Anyway, linguistic peculiarities aside, it sounds like the swarm of earthquakes may have been a precursor to less quirkily named geologic events. The Pacific Northwest Seismographic Network (which both UW and USGS are involved in) has issued a Notice of Volcanic Unrest. "Increased probability of explosions from the lava dome", even.
Terrafactive Armageddon indeed. When the earth rises up to throw off the shackles of her oppressors, it doesn't promise to be pretty. Ok, my tongue is pretty firmly in my cheek here, but I can see some of the millennialists having a field day. Earthquakes on the west coast, volcanos muttering to themselves under their breath; hurricanes on the east coast...
Do what you can to be safe, eh?
