Vulcan Tuesday


University of Utah seismologists have discovered a reservoir of hot, partly molten rock 12 to 28 miles beneath the Yellowstone supervolcano that is 4.4 times larger than the shallower, long-known magma chamber.

Yellowstone is among the world’s largest supervolcanoes, with frequent earthquakes and Earth’s most vigorous continental geothermal system.

The hot rock in the newly-discovered, deeper magma reservoir would fill the 1,000-cubic-mile Grand Canyon 11.2 times, while the previously known magma chamber would fill the Grand Canyon 2.5 times, says postdoctoral researcher Jamie Farrell, a co-author of the study published online April 23, 2015 in the journal Science.

The researchers emphasize that Yellowstone’s plumbing system is no larger – nor closer to erupting – than before, only that they now have used advanced techniques to make a complete image of the system that carries hot and partly molten rock upward from the top of the Yellowstone hotspot plume – about 40 miles beneath the surface – to the magma reservoir and the magma chamber above it.

      Getting hot here, touching 90’s by Friday, I ordered an air conditioner, the fans try but provide no cool air, just blows the hot stuff around.

      @ Sloan: 75+ minutes and my feet know it.

      That’s a total of at least 185 minutes so far this week.

        My feet!

        Forgot to mention the wildlife: a quail, a field rabbit, a small bird with interesting neck markings, several different solitary bees and a bumble bee.

    Very quiet in the Hillside Cafe this evening.

    Another roll-off tow truck dropping off a dead Subaru across the street, a busy place during the week around here.


  6. David B. Benson says:

    Feet still noticeable.

    World society collapses in 2028+-6 years. 😐

    That’s good to know. ❓
