Hello John,

I suppose I should try to peg the dates of the north-south quakes better and come up with a background rate. I'm still trying to figure out the best way to study the seismic record. If it looks like there is something to it, then the tectonic questions would be very interesting. I'll bring it up with Roger and see what he suggests. My only other question would be if somebody else has looked at the coincidence. No sense in reiventing things. Here is another sample of the preliminary data. There is more. Needs work though.
