___I am ever ready to say the sky is falling, & today is no exception except I realized my error before shouting out. It is my habit over the last 2 or so years to visit the seismogram readouts in my region every day at least once. One particular type of pattern that the experts say is significant is the 'harmonic tremor', the trace of which has a steady rythym over a long period as opposed to the sharp spike & shortish decline of a typical quake.
___So today, I see this apparent harmonic signature at Mt. Hood & actually quite a few stations on volcanoes in the PNW. Heres a link to the Hood trace; note the activity which begins about 11:00 am.

___Now comes the 'hold it a minute' clause. I just watched the local weather & the predominate feature throughout the region today is high wind. So, I now beleive that the trace reflects a wind induced harmonic signature which is not quake related.
___Fascinating to have so much real time data at one's disposal.
