“Over the past few days there has been a significant earthquake swarm at Yellowstone,” says reader Murray Stafford.  “This morning there were over 50 earthquakes in the past 24 hours.  Now there is over 70!  If this thing blows, we are toast!”

Oops. As of Wednesday evening the count had risen to 83.

The following interactive map from the US Geological Survey (USGS) doesn’t seem to have been updated lately, because it shows only 64 earthquakes in the past several days.

    Try this:

    There doesn’t seem to be much activity, and counts vary with map scale. The majority are very low magnitude. Limited to quakes of all magnitudes during the last 24 hours yields only 16 actually in Yellowstone.

  2. Paul Hooks says:

    A good portion of Yellowstone Lake is above the Caldera, so it is possible that a moderate earthquake event could turn nasty.

  3. Steven Rowlandson says:

    One good super eruption and we will have ice age now plus a famine and survival of the fittest.
    What the hell! If it is going to happen nothing is going to stop it any way.

  4. crosspatch says:

    It is likely that we would see hundreds to thousands of years of volcanic activity prior to another caldera forming event. We would most likely see the (re)building of one or more volcanoes over some period of time.

    Just as long as it does not screw up my end of June vacation to Yellowstone, I will be happy!

    http://www.uni-koeln.de/math-nat-fak/geomet/meteo/winfos/synNNWWarctis.gif Canada is faking their temps. They have been doing this for at least 10 years. No one has picked up on this. They are posting temps 40 degrees celcius WARMER than a nearby station. And there are never any stations with bad data that is colder.

    Use this link –

    It shows the last weeks worth of activity, I believe, not the daily activity. When I just looked at it, it showed 83 quakes.

  8. Ron Greer says:

    Hekla and Katla are more likely in the near future, espeially if they go off together

    It is part of the human psychosis to always ignore the elephant in the livingroom. Obviously Yellowstone is well over due for its next big eruption. But everyone just goes about their day as if it will never happen in their lifetime. Yellowstone is right now building up to the big eruption. This swarm of earthquake activity is fresh lava rising up into the lava chamber. Inevitably the lava will burst to the surface and then literally all hell will break loose. It only takes a spark to get a fire burning. Certainly I am worried about the situation. However, nothing I might do or say will make me any more likely to be able to survive it.

    In December 2008, continuing into January 2009, more than 500 quakes were detected under the northwest end of Yellowstone Lake over a seven day span, with the largest registering a magnitude of 3.9. I followed events closely from the UK. Harmonic tremors were observed at times, indicating magma movement. The most recent swarm started in January 2010 after the Haiti earthquake and before the Chile earthquake.. again, harmonic tremors were observed. With 1620 small earthquakes between January 17, 2010 and February 1, 2010, this swarm was the second largest ever recorded in the Yellowstone Caldera. The largest of these shocks was a magnitude 3.8 on January 21, 2010. Although a super-eruption last occurred 640,000 years ago, there have also been many destructive eruptions, steam explosions and lava flows since that time.

  11. Poldar says:

    This is not unheard of but is rare for Yellowstone. Back in the mid 80’s they had a big concern when they had an outbreak of swarms with over 3,000 earthquakes in 6 months…at 83 per week they would be sitting at about 2,000 earthquakes over that same 6 months if it continues

    Well wait till the next mantle plume.. remember what formed the Deccan plateau in India some n-million years ago..I dont think humans are quite ready for what dear ‘mother earth’ can throw at us. Poor earth worshipers. Dont worry life will survive..in some form as its been doing for some 3×10^9 years.
