Horrible Today: Yellowstone Volcano Powerful Erupts Rocks World! Dark Skies Cover by Volcanic Ash. Despite widespread fears of a catastrophic “supervolcano” eruption, scientists at the Yellowstone Volcano Observatory (YVO) have speculated that such an event would likely look much different than the scenario many have envisioned. Mark Stelten, deputy scientist in charge at YVO, explains that while the idea of ​​a “megavolcano”—one that would spew massive amounts of ash and lava across the country and beyond—is often overblown, such events are extremely rare. Yellowstone’s last supervolcano erupted about 640,000 years ago, and the likelihood of another eruption in the near future is extremely low. What might happen if Yellowstone were to erupt is hard to predict with certainty, though Stelten offers some insight into some of the more plausible scenarios. A smaller eruption, which is much more likely than a supervolcano, would likely produce a lava flow or dome, which, while dramatic, would be less destructive and pose less of a threat to humans.
