Below Is A WMV Video file Compacted as a RAR file.

It shows the potential for seismic detection use.

I think it would take Industrial R&D to make it work.

Not sure what kind if sensor for detecting the relative motion.

Small damping in the horizontal plane.

With very careful design, lower periods may be possible.
