In any case, I'm in NV. I wonder if I should be concerned. 240 cubic miles. That number is unfathomable. In any case, I hope it's just doom porn. I like a global safe space.

The VEI 8 eruption with the greatest volume of ejecta known is the Wah Wah Springs eruption that occurred in what is now the state of Utah, about 30 million years ago. It is estimated to have produced over 5500 cubic kilometers of ejecta in about a week.
I didn't know fissures opening up near Yellowstone was a natural occurrence.
Rockfall is a common occurrence in the Teton Range, and is a part of the naturally dynamic environment of mountains. As a relatively young mountain range, the Tetons are still rising and actively eroding. Over long periods of time, water flowing through minute fractures decomposes rock in a process called weathering.
Once a rock has been weathered, triggers such as freeze-thaw cycles, flowing water, temperature variations, vegetation growth, and other factors can cause cracks in rock to grow rapidly and possibly break free and fall.
