“Some of Yellowstone’s geysers have been more active lately reigniting fears that the massive supervolcano will erupt. The sudden bursts of steaming hot water highlight the dramatic nature of Yellowstone while reminding us we are all at the caldera’s mercy.” . . . (more)
“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”
“The world’s largest active geyser has erupted three times in the past six weeks at Yellowstone National Park, including once this week, in a pattern that is unusual but not at all indicative of a more destructive volcanic eruption brewing beneath Wyoming, geologists said on Saturday.”
“New images prove that the Yellowstone hotspot is powered by superheated magma rising up from Earth’s core. The last Yellowstone supereruption occurred roughly 640,000 years ago, creating the massive, 40-mile wide Yellowstone caldera and producing an umbrella-shaped ash cloud that blanketed areas as far away as modern-day New York with several millimeters of ash. The prospect of another cataclysmic supereruption has sent scientists on a decades-long search for the source of Yellowstone’s devastating power.” (more)
” . . . A Volcanic Vent opened beneath the Shoshone River outside the Yellowstone super volcano at the same time the US Geological Survey and Utah Seismic Center were specifically denying trouble brewing at Yellowstone as the reason for seismic data being taken offline last week.
