Ian,

A couple of years ago, I raised the question concerning tilt.  At that time
I had a vertical pendulum which had a natural frequency of about 1 second.
I was most surpised when one of the earthquakes in the Aleutians showed up
very clearly with a 15 second period in California.  I
believe that it was recording tilt.  I would recommend you trying to
duplicate.
