I’d always consider the hubris element with this stuff. There was a suggestion 50 odd years ago to reduce earthquake intensity by releasing fault stress. It was specifically calculating using nukes strategically placed along San Andreas fault line. Once they figured that using the entire global stockpile would not be sufficient to potentially drop “the big one” by 1 point of seismic moment, the whole concept was quickly ignored.

We like to consider ourselves as powerful as a species but scale is a big factor with these things and very humbling when calculated
