Air filters for just about anything are flying off the shelves in Wasilla, Walmart is sold out of face filters.I was in Anchorage when Spurr erupted in 1992 and watched people panicking when they could not get air filters for their cars, turned out the ash that fell was much larger than predicted, actually like small grape nuts sized.
So far it looks like its heading straight for where I live up near Houston, I think I am 140 miles NE of Redoubt.
Looks like there could be some harmonic tremor now, though sometimes wind can look like that depending on where the seismomter is.
The last eruption in 1989 was preceeded by only 24 hours of high seismic activity. Really could go at any time.
Be safe Eye of Unk...prayers are w/you folks up in Alaska (and Gov. Palin).
