Not surprisingly, the planet is stillringing from the quake!. Thought I heard something. (that's a joke, I do not think the seismicity is related, but what about that Full Moon at the time? )
This diagram (from the USGS) shows when you would have felt the P waves of the quake in minutes, unless you were in the shadow zone. I was some 150 degrees away at the time, in the area where some of those refracted P-waves converge. Heard a rumour that some wells in the SE USA recorded sudden vertical changes...haven't confirmed that. The second image is of the shadow zone.
But really, did you feel it?
On another topic, Singing dunes.... It's a neat sound!
Oh, let's not forget, St Helens is still at workand has been named Washington State's No. 1 air polluter!!!
Damn geology.
