Hi Dave.

I did recently did put my geophone underground, so far everything is
working well. You cannot get rid of the wind noise, since the ground
vibrates as the wind goes over it. You can see pictures of how I put my
geophone underground here, http://www.jonfr.com/myndir/v/eq/geophone/

My geophone is ~80 cm underground and in a waterproof bucket (far as I
can tell, the waterproof appears to work, until proved otherwise). I did
just use a 20 mm plastic pipe and I did seal the other end, I did use 8
meters of the pipe. Since I was not able to put my geophone at more
distance from my apartment.

Regards.
