The seismograph is a Raspberry Pi connected to a SM-24 vertical geophone. The geophone has a 10 Hz response, and is sampled at 128 samples per second (SPS) via an ADS1115 ADC, with 16 bit resolution.

In the future, this may be replaced by an ADS1232 24 bit ADC, with 80 SPS.

A leyman, long period sensor might be more interesting.
