you might find that, with a large event nearby, your system will 
saturate - the signal level will be too great for your A/D.  If you have 
a spare channel on your filter/amplifier you might want to connect your 
geophone to 2 channels, the second one having a lower gain in the hope 
that it will not saturate.
