Both of these volcano's had a huge impacts on humans, human structures and property, and had very high damage costs.

    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…

    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.
