    Hi everyone I'm Mary with Mary Greeley News.  Thank you for joining me. Here's an image taken  

  • 00:09

    from still camera photos put together showing Old  Faithful yesterday. Yeah the steam coming up um  

  • 00:19

    was a little dirty really windy there and you  can see the snow that came in during the night  

  • 00:26

    how quickly it melted that was on the ground  yesterday now according to another document  

  • 00:33

    that i found Yellowstone has been resurging  growing magma coming into the system for about  

  • 00:40

    three thousand years yeah there's some  buffalo moving across the boardwalk and  

  • 00:45

    back up over there this here is an image from  about eight o'clock in the morning yesterday  

  • 00:52

    um i wish I had some good news for you yesterday  yeah look how quick that snow starts to melt  

  • 00:58

    yesterday there was a surge of magma coming  into the system at Yellowstone lake particularly  

  • 01:07

    little west thumb here we have a spectrogram  provided by uh unabco.org of Yellowstone lake  

  • 01:18

    this is the surge of magma that i was coming in  that I was talking about let me pull it down a  

  • 01:24

    little bit so you can see yeah the deeper the  color red being hotter and blue being colder  

  • 01:33

    this here is grant the spectrogram they're  providing from the strain meter for grant  

  • 01:39

    and I've talked about grant yeah look how yellow  that went um how grant is an area where they had  

  • 01:44

    an earthquake swarm that the magma was trying to  break through the ground at this area is located  

  • 01:54

    by little west thumb this is one of the most  recent eruptions there they had at the park  

  • 02:00

    oh somewhere between 162 to 150 000  years ago down over here we have grant  

  • 02:09

    talked about the fault line you can see the blue  line that's a fault line that runs through here  

  • 02:14

    and I've talked about the fault line there at  Yellowstone lake where dike intrusion of magmas  

  • 02:19

    trying to break of rhyolite over here was me  tracking an earthquake swarm that occurred  

  • 02:27

    that was December 7th of last year Yellowstone  lake on the left Little West Thumb in the middle  

  • 02:35

    and Madison river here on the right look at  the activity at little west thumb yesterday  

  • 02:42

    this is that time frame right here  there's a lot of them marked in red for  

  • 02:47

    Yellowstone lake now we got one here let me  try and find them um what another one there

  • 02:56

    I don't know if it's there or what but there is a  lot of them a little concerning in what was going  

  • 03:04

    on yesterday borehole 208 for Yellowstone lake  x is north y is east this here is for the last  

  • 03:14

    seven days going down to the disk all  right so keep this in mind the magma  

  • 03:21

    is rising if you look at the ground towards  the north the north is rising up but the magma  

  • 03:28

    under the ground is flowing east so Yellowstone  Lake is east of grant now here is a diagram  

  • 03:39

    of the grant well borehole 944 it is uh 500 feet  under the ground let me pull it down for you  

  • 03:50

    the strain meter is 394 feet and the  seismometer is about 375 feet under the ground  

  • 03:58

    the top has a cap of cement so it does not  pick up any outside noise no stampeding buffalo  

  • 04:09

    no snowmobiles cars going over speed bumps  it will not pick it up all the bore holes  

  • 04:17

    there at the park are basically made the  same with about the same depth so here is the  

  • 04:25

    data from grant top is north for the  last seven days see how it took a jump  

  • 04:32

    x is north y is east and look at this look at all  the dots for quite a while the trend of the uplift  

  • 04:43

    was on the western side you can see that but now  it's kind of spreading out last seven days last  

  • 04:53

    30 days each time the ground goes up and down  it's been taking a breath that's what I call it  

  • 05:01

    and we got dots away here south and there's one  way over there north this is for the last 30 days  

  • 05:10

    the tilt meter for the north geyser basin area  borehole 205. it suddenly went down in the north  

  • 05:20

    but east is rising look at that how it's  breathing and look at the direction that is  

  • 05:27

    changing now remember Yellowstone lake is south  east from this location and it's showing uplift  

  • 05:36

    in the southeast this here is from the last  seven days and then we'll go to the last 30 days

  • 05:46

    There we go this is the trend it was doing  before kind of a south west now all of a  

  • 05:53

    sudden it decided it's going to go south  east see that yeah like I said it's a little  

  • 06:01

    disturbing another borehole from the Norris  geyser basin area borehole 950 top is north  

  • 06:10

    bottom is east last seven days and the  trend is going south east last 30 days

  • 06:23

    See how it was originally going north and  I've talked about this and now all of a  

  • 06:27

    sudden it's changing so using google earth  we'll go to the Norris geyser basin area

  • 06:39

    there we go up over there

  • 06:44

    kind of north west of Yellowstone and this  is the uplift that's showing a southeast  

  • 06:51

    direction which is let me pull it over

  • 06:58

    Yellowstone lake we have  uplift at Yellowstone lake  

  • 07:03

    we have two calderas over here at Yellowstone  lake we're actually close to it we have the  

  • 07:09

    sour creek resurgent dome and we also  have the mallard lake resurgent dome  

  • 07:15

    where the old faithful web camera that's supposed  to be live and it's not working is located  

  • 07:23

    they know the last time that Yellowstone  erupted it did a counter clockwise unzipping  

  • 07:32

    of the caldera coming from north west working  its way down towards the south towards heart lake  

  • 07:43

    and then both calderas erupted which caused the  collapse and the major eruption the last time  

  • 07:51

    of Yellowstone here's the monitors  for Yellowstone lake at the top  

  • 07:56

    little west thumb and maple creek look how  thick the magma was coming in at maple creek  

  • 08:03

    now this is what I monitor what's going on at the  sawtooth mountain I'll go ahead about four hours

  • 08:14

    show you all the activity

  • 08:21

    I'll pull it over so you can see the time you  can see how Yellowstone lake and west thumb  

  • 08:30

    have been highly active how thick the magma  is that's coming in there at sawtooth and I'm  

  • 08:39

    going to show you another paper that i found  look at all the earthquakes about the sawtooth  

  • 08:46

    and the snake river plateau is in fact all related  and we'll go ahead another two hours or four hours

  • 08:57

    Look at all those earthquakes and  this is what it's currently showing  

  • 09:01

    seismicity and earthquake hazard analysis of the  Teton Yellowstone region Wyoming they received the  

  • 09:08

    article in 2008 and became published in 2009 the  earthquake hazard in the Teton Yellowstone region  

  • 09:19

    is the highest in the U.S. intermountain region it  is not only influenced by lithospheric extinction  

  • 09:27

    associated with basin range tectonism  tectonics that extend 700 kilometers  

  • 09:35

    west to the sierra Nevada mountains California but  has the superposition of the effect of Yellowstone  

  • 09:44

    volcanic sources that can perturb stress up to  50 kilometers from the Yellowstone hot spot track  

  • 09:54

    the effects of Yellowstone hot spot has a profound  effect on seismicity not only on Yellowstone  

  • 10:03

    but on the surrounding fault zones of the  intermountain region the combine fault  

  • 10:10

    zones are part of the parabolic shaped zone  of produced earthquake activity surrounding  

  • 10:18

    the Yellowstone snake river plain volcanic  field the sawtooth mountain range 50 kilometers  

  • 10:28

    from the hot spot track let me pull that back  over and show you hot spot track 50 kilometers  

  • 10:39

    there's the sawtooth mountain range and we'll  follow it down to the snake river plateau

  • 10:49

    What we have here we got the Craters of the Moon  

  • 10:53

    and other volcanic fields so for 50 kilometers  out through this track where all these past  

  • 11:02

    eruptions we are still having the effect of  Yellowstone upon these fault zones all this  

  • 11:11

    information the documentation will be down below  in the more information box below this video  

  • 11:19

    this paper also has talks about how the valley  floor of Jackson Hole is rising up because  

  • 11:28

    of the unprecedented uplift that's going on at  Yellowstone and the effect it has upon the Teton  

  • 11:38

    fault zone which is drawn out here earthquakes  of the Teton Yellowstone region represent a high  

  • 11:46

    level of seismicity of the intermountain west  that is associated with interplay extension  

  • 11:53

    of the Yellowstone hotspot and the  surrounding region including the Teton  

  • 11:59

    and Hebgen lake faults and i mentioned the  area and i got Jackson Hole highlighted the con  

  • 12:07

    temporary deformation of the teapot Teton area  and its relation to the overall strain field  

  • 12:14

    of the Yellowstone region was assessed by GPS  observations 2007. the GPS field surveys from 1986  

  • 12:25

    to 2000 indicated the unexpected results namely  that the valley of Jackson Hole is moving upward  

  • 12:36

    with respect to the Teton mountain block  and principal horizontal extension strain  

  • 12:42

    axis is generally particular to the fault  

  • 12:47

    this observation implies crustal shortening and  compression of the Jackson Hole valley crust  

  • 12:54

    against the fault but more importantly the  observed westward valley motion from the station  

  • 13:02

    closest to the Teton fault supports the idea  that the fault may be locked in compression  

  • 13:10

    which means pressure is building for a large  earthquake anyway there there was extensive  

  • 13:16

    magma coming in from the snake river plateau  that's what i got here on the right showing  

  • 13:24

    the thickening of the lines the magma coming in  and I'm going to make this other two monitors  

  • 13:31

    larger so you can see the earthquakes little west  thumb on the right Yellowstone lake on the left  

  • 13:39

    each line in red indicates an earthquake that  the earthquake monitors the computers picked up  

  • 13:47

    sends a signal for the geologist to come in  and review it trying to find where these are at

  • 13:56

    let me close this out you can  I hope see them all in red okay  

  • 14:03

    this is the one that was the most  significant there at west thumb  

  • 14:08

    we've got another one right there and we'll go to  the signature see that let me go back over here

  • 14:28

    Anyways that's all I have for you  right now sorry it's not good news  

  • 14:33

    uh please put your thoughts your comments your  questions I hope you are all prepared for any type  

  • 14:38

    of major disaster we got tornadoes we got floods  animals being found where they shouldn't be found  

  • 14:46

    um earthquakes and diverse locations put your  questions and comments down below please stay  

  • 14:53

    safe and I'll talk to you  later. God bless y'all bye
