Compare And Contrast Volcanoes And Mt St Helens
The two volcanoes from these events are called stratovolcanos, meaning they are volcanoes built up of alternate layers of lava and ash(citation), and cone shaped. Neither of these volcanoes are shield volcanoes, which are broad, domed volcanoes with gently sloping sides, characteristic of the eruption of fluid, basaltic lava(citation). Both of these volcano's had a huge impacts on humans, human structures and property, and had very high damage costs.

The major Mount St. Helens eruption was on May 18, 1980, in the state of Washington, USA. It's volcanic explositivy index reached 5 on a scale of 0 to 8. The Mount Pinatubo's eruption was on June 14, 1991 in the Cabusilan Mountains on the island of Luzon. It reached a 6 on the volcanic explositivy

    Shield volcanoes form when the products of eruption have low viscosity and are weak, so they do not pile up but spread. They are broad, gentle does that resemble a solder’s shield. Cinder cones are cone shaped piles of basaltic lapilli and blocks. Strato-volcanoes are large; cone shaped and is made of interleaved layers of lava, tephra and volcaniclatic debris. The prefix of its name emphasizes that they can grow to be kilometers high.…

    How Did Mt St. Helens Volcano Blast

    Helens, a stratovolcano, is located in Southwestern Washington. It is ranked 5 on the explosivity index. The eruption at Mount St. Helens was triggered by an earthquake that occurred at 8:32 am on the eighteenth of May, 1980. Scientists had been monitoring seismic activity for months before the eruption. When the volcano erupted, over 230 square miles were within the direct blast of the eruption. All 230 miles were completely totaled. Hot mud, which was moving at over 90 miles per hour, which cleared away everything that was in its path. The volcano, which used to be a symmetrical cone that stood at about 9,600 feet tall, is now horseshoe shaped and only stands at 8,300 feet tall. The landscape has been permanently altered since that day. More than 200 homes were destroyed in the blast. Over 185 miles of roads and over 15 miles of railways were also destroyed. Ash was blasted out of the volcano at over 650 miles per hour. Nearly 540 million tons of that ash drifted and settled over 2,220 square miles, reaching across seven states before finally ending in Minnesota. The cost to repair all of the damage caused by the eruption cost well over 1.1 billion dollars. It is considered to be the most destructive volcano in the United…

    Helens erupted. This eruption helped adjust historians’ idea of what happened to Mt. Vesuvius. Mount St. Helens experienced a pyroclastic flow causing the whole north side of the volcano to collapse. This event was extremely similar to the definition that Pliny the Younger provided to Mt. Vesuvius back in 79CE. Since these two eruptions were so similar, historians went back and tested remains of Mt. Vesuvius’ eruption. After the examinations, they finally concluded that the eruption of Mt. Vesuvius was a pyroclastic flow. Pyroclastic flows are dense mixtures of hot, dry rock fragments and hot gas. The temperatures of these rocks are extremely hot enough to kill a…

    Mount St. Helens Volcano Analysis

    First, we will discuss Mount St. Helens Volcano. Mount St. Helens is a stratovolcano located in the Pacific Northwest of the United States within Washington State. A stratovolcano is also known as a composite cone, which is “a large symmetrical structure that consists of alternating layers of explosively erupted cinders and ash interspersed with lava flows (Lutgens, 2012.)” Due to the cone shape of the volcano, stratovolcanoes are known for creating large explosive eruptions that can eject vast amounts of pyroclastic material. Mount St. Helens is a part of the Pacific Ocean Ring of Fire that spans across the ocean along the shorelines of continents that are located along the ocean. Within the Ring of Fire the mountain range which Mount St. Helens is a part of in the United States is called the Cascade Range. Of the 13 active volcanoes that are a part of the Cascade Range, Mount St. Helens is one of the more active volcanoes with its last major eruption occurring in May 1980 (Lutgens, 2012.)…

    On May 18th, 1980, in Washington State, the volcano, Mount St. Helens erupted. This eruption caused widespread terror throughout the towns surrounding the mountain. The magma from the volcano burned up the forest and killed most of the animals in the area. It affected the wildlife greatly because, after the eruption, the ecosystem was burned and smoldered thus killing thousands of animals in the region. This eruption was the deadliest of all the volcanic activity in the United States, and the people who live near the mountain are still affected by what the eruption did to this day.…

    To What Extent Can Volcanic Hazards Be Managed Effectively

    What followed this development on the volcano was the largest measured pyroclastic flow in history, travelling at about 230mph - which occurred on March 27th, 1980. Had there been people at work on the volcano’s face or lower slopes there would have been little hope for them, these lives were saved by prior planning and prediction of the eruption resulting in the evacuation of the local area.…
