    Over 400 quakes in Yellowstone in the last week or so. USGS states some quite deep, down near the magma chamber. Not exactly what we need at the moment. Should Yellowstone go, it would probably have a negative affect on our economy:(

    Isn't there a super volcano under Yellowstone, or am I thinking of somewhere else?

    yes there is, i think that is what old faithful is part of not sure how it all works though. If yellowstone goes my brother is screwed he is near the east end. I went through Yellowstone in a couple times, kind of boring since the fire went through it! They did have a medium size one when my brothers were little and my mom lived in a place called Recluse Wyomning but there is nothing around there to do much damage structurally!

    It will have a negative impact on our economy, but Bush will be blamed which makes it okay.

    I was at Yellowstone before they had fences around the geysers (60s). Kids would just run for a geyser and jump in. We called these kids 'Stu'.

    Hopefully that's not your only concern regarding Yellowstone. It's a great nationally protected resource for the U.S. Well worth a visit as others said.

    As for the earthquakes according to the USGS site seismic activity has decreased significantly since yesterday. I guess the recent 900 earthquakes are well above typical activity, but not unprecedented for the park according to the site due to the park being near two fault lines.

    yes there is a supervolcano under yellowstone...it is not like mtn st helen however...friend out there have mentioned the increase in quakes and the changing level of lakes there for nearly a decade....if it goes..it will not impact the economy it will destroy entire states...


    Yellowstone National Park sits atop a subterranean chamber of molten rock and gasses so vast that the region, known for its geysers and grizzlies, is arguably one of the largest active volcanoes in the world.

    Granted, it's not your typical volcano, either in scale (it's huge), appearance (it's a vast depression, not a single mountain) or frequency of eruption (at least hundreds of thousands of years apart).

    But it is active, and the evidence is everywhere.

    A relatively close-to-the-surface magma chamber — as close as 5 miles underground in some spots — fuels thousands of spewing geysers, hissing steam vents, gurgling mud pots and steaming hot springs that help make Yellowstone such an otherworldly and popular tourist attraction, with 3 million summer visitors.

    Molten rock and gas in a chamber near the Earth's surface is similarly present below "traditional" cone-shaped active volcanoes, like Mount St. Helens in Washington state.

    But there are differences. Huge differences.

    The crater atop Mount St. Helens is about 2 square miles. The Yellowstone "caldera" — a depression in the Earth equivalent to a crater top — is some 1,500 square miles.

    The 1980 Mount St. Helens eruption blew 1,300 vertical feet off the mountain, sent an eruption column 80,000 feet high in 15 minutes, ejected 1.4 billion cubic yards of ash detectable over 22,000 square miles, and killed 57 people.

    But the last major eruption at Yellowstone, some 640,000 years ago, ejected 8,000 times the ash and lava of Mount St. Helens.

    And that wasn't even the largest eruption in Yellowstone's prehistoric past.

    "Yellowstone is much larger than any other volcanic feature in North America," says geophysicist Bob Smith of the Yellowstone Volcano Observatory and the University of Utah. "People don't realize this."

    Yeap lets just hope its just letting off steam and not the big one.

    It wont matter much , if its the big one we wont have anything to worry about ever again.

    QT Yellowstone Caldera (the eruptions of which can be violent enough to send a layer of ash 6 feet deep as far away as Chicago and which erupts every 600,000 or so years and last erupted 640,000 years ago) Update:

    There were 34 earthquakes at Yellowstone in October.

    There were 69 earthquakes in November.

    There were 11 earthquakes the first three days of December.

    The rise of magma beneath the ground continues at a record rate.

    Ho, Ho, Ho!
