USGS: Volcano Hazards Program CVO Mount St. Helens

On May 18, , a major volcanic eruption occurred at Mount St. Helens , a volcano located in Skamania County , in the U. The eruption a VEI 5 event was the most significant volcanic eruption to occur in the contiguous 48 U. The eruption was preceded by a two-month series of earthquakes and steam -venting episodes, caused by an injection of magma at shallow depth below the volcano that created a large bulge and a fracture system on the mountain's north slope. An earthquake at 8: This allowed the partly molten, high-pressure gas- and steam -rich rock in the volcano to suddenly explode northwards toward Spirit Lake in a hot mix of lava and pulverized older rock, overtaking the avalanching face. Less severe outbursts continued into the next day, only to be followed by other large, but not as destructive, eruptions later that year.

Mount St. Helens

The bulk of the pre— edifice of Mount St. Helens above about 1, m or 6, ft was constructed during the Spirit Lake Stage, which includes the most complex part of the eruptive history. Excellent preservation of deposits, and numerous ages from radiocarbon and tree-ring dating, provides considerable detail for this stage. Volcanism was intermittent, with lulls lasting from a few to about years. As in earlier stages, Spirit Lake volcanism erupted mostly dacite , but significant amounts of basalt and andesite were also erupted.
