JTAdams from Jtadams.ca has build an interface for his geophones using Raspberry Pi and managed to record some seismic events on this. He writes:
I have always been fascinated with how seismic detection can see what is under the ground. So much so, that I decided to try it for myself. It works by generating a wave from the surface and measuring the reflections bouncing back from the layers below use something similar to a microphone, called a geophone. I created some amplifiers to amplify the signals from the geophones, and read them with a raspberry PI. I will show how I did all this, and what the results were.
