Wow, this would be an enormous find if it turned out to be a verifiable precursor to a major temblor. My question would be: How do you report it without setting off a never before seen panic in any metropolitan area.
If this can be scientifically proven over period of time, it will be huge. However, for the reasons you mentioned I don’t think it will be used often, if at all for the public. Maybe first responders, manufacturing and utilities.
