According to a story from gizmodo.com, the Yellowstone super-volcano is "more active than previously thought," which means that eruptions are more frequent -- and the next one is likely closer than previously predicted.
New research using a new high-precision argon isotope dating technique (a technology that's like getting a sharper lens on a camera) shows that what scientists thought was Yellowstone's biggest eruption -- the one that created the 2 million year old Huckleberry Ridge deposit -- was actually two eruptions 6,000 years apart.
Ultimately because two smaller eruptions occurred versus one giant one, scientists now believe that the next eruption won't wipe out half of the U.S. -- there will just be more frequent eruptions that are 12 percent less powerful than one large eruption.
