Yellowstone's supervolcano hasn’t seen an active eruption in 664,000 years.And before that, the volcano last erupted two million and 1.3 million years ago - meaning an eruption has taken place after a 600,000 to 700,000 year gap - sparking fears among some the volcano is due one any time soon.However, Ben Andrews, the director of the Smithsonian's Global Volcanism Program told National Geographic: “I want to emphasize this in bold, underlined, blinking text: We are in no way overdue for an eruption in Yellowstone.”, Read More: Yellowstone volcano SHOCK: Scientists explain added geyser activity. The last time prior to 2014 that Steamboat had a major eruption was in July 2013. The Yellowstone supervolcano’s last catastrophic eruption, about 630,000 years ago, was not a single event, but two powerful and closely-spaced eruptions, according to a new study. The Yellowstone Caldera is a Supervolcano and caldera located in Yellowstone National Park in Wyoming, United States. It has been 70,000 years since Yellowstone last erupted. The last supervolcano eruption happened in Indonesia 74,000 years … What type of eruption will Yellowstone have if it erupts again? In their observations the USGS noted: “In the past week, there have been changes afoot to the thermal features on Geyser Hill in Yellowstone's Upper Geyser Basin. The USGS says the odds of Yellowstone erupting are 0.00014 percent — lower than the odds of getting hit by a civilisation-destroying asteroid. A large and diversified group of earth scientists and accompanying family members participated in this 3 1/2-day field trip that focused on water/rock interactions over widely ranging... Public Lecture on Yellowstone Volcano by Jake Lowenstern at Menlo Park, CA on January 23, 2014. When was the last time Yellowstone erupted? The Yellowstone Volcano: Past, Present and Future, Yellowstone Volcano Observatory (Part 2 of 3), Yes!

Its submarine flanks descend to the sea floor an additional 5 km (3 mi), and the sea floor in turn is depressed by Mauna Loa's great mass another 8 km (5 mi).

The earlier Island Park Caldera is much larger … The last time Steamboat erupted three times in one year was 2003. These breakouts were active just a few hundred meters east of the County lava viewing area. “The eruption ejected not only rocks, but also material that had fallen or been thrown into the geyser in years past, like coins, old cans, and other human debris.”. Rock deformation has already occurred that dwarfs that of Mt. Why is this Yellowstone swarm so interesting? The last time the Yellowstone volcano erupted was around 640,000 years ago. This field-trip guide was originally prepared for the 7th International Symposium on Water/Rock Interaction (WRI-7) held in July 1992 in Park City, Utah.
