One of my favorite things that’s happens is when you read a sentence like “FM Radio based early earthquake detection”, immediately understand how that could work, and then wonder why you never thought of it. It feels like the real genesis of novel ideas is putting two things together that don’t seem like they go together but thinking about how they _could_.

I'll bite. Immediately understand how that could work? I don't see it -- what's the connection? Earthquakes happen when stress on a tectonic plate border exceeds (I think?) the static friction that was holding it in place. What's the leap from "pent up physical stress approaching a breaking point" to "has a measurable impact/effect on frequency modulation"?

  Two radio beacons in constant contact with one another will encode any external vibrations during transmission/reception, is my guess

    Not the way you expect... see: luminiferous aether. :)

Don't they need an extremely accurate clock though? GPSDO or even a small atomic clock. The phase/frequency differences must be tiny.
