How close is Yellowstone to erupting?

about 725,000 years
In terms of large explosions, Yellowstone has experienced three at 2.08, 1.3, and 0.631 million years ago. This comes out to an average of about 725,000 years between eruptions. That being the case, there is still about 100,000 years to go, but this is based on the average of just two numbers, which is meaningless.

When was last Yellowstone eruption?

630,000 years ago
The last supereruption (defined as an event greater than magnitude 8 on the volcano explosivity index) at Yellowstone took place 630,000 years ago. The last lava flow took place 70,000 years ago. But the relative quiescence since the last eruptions doesn’t mean the system is due for an eruption, Poland said.

When was the last time a super volcano erupted on Earth?

27,000 years ago
The most recent supervolcanic eruption on Earth occurred 27,000 years ago at Taupo located at the center of New Zealand’s north island.

Is there volcanic activity in Yellowstone?

Yellowstone, one of the world’s largest active volcanic systems, has produced several giant volcanic eruptions in the past few million years, as well as many smaller eruptions and steam explosions. Although no eruptions of lava or volcanic ash have occurred for many thousands of years, future eruptions are likely.

How will we know if Yellowstone erupts?

Most scientists think that the buildup preceding a catastrophic eruption would be detectable for weeks and perhaps months to years. As at many caldera systems around the world, small earthquakes, ground uplift and subsidence, and gas releases at Yellowstone are commonplace events and do not reflect impending eruptions.

What happen if Yellowstone erupts?

If another large, caldera-forming eruption were to occur at Yellowstone, its effects would be worldwide. Such a giant eruption would have regional effects such as falling ash and short-term (years to decades) changes to global climate.
