Thank you for the clarification on how it works, sincerely! Is this the end of the line as far as the science/technology of early warning systems? Is "several minutes" (which is crazy impressive, I absolutely don't mean to downplay the achievement) the most warning we'll ever have?

I'm on mobile & quoting from memory but I recall there was a bit about a concussion wave that rolls out immediately prior to an earthquake that can serve as an early warning system now in Japan. I think it was about 30 seconds warning, during which time things like mass transit & electrical grids can be shut down. I understand that can be the difference between disaster or extinction, but is that as much early warning as we'll ever have? Is there more science being done on this specific seismological issue?
