No Biggie

There have been a few reports today, in OregonLive, KGW and KATU, about a series of small quakes at Mt. St Helens over the weekend.
There were 15 quakes, mostly in the magnitude 1 range, with a couple around magnitude 2.5 recorded by the Pacific Northwest Seismic Network. They were about two miles deep just northwest of the volcano.
Small swarms like this are not uncommon under any of the major Cascade peaks and the surrounding area. All three reports appear to be based on the same AP source, and all agree that this shouldn't be taken as a warning of any incipient St Helens activity. On the other hand, if you're in the vicinity of Yellowstone, you might want to hightail it out of there. In fact, I'd like to recommend that any geological activity, anywhere on the planet, should be taken to indicate that the terror threat at Yellowstone has risen from red to at least crimson, and very likely ultraviolet.
