"....nice, but getting a tweet seconds before an earthquake doesn’t help much."

Even a few seconds can make the difference between life and death. An obvious upgrade is to have a dedicated receiver that will "trip" only on receipt of such a message, and sound a distinct alarm. Should be trivially easy to do.

I believe when they say seconds, they mean seconds....like 2 or 3, and that isn’t time to react.
