Seismographs have picked up a swarm of earthquakes in the northwestern corner of Yellowstone National Park, including dozens early Tuesday.

The University of Utah Seismograph Station reported five small earthquakes including those with magnitudes of 3.4, 2.7 and 3.2 in a 20-minute period starting at 3:33 a.m. in an area 16 to 18 miles south of Gardiner.

Earthquake information specialist Paul Roberson said there were another 20 to 30 small quakes Tuesday morning that hadn't yet been posted on the university's website. He called it a fairly normal swarm for Yellowstone. He didn't expect there to be any damage.

Seismographs recorded 31 quakes in the same area south of Gardiner on Saturday, while another 23 were reported last Wednesday and Thursday in an area between 18 and 19 miles east-southeast of West Yellowstone.

    Reporting on a swarm of earthquakes in Yellowstone, isn't that like saying the wind will blow tomorrow? Maybe it's a form of advertizement "Come see Yellowstone, it shakes"
    As far as the end of the world, won't come soon enough for me, but I'm old. I know how messed up we are getting.

    Again, I say lets go for renewable energy ( like nuclear plants that will make Wyoming a radioactive capital when the rods blow and we cant dispose of them because ( other space is to expensive and has not been addressed . or better yet lets sell then to the kids of china. Lets sell our wind to California or Arizona, kill our birds of prey and owls and bats, so they can keep the lights on at triple the rates. Ya we got a system going on here in the usa. and I for one do not see democrat or republic doing much but lip service.

    It would be a very rare day that a quake did NOT occur in Yellowstone.

    The magma chamber was once under Idaho, but shifting technical plates place it under Mountains in Wyoming. As the plates march on, the magma chamber will be under the hydrocarbon rich big horn Basin -- quite a combination. Ash over everything is the least of our worries.

    If the super-volcano under Yellowstone blows, we're all toast.

    Is it known by any here? What is considered a normal amount of quakes in a so called swarm? The writer did crappy research in writing this story....

    This article has a lot of good information on this subject:


    From what I can tell, the number of quakes in the Yellowstone area have been gradually increasing for years, but no one really knows if that means anything, because the Yellowstone caldera is unique. Apparently it has erupted three times in the past, the eruptions being roughly 700,000 years apart. The last eruption was about 640,000 years ago, so it could erupt at any moment. Or not for tens of thousands of years. Or never.

    The general rule with volcanoes is more quakes = eruption coming soon. But Yellowstone isn't a normal volcano, so no one knows what the increased frequency of quakes means.

    Recent studies show the Yellowstone magma chamber to be much larger than expected, which means everyone knows much less about it than expected.

    So it's anyone's guess as to what is happening, as far as I can tell.

    A little context would be helpful. What is the normal frequency of earthquakes in this area? Is the magnitude of these quakes typical or not? And what is the normal migratory pattern for bison?

    Liberals instead of putting their money in to climate change should now start sticking money in Old Faithful, if that Caldera blows we will have 20 feet of molten ash over most of the Country and the Northern Hemisphere.
