Helens is feeling a bit left out. We've been paying lots and lots of attention to Rainier for the past month. Although....while this is in the helens seismic zone, it sits almost smack dab in between helens and Rainier.

That doesn't change the fact though that they really don't know.

helicopter......schmellicopter. Never in a month of sundays does a helicopter make a gliding sound like that at 11 Hz. Nor does a helicopter take 6 minutes or more to do a pass, and if it was hovering the sound would not vary.
(Of course I could be wrong - nah perish the thought)
ETA: Last thought before I close down. The helicopter signal they show looks like a shortened version of the trains, which is exactly what I would expect, and the trains sounded NOTHING like this sound. The harmonic may be from the glacier. I am not saying it is magmatic HT, but HT it is.

but I hearby CEASE any assertion that the icequakes are anything other than that.
And now I must make another choice. And I am going to make it publicly, right here, and right now. Because it is fair to reveal this information, in my opinion, so that everyone knows.
The PNSN, as well as several other seismic networks, are very well aware of ATS and the things we discuss. I will not speculate as to the reasons they may, or may not, participate anonymously. Of that I have no clue.
I just wanted to make the point, so that some measure of respect IS shown to them in responses. On the other hand, they may enjoy getting pummeled, laughed at, and heckled.
