Description: Fact sheet of Mount St. Helens volcanic activity 1980 to 2000.
Mount St. Helens -- From the 1980 Eruption to 2000, Fact Sheet 036-00 U.S. Geological Survey Fact Sheet 036-00 Mount St. Helens, Washington, is the most active volcano in the Cascade Range. Its most recent series of eruptions began in 1980 when a large landslide and powerful explosive eruption created a large crater, and ended 6 years later after more than a dozen extrusions of lava built a dome in the crater. Larger, longer lasting eruptions have occurred in the volcano's past and are likely to occur in the future. Although the volcano seems to have returned to a period of quiet, scientists with the U.S. Geological Survey and University of Washington Geophysics Program continue to closely monitor Mount St. Helens for signs of renewed activity.
