As tourists stroll between Yellowstone's 300 active geysers, taking selfies in front of thousands of bubbling, boiling mud pots and hissing steam vents, they are treading on one of the planet's greatest time bombs.
The park is a supervolcano so enormous, it has puzzled geophysicists for decades, but now a research group, using seismic technology to scan its depths, have made a bombshell discovery.
Yellowstone's magma reserves are many magnitudes greater than previously thought, say scientists from the University of Utah.
Underneath the national park's attractions and walking paths is enough hot rock to fill the Grand Canyon nearly 14 times over. Most of it is in a newly discovered magma reservoir, which the scientists featured in a study published on Thursday in the journal Science.

I’m within a 500-mile radius, BTW, but would be looking forward to the soil improvement here.
;-)
I’ve worked in some very hazardous environments before and tolerate smoke from forest fires often here. Window filters, goggles, masks, etc., for exceptionally bad times.
Another plus: we usually get a winter ice buildup that’s pretty deep. Ice dunes. Volcanism in the northern hemisphere is more likely during winter. An ash fall would melt the ice and stay in the soil afterwards. Soil is now hard packed, sterile and a little too much on the alkaline side. We need ash here.
