> Use the formula y[n] = c0*x[n] + c1*x[n-1] + c2*y[n-1] (from Press)

Thanks.  I'm not sure where to start to find useful values for the
constants, though.  Perhaps I should log raw data for a while and wait
for quakes which I should be able to detect, and then try different
combinations to see what makes local noise weaker while preserving the
quake signature.

My plots at (latest 24 hours)
currently show several spikes, all of which were caused by me staying
in the room.  I can easily play with some simple filters to surpress
these, but I can't yet know whether that will also kill interesting
seismic signals.

I plan to publish my code when I have something that seems to work
