Is Yellowstone Showing Harmonic Tremors?

Is Yellowstone Showing "Harmonic Tremors"?

I am posting this because I have noticed changes in the quakes that at Yellowstone.

http://quake.utah.edu/helicorder/ymr_webi.htm

If you look closely at the graph you will notice a small set of squiggles just before a shock. the largest happened at around 00:15 plus theses quakes are not being reported on there up date sights.

Harmonic tremor is a sustained release of seismic and/or infrasonic energy typically associated with the underground movement or venting of magma and/or volcanic gases. Being a long-duration continuous signal from a temporally extended source, volcanic tremor contrasts distinctly with transient sources of seismic radiation, such as are typically associated with earthquakes and explosions.

What gets me is there not constant how ever they are signal before a quake.

So I would like a professional to look at this one that has no agenda and please don't tell me it was to do with a vehicle unless you can provide me a maintenance log. I also have charts but the few I have doesn't cover the ones I am looking at.

Those are not harmonic tremors, but rather "tremors" or seismic noise, Harmonic tremors have repeated sig of cigar-shaped packets echoed repeatedly: De-gassing is HT "chugging".

I have trouble giving this any credit considering the errors using "sight" instead of "site" and "there" instead of "they're", "doesn't" replacing "Don't" and other grammatical abominations.

It happens every time you put quarters in the motel room's vibrating bed, huh?
