Paul,

Generally, earthquake tables are violent things.  I doubt that any portable
earthquake table would give the powerful experience that you would probably
like.  Strong accelerations are involved, and these require very secure
anchorage to a building structure. Conceivably, you could build up enough
weight (?with water tanks?) to anchor one, but I don't believe that this
has been done, and there could be floor load problems.  Our experience at
The Tech confirmed these points, and tallied with others' experiences.

I hope you get  helpful answers from the listserv, but if you don't,  these
are probably the reasons.

Good luck!  Peter Anderson
