Is Yellowstone volcano overdue another major eruption?
There are currently no indicators suggesting activity at the Yellowstone supervolcano is building up towards a super-eruption.
Evidence of past eruptions suggests Yellowstone last erupted 640,000, 1.3 million and 2.1 million years ago.
According to USGS geologist Jake Lowenstern, this suggests Yellowstone is not due another blast for tens of thousands of years.
He said: “When you see people claiming it’s overdue, usually the numbers they come up with say that the last eruption was 640,000-years ago but that it erupts every 600,000 years and therefore it is 40,000 years overdue.
“But in fact, if you average the eruption intervals, there’s 2.1 million to 1.3 million, and then there was another eruption 640,000-years ago.
“When you average those numbers, you come up with something which is over 730,000 years.
“So, in reality, even if you tried to make this argument, it wouldn’t be due for another 70,000 years or so.
