don't forget, folks: the problem is all of Assumption Parish,
and that silly sinkhole and cavern are just a small part of it.
the problem is that there is a high pressure gas deposit deep down
in the crust strata that is leaking massive amount of
gas upwards to the surface. and, of course some of it
has collected in the sinkhole cavern; but, more importantly,
all of the ground in all of Assumption Parish is rapidly
becoming saturated with this gas, and soon will have nowhere
left to go except into the atmosphere....

and, my other posts talk about how far the "ground saturation"
might end up extending to...
