The sounds are played back at 250x real time to bring the inaudible, infrasonic earthquake signals into the audible range.

How did he do that?

read how a microphone works
it's just moving the frequencies from very low into the audible region

so say it's some shit at < 20 hz, using some tricks with fourier transforms n shit you can hear it
samplers for making music work the same
you know, how you can record in your voice and then press keys on a keyboard and it changes the pitch but the length of the sample stays the same

it gets complicated to do it well in realtime and not sound like shit
