Maybe GOCE also has the NK "earthquake" information.

It...would never have occurred to me that earthquakes could register at an atmospheric level based on sound alone.

It's not "sound", rather pressure changes that can be recorded at frequencies that are inaudible. No different than a strong wind.

This particular satellite orbits rather low .

AKA, "sound" ;-)

Sound means audible, infrasonic means "below the range of sound" :)

No, it doesn't.

You may just want to drop this one.
