“The United States Geological Survey has increased the Yellowstone supervolcano threat to “high.” This is the first time that the USGS has updated its volcano threat assessments list since 2006.”
” . . . Despite the recent gradual uptick in thermal activity in the caldera directly below the supervolcano, the new USGS threat assessment is showing Yellowstone as stable, but dangerous when it does happen to erupt in the future. . . “
P. 20 – “While Yellowstone is the greatest supervolcano threat to the U.S. (and perhapsalso to all of human civilization), there are two other supervolcanoes within the contiguous 48 states. These are the Long Valley Caldera near Mammoth Lakes CA, and the Valles Caldera near Los Alamos, NM”
“I was a member of the Nasa Advisory Council on Planetary Defense which studied ways for Nasa to defend the planet from asteroids and comets,” explains Brian Wilcox of Nasa’s Jet Propulsion Laboratory (JPL) at the California Institute of Technology. “I came to the conclusion during that study that the supervolcano threat is substantially greater than the asteroid or comet threat.”
Strange Sounds – Rare thermal activity reported near Old Faithful in Yellowstone: New small geyser forms, area rises and falls around the spring
Yellowstone National Park says there is some new thermal activity near Old Faithful. The Yellowstone Volcano Observatory reports a rare eruption of Ear Spring on Geyser Hill, just across the Firehole River and within sight of Old Faithful. . .
