(N.Morgan) An very interesting study from the University of Utah that the hot, molten rock beneath Yellowstone is 2 ½ times larger than previously estimated, meaning the park’s supervolcano has the potential to erupt with a force about 2,000 times the size of Mount St. Helens. The chamber is 18 miles wide and runs at depths from 3 to 9 miles below the earth, he added. That means there is enough volcanic material below the surface to match the largest of the supervolcano’s three eruptions over the last 2.1 million years, Farrell said. The largest blast — the volcano’s first — was 2,000 times the size of the 1980 eruption of Mount St. Helens in Washington state. The USGS’ Yellowstone Volcano Observatory listed the park’s volcano alert level as “normal” for December.
Some scientists tracking earthquake swarms under Yellowstone have warned the caldera is overdue to erupt. Farrell dismissed that notion, saying there isn’t enough data to estimate the timing of the next eruption. “We do believe there will be another eruption, we just don’t know when.” A large earthquake at Yellowstone is much more likely than a volcano eruption, Farrell added. The 7.5-magnitude Hebgen Lake earthquake killed 28 people there in 1959. Some 640,000 years ago there was a colossal cauldron of magma, a supervolcano, that exploded with such violence that it left an ash layer almost ten feet deep a thousand miles away in eastern Nebraska killing all plant life and covering almost all of the United States west of the Mississippi. Modern geological surveys have shown that this supervolcano erupts catastrophically every 600,000 years. The land that supervolcano is trapped in was called by Blackfoot Indians ‘the land of evil spirits’ -what we know today as Yellowstone National Park.
