Hi Jon,
       
       I would use a mastic adhesive called BluTack or WhiteTack. It is a 
putty like adhesive material which never sets hard. I buy it from stationery and 
hardware suppliers. 
       An alternative method would be to drill holes on the floor and fit 
rawlbolts and a metal strap over the top of the seismometer case.

       Regards,
