USGS: Mount St. Helens could erupt within 24 hours
Observatory 3 miles from volcano's base evacuatedScientists warn that Mount St. Helens could erupt within 24 hours, and with more force than previously expected. Saturday afternoon, the U.S. Geological Survey issued a Level 3 Volcano Alert, indicating an eruption could occur within the next day, said Tom Pierson with the USGS. That level alert is the third of four -- with the fourth being eruption. The alert was issued after scientists detected the movement of magma, or underground lava, the USGS said.
