Roger-you may have sent me a graph, but I don't think I could view it, so I made my own from the output of your program, which ran (I guess-it made some scary looking stuff on the screen).

Just for kicks, if you are into this, it might be interesting to see if M6-7 EQs can trigger large EQs-say, M6-8+. You could do it straight like that, or you could require that the following earthquake be larger than the original one...For example, the Dominican earthquake will be followed by the Hokkaido. Does that happen very often?

I know it is illogical that a M6 could trigger a M8 at 101-105 deg, but we probably don't understand this, so why not look?
