When you fully appreciate that Yellowstone National Park is centered over one of the world's largest super volcanoes, you can't help but wonder when it might next erupt. This final installment of a USGS video series on Yellowstone touches on that question.
Now, when it comes to predicting the future, we're not so good at that. But delving into the past, that's much easier. And author Greg Breining did just that in his book, Super Volcano, the Ticking Time Bomb Beneath Yellowstone National Park. In addition to taking us along with him during a field course into Yellowstone's geology, Mr. Breining had us tag along with him to eastern Nebraska, to a spot 1,000 miles east of where the "Yellowstone hot spot" was located nearly 12 million years ago, to dramatize how incredibly powerful that hot spot can be when it blows.
In this, the third and final installment of a USGS series on Yellowstone's geothermal basement, Jake Lowenstern, the scientist-in-charge of the Yellowstone Volcano Observatory, tries to explain what is known in terms of the vigor of Yellowstone's slumbering super volcano.
