Idaho scientists find new seismic fault in Rockies (Wow)

If this makes the yellowstone calderra blow. Americas bread basket is gone, The ash would totally block out our Sun. crops would die, It would be the end of USA for awhile.

You dont want ANYTHING triggering the huge underground volcano that the United States sits over

There is the underground in case of volcanic activity or devastation from above.

Some theorize its underground all from Denver to Colorado Springs.

Im sure there is underground space all over the world. Best take precautions in case something happened so some humanity can survive.

In case of major earthquake crack though, I dunno, how does that effect underground? Does it all fall in or what? (shrugs)
