Mt. St. Helens 1980 EruptionMt. St. Helens’ 1980 eruption took place in Washington on May 18, 1980. It was the deadliest volcanic eruption in the U.S.. The eruption lasted for 9 hours, thats a long time! During the eruption, the volcanic ash fell as far as 930 miles away from the volcano. The eruption killed fifty-seven people, two-hundred fifty homes got damaged, two-hundred miles of highway were destroyed, and two-hundred fifty square miles, gone! The first animals to return after the eruption were beetles and spiders. The whole 1980 eruption costed $1.1 billion of damage - that’s a lot of money!

History of Mt. St. HelensMt. St. Helens was first discovered by the British Commander, George Vancouver of the H.M.S Discovery while he was on his ship exploring. George Vancouver also named Mt. St. Helens after Baron St. Helens, the ambassador of Spain. Native Americans in the Pacific Northwest used to call Mt. St. Helens “Louwala-Clough”, or in other words, “The Smoking Mountain”. Thomas J. Dryer was the first person to climb to the top of Mt. St. Helens on August 26, 1853. A magnitude 5.1 earthquake awakened the volcano after 123 years. The 1980 eruption of Mt. St. Helens was the worst volcanic disaster in U.S. history. August 1980, Mt. St. Helens became a National Volcanic Monument covering over 110,000 acres. Mt. St. Helens is historically the most active volcano out of the Cascade Range

Geography of Mt. St. Helens Mt. St. Helens is located in Southwestern Washington. Mt. St. Helens is about 8,363 feet high and its base is 6 miles long - that’s really big! Geologists call Mt. St. Helens a stratovolcano. There are three main rivers in vicinity of Mt. St. Helens - the Toutle, Kalama, and Lewis rivers. Most of Mt. St. Helens is 3,000 years old. When Mt. St. Helens erupted in 1980, it created an ash cloud and a lava dome. A day after the 1980 eruption, there was a landslide. The 1980 eruption was also followed by a 2 month series of earthquakes. Oh, and did you know that a volcano is a vent in the earth’s crust that molten rock or magma is ejected?
