Volcano seismic activity resumes
MOUNT ST. HELENS, Wash. (AP) - Scientists say there could be more steam eruptions on Mount St. Helens where seismic disturbances readings resumed within hours of Friday's steam blast on the volcano.
That suggests that pressure is building up inside the mountain again -- meaning another steam blast could happen, possibly soon.
Friday's noontime eruption was not without cost. It destroyed the seismic and deformation stations on the dome. Scientists use the gear to track ground movement.
U-S Geological Survey hydrologist John Major says futher measurements are going to have to be done by eye.
Friday's steam and ash eruption came more than a week after a flurry of earthquakes warned the volcano was reawakening, but it was nothing like the 1980 blast that killed 57 people.
