  • Chicken-egg question arises over quakes, rockfall from rising dome 2005-Jul-21 13:24 from The Portland Oregonian

    SEATTLE (AP) — There's a whole lotta shakin' going on at Mount St. Helens these days as the restless peak does what it has for thousands of years: build new lava domes for itself that totter and fall and then serve as the foundation for future domes.

    A series of stronger than usual earthquakes — exceeding magnitude 3 — has been reported in recent days by the Cascades Volcano Laboratory in Vancouver, Wash., about 50 miles south of the mountain. The latest was a magnitude 3.1 quake early Thursday that was accompanied by a rockfall.
