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.

If you desire to read the values of the various electronic components, you can click on the above image to enlarge it, but it will take a long time to load because it is a large image.
