Mount St Helens Research Paper
1. The name of my volcano is Mount St. Helens, it is located in Southern Washington State. Mount St. Helens is part of the ring of fire, a circle of active volcanoes that surrounds the Pacific Ocean.It is one of the most beautiful mountains in the Cascade Range, because It is a dormant stratovolcano many people will visit to play in the snow at it’s basen.
Mount St. Helens erupted on May 18,1980, The blast destroyed the top of the mountain and lowered it 1,300 feet, It is currently at 8,400 feet tall. Thousands of trees were blasted flat on the ground from the force.The volcanic ash cloud drifted east across the U.S.A. in 3 days. 2. Melted snow and Ice mixed with ash and rock created lahars a destructive mudflow on the slopes of a volcano …show more content…
Helens was formed within 1,460,000 days (40 years). The 1980 eruption was caused when magma formation beneath Mount St. Helens.The first sign of activity at Mount St.Helens occurred as a series of small earthquakes. Two continental plates, The Juan de Fuca plate off the western coast moving eastward and the North American plate collided.This volcano is well known for its ash explosions and pyroclastic flows. 4.Mount St. Helens Has produced four major explosive eruptions since 1479, and dozens more smaller eruptions.Producing pyroclastic flows,lava flows, and lahars. During the past 4,000 years, Mount St. Helens has erupted more frequently than any other volcano in the Cascade Range. Volcanic mudflows filled rivers with rocks, sand, and mud, damaging 27 bridges. Over the course of 17 episodes, lava eruptions began filling the crater, building a lava dome that reached 876 feet above the crater floor. 5. This project taught me a lot about volcanoes.Mount St. Helens remains a world-famous natural laboratory for the study of Earth’s processes and also nature’s response to catastrophe.Mount St. Helens will erupt a few more times,but they will be very small.The eruption in 1980 is the biggest eruption for mount St. Helens.I learned much more about this volcano than I knew
