    There is some good news that would come out of it if Yellowstone did the full blown number, we wouldn't have to worry about obama signing anti-firearm laws!

    Can we just move the capitol building right on top of Old Faithful? :): It would make a good Lobby piece....

    just an update.

    Though nothing on the map (http://earthquake.usgs.gov/eqcenter/)today. There was a very large quake (http://www.quake.utah.edu/helicorder/heli/yellowstone/Uuss.YPP_EHZ_WY.2009011100.gif)at least a 3.5-4.5m recorded on 2 helicorders(second is around 40 miles away here (http://www.quake.utah.edu/helicorder/heli/yellowstone/Uuss.YML_EHZ_WY.2009011100.gif). Also of note the lake with all the earthquakes since the 27th of dec has been taken down since the 9th (http://www.quake.utah.edu/helicorder/heli/yellowstone/Uuss.LKWY_SHZ_US.2009010900.gif). Just saying.

    Since all relevant webicorders seem to be down I found another source of information :) The University of Utah. You can see quakes for the last 24 hours last week ect. One thing I can not help but notice is that none of the quakes listed on this map for the last week are on the USGS site.

    Circle City Pundit.com: Is Yellowstone about to pull a Vesuvius?

    Is Yellowstone about to pull a Vesuvius?



    Apparently, a recent increase in earthquake activity at Yellowstone National Park is renewing concerns about the supervolcano in which the park sits:
    Hundreds of earthquakes have hit Yellowstone National Park, raising fears of a more powerful volcanic eruption.

    The earthquake swarm, the biggest in more than 20 years, is being closely monitored by scientists and emergency authorities.

    The series of small quakes included three last Friday which measured stronger than magnitude 3.0. The strongest since this latest swarm of quakes began on December 27 was 3.9.

    No damage has yet been reported but scientists say this level of activity - there have been more than 500 tremors in the last week - is highly unusual.

    "The earthquake sequence is the most intense in this area for some years," said the Yellowstone Volcano Observatory. Some of the larger earthquakes have been felt by park employees and guests, according to the observatory.

    The swarm is occurring beneath the northern part of Yellowstone Lake in the park. Yellowstone sits on the caldera of an ancient supervolcano and continuing geothermal activity can be seen in the picturesque geysers and steam holes, such as Old Faithful.

    About 1,000 to 2,000 tremors a year have been recorded since 2004. The most devastating earthquake in recent history in the Yellowstone region occurred on August 17, 1959, when a magnitude 7.1 earthquake hit.

    It was centered near Hebgen Lake, Montana and it caused landslides that killed 28 people and caused more than $11 million in damage.

    Geysers in Yellowstone National park changed eruption times, and new ones began to erupt. On June 30, 1975, a magnitude 6.4 tremor hit the park.

    Professor Robert B. Smith, a geophysicist at the University of Utah and one of the leading experts on earthquake and volcanic activity at Yellowstone, said that the swarm was significant.

    "It's not business as usual," he said. "This is a large earthquake swarm, and we've recorded several hundred. We are paying careful attention. This is an important sequence."

    The last full-scale explosion of the Yellowstone Supervolcano, the Lava Creek eruption which happened approximately 640,000 years ago, ejected about 240 cubic miles of rock and dust into the sky.

    Geologists have been closely monitoring the rise and fall of the Yellowstone Plateau as an indication of changes in magma chamber pressure.

    The Yellowstone caldera floor has risen recently - almost 3in per year for the past three years - a rate more than three times greater than ever observed since such measurements began in 1923.
    Hugh Hewitt, who calls Yellowstone "An Inconvenient National Park," has a roundup, including a handy-dandy map. I like maps.

    Update.One hour ago a 7.4 hit east of the KUri islands(Russia). 38 min ago there was a 3.2 south of yellowstone. 15 min ago there was a 3.7 and the webicorders are all over the place(they are going to report more quakes soon...they need time to process the magnitudes and make them "official".
    links Kuri,then yellowstone then webicorders.

    Magnitude 7.4 - EAST OF THE KURIL ISLANDS
    Earthquake List for Map Centered at 42°N, 110°W

    Also VERY important and worth mentioning. Look at the history on the webicorders. When there is a quake it shows up normally on 1-4 of them.This is because the plates under Yellowstone are very broken up and the seismic waves do not travel well in them.You can see this pattern in all webicorders recorded quakes as far back as you can look.A quake shows up on a few recorders. The last two quakes are on ALL of them.
    The two I am talking about are 1-15 at 11 and 1-15 at 21:15

    One somewhere is going to go soon. Probably not Yellowstone, but a big one, somewhere, if this keeps up.

    Update of the last week or so in first link,second link is last month.
    Earthquake List for Map Centered at 42°N, 110°W
    There was a quote "minor" 3.3 yesterday recorded on 18 seismographs.

    And of course the helicorders do not lie(wonder why they do not list these quakes?less than 1/3rd of these are listed...this is due to "only officially verified quakes are listed" a freaking 5 year old can learn to read these.)

    What about the Alaskan 'Cano? Ain't she about to pop? I'm more worried about that at this point...

    sure is. here is a link to Alaska.
    Alaska Region
    But Alaska is much harder to read. few seismographs and next to no public data(ie it is all USGS data). I do not think it would effect the lower 48 1/1000th of what Yellowstone would if it blew.I know most people do not understand.Yellowston is more active in the last 2 months than at any time since recording there began. yes there have been bigger quakes,but even those are few and far between.The ones they are having now are daily. Even the USGS is keeping a close eye on it.Here is the "press release". Notice the last update was january 9th and they had a 3.3 yesterday.
    Volcano Information
    Also look here for historical and current data. Notice how they call current swarms normal,but in 2006-7 they say a 2+magnitude quake in yellowstone is quite rare.Archive of Yellowstone Updates for 2009

    Well, from what I understand, that volcano in Alaska would be devastaing to the Northwest region and even we here in Indiana would get some fall out. Of course that's just a press release I read somewhere. it could have been wrong.

    I know it wouldn't be as big as Yellowstone, but it's still a damn big volcano and serious concern for all of us.

    Hell it might melt the polar ice caps and flood us all out! :): :rolleyes:

    (sorry, making fun of Al Gore...)

    Thanks for doing so. I had been watching but haven't in a week or so. Got caught up in my EBRD...

    Guessing she's calmed down a bit. Maybe the one in Alaska just had to belch real quick and now she's done? :dunno: Doesn't look like she's that active either anymore. Active, but not AS active.

    This is a rather important update.In the last 3 days there have been a 4.2,a 3.1 and a 3.5. Why is that important? The largest quake during the recent activity was 3.5. A 4.2 for the Yellowstone area is very unusual.Earthquake List for Map Centered at 42°N, 110°W

    Also the USGS is now totally full of sh@#

    Anyone paying even a little attention to the data ( UUSS Webicorder (Seismogram) Displays, Yellowstone Region ) can see the "swarm" has never ended and continues to become stronger.

    A question for anyone here regarding volcanic ash deposits on cropland...

    What is its pH? Wood ash is alkaline (leach lye from it), but how about volcanic ash?

    Would guess it has lots of good minerals, but what is its effect on the soil if a couple inches would be plowed under? I'm highly curious... not just for pH & minerals, but for untoward effects on earthworms too?

    Any soil specialists out there?

    Properties of volcanic ash: volcanic ash hazards and ways to minimize them
    scroll half way down to the volcanic glass section.It gives the following + more I will not post it all as it is quite long.Volcanic eruptions inject water vapour (H2O), carbon dioxide (CO2), sulfur dioxide (SO2), hydrochloric acid (HCl), hydrofluoric acid (HF) and ash into the atmosphere. HCl and HF will dissolve in water and fall as acid rain whereas most SO2 is slowly converted to sulphuric acid (H2SO4) aerosols. Ash particles may absorb these aerosol droplets onto their surfaces. When ash falls to the ground, the soluble components (leachates) can by washed away by water, potentially resulting in changes to local water chemistry and hence quality. Chemical changes in the underlying soil can occur as a result of leaching of the aerosols coating individual grains and longer term from unstable glass particles (Cronin and others, 1996). Figure 3.3 from Johnston, 1997.
