A team of geologists at the US Geological Survey, working with a trio of colleagues from Oregon State University, and another from the University of Wisconsin-Madison, has found evidence of rhyolitic volcanism in Yellowstone caldera shifting northeast.

Large explosive eruptions occur in Yellowstone around once every 700,000 years, according to the U.S. Geological Survey.

Volcanic activity bubbling away beneath the Yellowstone National Park in the US appears to be on the move. New research shows that the reservoirs of magma that fuel the supervolcano's wild outbursts seem to be shifting to the northeast of the Yellowstone Caldera.
