Very cool machine, but it seems to only have one degree of freedom. I would have thought that the vertical movement was pretty significant as well. Building a machine to wiggle a building sized object up and down would be pretty damn hard I imagine, though.

buildings are designed and built to support the vertical loadn, with plenty of safety margin. I think any failure mode in an earthquake is going to come from horizontal movements.
