The amplifier above consists of two 741 op-amps in a "follower-with-gain" arrangement. Capacitors on the input function to suppress high frequency signals which may represent a large component of the site-specific seismic background "noise." Use the lowest value capacitors that will suffice for your equipment and your location. This is probably a "trial-and-error" approach.
