” . . . But days at Yellowstone National Park have begun to resemble an episode of “When Animals Attack!” . . . Twice in three days, cow elk – females of the elk species – have attacked people at the popular national park, using strong legs and sharp hoofs to send unsuspecting humans to the hospital. . . . “
“Yellowstone’s Steamboat Geyser, the largest in the world, has now erupted eight times in less than three months, in a geological puzzle that has fascinated scientists working at the site. The last eruption on Monday lasted an amazing 30 minutes with strong water gushing, the occasional baseball-sized rock ejected up to 200 feet into the air and the loud rumbling sound similar to a volcanic eruption.”
“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)
The last massive earthquake in Yellowstone National Park claimed the lives of 28 people and created a whole new lake. An eruption of a supervolcano like the one at Yellowstone could render significant part of the US uninhabitable for years and threaten life on the whole planet. Over 200 tremors have struck the Yellowstone supervolcano
