http://www.komotv.com/stories/36112.htmVANCOUVER, WASH. - Clouds have prevented scientists from seeing what's going on Monday at Mount St. Helens, but the seismographs are starting to perk up a little.
There have been three quakes Sunday night and early Monday greater than magnitude 3 -- the largest being 3.4.
A spokesman for the University of Washington seismology lab, Bill Steele, says the quakes "do seem to be getting a little bit larger and that's of interest, but what it all means we don't know."
Steele says there has been no confirmed steam or ash plume from the latest activity, although he says that's a possibility. He says there also may be rockfalls in the crater or magma pulsing onto the crater floor.
