eruptions to cataclysmic ones; making them a force to consider about. Therefore the past is useful in predicting possible future eruptions as in terms of the effects they can have on civilisation, they are unpredictable in what they can produce. A super volcano is different to a normal volcano. The physicality maybe similar, but instead of one blast, they are a series of separate eruptions which then converge into one mega eruption. Each is a result of rising and
Johnston (Gunn 561). In 1980, Mount Saint Helens of the state of Washington erupted, filling the air with ash and causing mudflows powerful enough to lift tons. It decimated everything in its path. The eruptions, mudflows, and ash caused great damage on the landscape, yet it gave us information on how catastrophes happen and how they affect society and the surrounding landscape. The data acquired can also help us understand the way the landscape was formed. Mount Saint Helens caused much damage, but
Mountain” which is written by Ursula K. LeGuin. This story is a first-hand account of what Mt. St. Helens was like when it erupted. She also tells of news coverage and what she writes as well. She also writes people’s reactions as well as her viewing of the eruption like a giant pyrotechnics display. The third is a short poem entitled “Loo-Wit” and was written by Wendy Rose. This poem gives Mt. St. Helens a female persona and talks about it as if it were a living woman. It tells of how humanity
Mount St. Helens is a volcano that is located in the state of Washington. This paper will provide an overview on the volcanic eruption of Mount St. Helens that happened in May of 1980. This paper will also cover how this eruption affected the Earth, the damages and death tolls of this eruption, the economic impact, and any permanent consequences. Eruption of Mount St. Helens According to History – Mt. St. Helens (n.d.), approximately at 8:32 a.m. on May 18, 1980, a 5.1 magnitude earthquake happened
that we all live on. People have written stories of their disastrous eruptions, and painted their marvelous shapes on canvas. The essay will outline some of the more famous volcanoes and how they have impacted are history. Mount Vesuvius that destroy the great city of Pompeii, Krakatoa they spewed deadly ash on small village town, and Mount St. Helen, the only volcano in my own country to every erupt during my own time period. Mount Vesuvius is located in the Bay of Naples in Southern Italy. Its Latitude
Comparison to Mount St. Helens: “The Mount Fuji of America” is the nickname given to Mount St. Helens based off of its resemblance to Japan’s Mount Fuji. The last time Mount St. Helens erupted was July 10, 2008. Mount Fuji stands 4 thousand feet taller than Mount St. Helens. Mount St. Helens does not have a history like Mount Fuji does. St. Helens was not recognized as a volcano until 1835. In the eruption of 1980, which is the first eruption to date, fifty-seven people were killed and the eruption caused

On May 18th, 1980, one of the most prominent volcanic eruptions in US History took place in the state of Washington. Mount St. Helens had been dormant for almost 100 years before March 15th. On this day, two months before the eruption several small earthquakes shook the earth. This indicated a magma buildup below the surface, and the first minor event that would lead to one of the greatest eruptions the US has ever known. Following the first set of earthquakes, “Steam explosions blasted a 60- to
can be one of the most destructive forces on Earth. It is estimated that some 500 million people live near active volcanoes (Lutgens and Tarbuck, 2013). Of the Earth's known volcanoes, 70 can be expected to erupt each year with at least one large eruption each decade (Lutgens & Tarbuck, 2013). As populations continue to increase and more people are attracted to the beauty surrounding these areas, the immediate threat to humans from these sometimes sleeping giants grows. Due to this, the study of
when investigating natural disasters like earthquakes, and volcanic eruptions. It is also gives scientists the ability to understand how mountains were formed between two tectonic plates. There are three types of interactions between plate boundaries: convergent, divergent and transform. Looking back at the history of these three different interactions, earthquakes, like the one in Haiti, volcanic eruptions, like at Mount St. Helens, and the creation of mountain belts, like the Mid-Atlantic Oceanic
volcanoes. Key elements such as the worst volcanic eruption in history, can help researchers in the process of studying volcanoes. In addition, looking at the procedure in which volcanoes go through to erupt can lead towards a big discovery that can open new doors and new ideas. Over millions of years, thousands of eruptions have taken place across the globe; many of which are still active and erupting. Over the past ten years, about 550 eruptions have happened, about one happening every week
Mount Mazama was a stratovolcano in Klamath County, Oregon, until it destroyed itself. A stratovolcano is a volcano that has many layers. These layers are made of things such as pumice and hardened lava. The volcano was also a part of the Cascade Mountain Range. It is said that Mount Mazama started forming 420,000 years ago. The volcano started erupting more frequently and more violently 400,000 years ago, and stayed active for 70,000 years. Then one day 7,700 years ago, Mount Mazama had a huge
Super Volcanoes There is no exact definition for a super volcano, but the expression is often used to refer to volcanoes that have produced extraordinarily large eruptions in the past. When one of these large eruptions occurs, a huge amount of material is blasted out of the super volcano, leaving a massive crater or caldera. A caldera can be as much as forty or fifty miles wide. At Yellowstone, the caldera is so big that it includes a fair amount of the entire park
are active in any given year; about half of these are continuations of eruptions from previous years, and the rest are new. Mount St. Helen Volcanic eruptions in populated regions are a significant threat to people, property, and agriculture. The danger is mostly from fast-moving, hot flows of explosively erupted materials, falling ash, and highly destructive lava flows and volcanic debris flows. In addition, explosive eruptions, even from volcanoes in unpopulated regions, can eject ash high into the

slopes of volcanoes can be attractive to people setting up homes due to the rich, fertile soil 2. According to scientists, in the last 500 years approximately 20,000 people have died as a result of volcanic eruptions 3. A volcano is landform (generally a mountain) where, during an eruption, ash, gas and molten rock (magma) escape through the Earths surface 4. Approximately 1 in 10 people in the world live within danger range of an active volcano 5. Located on the planet Mars, Olympus Mons is
Volcanoes can block out the sun causing a ‘winter’, as we saw in June of 1816; the explosion in Indonesia, around the world, caused half a foot of snow in America. This same eruption also killed agriculture all around the world, leading to famine and killing even more people. To add to that, the eruption caused the cholera epidemic, killing millions of people around the globe. The San Francisco earthquake of 1906, happened along the San Andreas fault line in California, but was felt as
