I did that as a teenager and my father promptly curtailed my pusuit of amateur seismology. Our basement had a raised section due to a immovable (without blasting) rock or bedrock. I "isolated" my slab but only got about a weeks worth of comparative data before my Lehman (back then we called them "garden gate") instrument was "dismantled" by being hurled at the cinder block wall. If you are one who filters for teleseismic events, this is a waste of time. However if parking the car tilts things, you might consider it. __________________________________________________________ Public Seismic Network Mailing List (PSN-L)
