Yeah... weird how those pipecleaner thingies nearly always seem to fizzle out when other activity kicks in. They don't just shut off, they sort of
fizzle out like anorexic caterpillars...
Happened so often before it no longer surprises me.
To
TrueAmerican: hey, nice observation on those E, Z, and N readings from GEE.
Now, if the signals are coming in strong on E and Z, but
there's almost nothing on N, in terms of simple mechanics it pretty well describes the vibration we'd see from a somewhat out-of-balance object
fixed on a rotating shaft. If the E component is strongest it'd be like a piston running in a horizontal plane at right angles to the shaft; if it's
the Z that's strongest then it'd be vertical, but of course still at right angles to the said shaft. A slightly out-of-balance wheel might give the
same effects but they probably wouldn't be as pronounced.
Now I'm not saying it has to be a piston or wheel etc, just trying to visualize what types of things there are that would produce vibration along a
horizontal and vertical axis but with no real axis of depth, if you follow.
If it's a pumped danged if I know why it gives such odd traces when other seismics start up, or why it varies in intensity so much, or even why it
sometimes seems to be triggered by teleseisms, but it's hard to think of a natural phenomenon in that environment that would produce such an odd bias
in the traces -- so, have to go with you that either it's something mechanical or else by some very slim chance it's just something totally weird
and unknown...
That's funny.. why do I hear the X-files theme?
By the way all, I checked around on the web and could only find records/reports for two air monitors in YS. One's by the entrance road coming from
West Yellowstone township, and the other is just by Old Faithful. Couldn't find any reports for readings from a station near YS Lake.
Has anyone found any data/reports for an air monitoring station there? Not anecdotal evidence of the "I heard about one" kind
, but actual
reports?
