Roger-sounds exciting-sent you a separate email.
The program does not make an output on my Windows 2000 computer.....Do smaller quakes (say, M5.5-6.5) trigger larger ones (say, over 6.5...)? I suppose the way your program is set up you can only ask for mainshocks >5.5 and FFAs >6.5-which means some of the output will be larger quakes triggering smaller one....so you may want to allow for a range of Magnitude rather than just a minimum.....Chris
