Good summary. I just saw much the same reports on KING5.
The local eggheads did say that it had all the appearances of being tectonic, not volcanic. And that they were busy putting together a few more stations on the mountain.
There has been a mini-cluster of micro quakes in the Puget sound area lately, something like 60 of them in the last few weeks. King5 had said they might be related to the deep underground quake cycle, that runs ever 14 months or so and is due to start around the beginning of November.
BTW, there is a new sign near where I live, it's the "Volcano Evacuation Route" sign.
The arrow on it points down the hill towards Puyallup!
If/when that puppy goes, I don't think I'll be in any great rush to go to Puyallup!!
LOL! Yeah No Kidding!
