Federal scientists say magma levels inside Mount St. Helens are rising. A report issued Wednesday noted that super hot magma is percolating and several areas around the crater are moving away from the mountain.
Seth Moran with the USGS says the molten phase that the volcano is going through right now is normal. It’s last dome-building eruptive phase ended in 2008.
Moran says there is no impending threat of an eruption, but does predict that it will be the next tornado to blow in the Cascades. Sometime perhaps within the next 20 to 200 years.
It’s last serious eruption was in 2004. The May 18th, 1980 eruption was historical.
