Full Answer

Mount St. Helens is classified as a stratovolcano and its elevation is 8,363 feet above sea level. Over 1,300 feet of the volcano was removed during its 1980 eruption. That blast, which occurred on May 18th, affected 229 square miles of land and several million dollars worth of timber. As of 2014, it was the deadliest and costliest volcanic eruption in United States history. Two volcanic eruptions occurred in the continental United States during the 20th century: Mt. Lassen in 1915 and Mt. St. Helens in 1980.
