Hi Don,

Your data appear to me to be even more supportive of that triggering theory than mine do.

It is not a theory which I am trying to get anyone to believe. It simply looked to me like it might explain those data.

I think that it would be difficult to argue very effectively one way or another on this. Nuclear tests probably release their energy differently than do earthquakes. They are also conducted relatively near the surface from what I understand compared with earthquakes which are at considerable depths. And many of the earthquakes which might be expected to trigger other earthquakes are out in the ocean, another factor to put into the equation.
