I hear (seriously) that they are injecting a lot of water into dry wells into the very depth of the continuing earthquake swarm. Could this water be lubricating the active Arkansas seismic activity?
Before you attack me remember that Arkansas is the only place in the easttern US that has large hot springs and diamonds.
I’m not going to attack you. I would suspect you are referring to the process called “fracking”, though there are other reasons for pumping water down. And there is no consensus at all as to how, if at all, it could affect unstable substrata.
It is known that (natural) underground water movements can radically alter geothermal fields (as in Hot Springs), and there is ample theories about how it could affect an earthquake zone, but a caldera? That is like a mix of half a dozen major geological processes lumped into one.
On a scale of one to one million, our scientific knowledge is in the low three digits for stuff like this. Anybody’s guess, and pure luck if it is right or wrong.
