Hi Charles and all,

ONLY on the light side....your rocking chair analogy sure brings
back the most unusal memory I have of a quake that occurred
in 1969 in the Portual-Morocco area, M7.8; that I "felt" in the
Denver, Colorado area.  I was asleep in a rocking chair, when
I had the feeling I was moving (or rocking), and rolled my head
over to check on a makeshift drum recorder I had
was synchronizing the slow movement with a hooked up seismometer
I had in operation.  For the rocking chair "seismometer"; in effect, I was
the "mass" !

I did just lay there and watched was a unforgettable

Your project meets with my rolling approval...

Take care, Meredith
