call up NOAA in the republic of boulder, give them your exact location via GPS, ask them to run a pinpoint seismologic test and get back your results on the richter scale. could cost a bunch but think how impressed your friends will be.
Measuring Vibration in Equipment
There are alot of threads on shelf material and tweeks that cut down on vibration. Is there a device that measures this vibration? I think I remember of hearing of such a tool before my audiophile days for testing crates for shipment but I cant remember what it was called. In The Complete guide to Home Audio they suggested using a stethescope. Has anyone tried this?
