Many experts are of the opinion that the Yellowstone volcano will explode earlier than expected.
Recent research suggests that a super-eruption will occur for decades, not centuries, as previously thought. Scientists say that a super eruption will cover most of the US with a thick layer of ash, plunging the earth into a volcanic ice age.
Many of the best researchers who closely follow the caldera are concerned about the increasing seismic activity in the volcano area. Seismologists from the University of Utah work closely with geologists in Yellowstone, tracking these changes.
Journalists and scientists went to Yellowstone to check whether the volcano really wakes up.
