Scientists at Washington State University believe the Yellowstone "super-volcano" may be less potentially destructive than what had been suggested by previous studies, but also said it appers to be more active, according to Gizmodo.

The caldera, located in Yellowstone National Park in the northwest corner of Wyoming, has become somewhat infamous because of some forecasts that have suggested its eruption would be on a global cataclysmic scale. (Note: The National Parks Service considers that scenario less likely.)

WSU researchers haven't said such an event couldn't happen, just that the park's biggest explosion may have actually been two.

From Gizmodo:

Their new research shows that what scientists thought was Yellowstone's biggest eruption, the origin of the the 2 million year old Huckleberry Ridge deposit, was actually two eruptions 6,000 years apart from each other.

...

The result is that the first eruption that created Huckleberry Ridge was "only" 2,200 cubic kilometers, roughly 12 percent less than what geologists thought. Then a second eruption happened 6,000 years later, adding the remaining 290 cubic kilometers.

For comparison, Mount St. Helens produced 1 cubic kilometer of ash in its 1980 eruption. And the latest comparable eruption registered in the United States were the 116 cubic kilometers of ash produced by Mount Mazama in Oregon, 6,850 years ago.
