    Very weak tremors (the webicorders resolution not good enough to tell if harmonic tremors or not) Friday night going to sat. morning. With another tremor event around noon. A few more quakes, and... the very weak signature of rock breaking here and there. The spectrograph from one station is very very similar to the low freq spectrograph of ETS tremors. So I'm going to say it. It looks to be low frequency harmonic tremors.

    There have been no reports of deformation, increases in gas emissions, or changes in Newberry's hydrothermal system. So while tremors are interesting, they don't indicate any threat as of yet.

    More Quakes, about 2-7 a day Average, so it's not a rate to be worried over. More Tremors, and a bit more frequent, they are starting to show on the webicorders better, so they are increasing in strength, slightly.

    Ok as much as I am not an alarmist when it comes to volcanoes, this one has got my attention. Starting at about 8am this morning, just after I posted, there was a swarm of tremors. Not Quakes. This went on for 8 hours and cumulated in a 8 minute long harmonic tremor. http://pnsn.org/seismogram/2014/10/1...%3A00%3A00+UTC

    Again the wind history records don't match the webicorders, so I'm going to say it...

    Chance of magma movement: 95%
    Chance of cinder cone minor eruption (VEI < 1): 2%

    The recent flurry of quakes, and the apparent tremors, are being reported as 'Stimulation of the Hot Rocks', by AltaRock Energy's Hydrothermal operation. Which seems reasonable, the tremor swarm yesterday matches a period of water injection (hence the 8am to 4pm time line of the swarm).

    So standing down on my chances, but going to keep an eye on this.

    Ahh, so they found some funding and got their well fixed. Good.
    Here's their latest blog entry: Update from the Field: Stimulation Underway Oct. 14, 2014

    The Swarm and Tremors have stopped in the last weeks, coinciding with the pumping in of the heat-degradable sealant, and then the waiting for that to take effect.

    AltaRock's Newberry blog
    Progress appears to be glacial, but is ongoing.
    Latest is that DOE may be building its own geothermal lab near the volcano. (see blog).

    We thought about making another visit to Newberry during our recent road trip but wound up spending a couple of days in a larger caldera instead -- Yellowstone!

    This won't be mentioned in any USGS or Volcano blog, but Chugging was detected at Newberry on the 18th. Attaching the Seismograph image. Chugging typically only occurs when fresher (hotter) magma is injected in an area with cooler magma, causing the cooler magma to Boil. Chugging is kind of similar an old fashioned coffee pot. Nothing to worry over though. It showed up on 7 of the 14 seismographs in the area, the cleanest and strongest coming from the central station in the caldera.
