The PA underground fire is real. It has been burning for many years. And will continue to burn as long as it can pull oxygen through cracks and caves. It is a coal fire.
The guy on this site has a great thesis. But the air fuel mix needs to be correct and I don't know how probable the correct mix would be. My understanding is that they pump non-flammable nitrogen gas into Natural Gas reserves to pressurize it.
I don't expect the whole continent to explode even if it did blow. I would expect some ferocious jets of fire and hot burned out gasses to errupt. I really doubt the natural gas could displace the continent. A bomb not only requires an explosive, and oxidizer, it requires exceeding the bounds of confinement to the point of bursting the container. We have the confinement but failing to displace the billions of megatons of continental rock would only result in jets of pressurized gas. Maybe wells everywhere would start popping like corks. That would be my worst case scenario.
