kgw.com News for Oregon and SW Washington Local News: "The rumblings at Mount St. Helens have been so strong, the lava dome has collapsed. Scientists are trying to figure out what's behind the recent string of stronger-than-normal quakes at the volcano.
In the last 24 hours, the seismograph has recorded three earthquakes with a magnitude at or near 3.0, and these quakes are shaking things up inside the crater. St. Helens is at it again, shaking and rattling and sending the seismograph needle into overdrive.
Compare a printout of the mountain at rest and of St. Helens in the last several weeks, and you'll notice a striking difference. 'At least one 3.0 magnitude quake everyday.' What do these rumbles mean? Are they a preview to the next big one? Experts are not sure."
