Don,

I don't think the oinkers will be messing with the creepmeters as much as they
would with seismometers and even the dilatometers etc. Plus, most of those
instruments output (as we see it) is filtered to remove and short period garbage
that things like piggies rooting about or human jerks jumping up and down
might cause.

Part of the "detrending process" although from time to time stuff does leak through
the algorithms doing the crunching.
