I agree, YPP (Pitchstone Plateau) while normally a quiet sensor, has had some interesting activity Sat & Sun. The Yellow Stone region has had a lot of rain the past few days, which makes me wonder if that was a fault popping loose or a new one forming due to the rain. Also it is quite possible that enough water seeped down to where it got hot, and then started working its way up to a release point, breaking rock etcetera free as it did so, until it had a clear channel to vent out of.

I've not looked today just yet, but UoU is still working on events from the 20th.

Just looking at the wrapper today, while some of the really active sensors do have noise, (ignoring YMR) I think the signals on some of them have more amplitude than weather would account for. While it is raining at Old Faithful, the Mammoth web cam (where YMC is located) is dry....

That's a fairly common wave form there. The saw tooth bit comes from a distant quake where the signal echoes off the various mantles of the Earth. It is nothing to worry over, though it does grab your attention. We saw quite a bit of this type of wave form in Yellowstone as a result of the Indonesia quakes earlier this year. It is -not- a Harmonic Tremor if you were wondering if it was or wasn't.

More than likely this earthquake.usgs.gov... is the distant quake that caused it.

@ Shirakawa That makes sense, as there was rain yesterday. Truthfully I have no idea on how to pull a previous days data and run it on GEE, I suppose I'll have to sort it out one of these days.

Its Saturday Jun 27, time for a look through the sensors. (Prior to 16:00 UTC)

As it was mentioned already, YPP (Pitchstone Plateau) is being odd again. 09:50 UTC until 10:32 UTC.

YTP (The Promontory) Noisy signals.

YLT (Little West Thumb) has a signal at 12:30UTC - 12:37 UTC that is odd, and it has the odd signals from YPP @ 09:50 UTC-10:32 UTC. Also there is a small bout of the same sort of oddness at 15:43UTC - 15:48 UTC. (Which is too soon for it to be the Mid Atlantic Ridge quake at 15:45UTC.)

YFT (Old Faithful) seems to be picking up stuff from AK 12:30 UTC
onward.

YLA (Lake Butte) Got a calibration pulse at 08:32 UTC. Then it picked up some AK events after 12:32 UTC.

LKWY (Lakeway) It's Lakeway.

YML (Mary Lake) 13:41UTC - 14:22UTC long period of activity with two-four possible quakes in all of it.

YMR (Madison River) The update on the construction, on the YS web page, states that construction will continue until around Aug 26, 2009. Also that the road will be closed when they start work on replacing a bridge.

YDC (Denny Creek) If you look at the prior days activity and today's its fairly busy.

YUF (Upper Falls) Needs to be adjusted IMO, hopefully the UoU people can read it better than we can.
YNR (Norris Ridge) same as YUF
YPK (Parker Peak) Nada
YMP (Mirror Lake Plateau) Noise

YHB (Horse Butte) has the same signals as YDC. Could be weather related, could be something else. Looks interesting either way.

YJC (Joseph's Coat) Noise.
YMC (Maple Creek) Minor noise, probable distant event at 08:02UTC
YHH (Holmes Hill) Minor noise.
YSB (Soda Butte) Noise & possible weather related spikes.
YMV (Mammoth Springs) Noise, 14:41-2 UTC is from AK.
MCID (Moose Creek) Noise.

Back Later

Hi all,

Well YPP (Pitchstone Plateau) Major signal after 23:27 UTC, took an hour off and then started a slow build up from 01:30 onward only to wind down again by 02:00UTC.

This is the second or third time this signal pattern has shown up in the past few weeks for YPP.

This is Not normal behavior for YPP. Normal is little tiny bits and rare noise, YPP is generally the calmer of all the sensors.

The signal was most probably caused by a group of bisons passing by, going from YPP to MCID (see how the signal slowly fades in and out first at YPP and then at MCID).
