While Casper and other cities along the path of the solar eclipse this summer prepare for an influx of tourists and scientists, one woman in Wyoming is worried.

Darrah Perez of Riverton is a believer in signs and portents, and has, she said, had a revelation. The total eclipse of the sun, which will pass over the United States on August 21st, will trigger the eruption of the Yellowstone Caldera, sometimes known as the supervolcano.

The caldera measures 35/45 miles and is full of pressurized, molten lava. The Yellowstone Supervolcano is the volcanic field which produced the latest three supereruptions from the Yellowstone hotspot; it also produced one additional smaller eruption, thereby creating West Thumb Lake 174,000 years ago. The three super eruptions occurred 2.1 million, 1.3 million, and approximately 630,000 years ago.

Experts say the ash cloud from a full-bore eruption would blanket most of the United States with devastating results.

But, scientists say the chances of this are remote for the foreseeable future.

Darrah explains in the interview the confluence of numbers and other influences that led her to her conclusion.

Give it a listen and judge for yourselves.
