The two new-found events have been named the McMullen Creek eruption (occurring about 8.99 million years ago) and the Grey's Landing eruption (occurring about 8.72 million years ago), and they significantly adjust Yellowstone's long-term volcanic timeline – and appear to show that huge eruptions are now occurring way less frequently than they once did.
Scientists were able to use a combination of chemical, magnetic, and radio-isotopic analysis to link volcanic deposits across tens of thousands of square kilometres (or several thousand square miles), joining together geological records that were previously treated as separate.
In other words, what had been seen as many smaller eruptions were in fact two giant ones.
Grey's Landing would have covered an area the size of New Jersey in ultra-hot volcanic glass – somewhere in the region of 23,000 square kilometres (or 8,880 square miles). It would have vapourised anything in its path, and spewed out a cloud of fine ash across the globe.
With both newly identified events occurring during the Miocene period (23–5.3 million years ago), it raises the number of Yellowstone super-eruptions during that time to six – or one every 500,000 years, on average.
Compare that to the two super-eruptions that are thought to have happened across the same region during the last three million years, an average of one every 1.5 million

Basically it is now safe and wise to move out of Oregon and move to Idaho.
Does the phrase “Famous last words” occur to anyone else? Some day the next Extinction Event will occur. Has happened before many times and somehow life has managed to dig itself out of the rubble. Don’t wish to be around for it, but it will at least be a spectacular exit for those who are.
Alrighty then! One less thing to worry about!!
What if a chicom Rod from God hit it?
It’s a matter of perspective. One and a half million years really isn’t a long time if you’re a Mariners fan waiting for that first World Series.
The risk is decreasing.
All the Rangers are wearing masks.
And taking a knee.
And saying the name: Yogi Bear
Translation: We’re Screwed!
You know, that was my first thought, but I was just going to say, look out then!
I hope this doesn’t mean an end to the YouTube Yellowstone doomsday predictors. Many of them are quite entertaining.
Bet the British tabs are bummed.
Now I am afraid.
Whenever an “expert” says something I have to question it, and when they predict good news, I fear the future.

ChiComs are atheists so it can’t happen.
I guess that I don’t really need a second ash shovel.
Good to know.
Yeah, like Charlie.
Dems will need to come up with a new October surprise then.

West Thumb is a small caldera that formed roughly 150k years ago.
We’re not officially screwed until they say everything is okay and there’s no problem. They just made it official.
