Roger-probably a cumulative plot. But, if not too difficult, it would be good to have a list like you had for FFAs-for each flare on the list and the M5s that follow within, say, 10 days, with date/time lat/long magnitude as before. That way one of us can evaluate whether any peaks we see are from a single quake and many aftershocks, or if it is from quakes in different areas. We can also look and see what tectonic environment from the Lat-Long

Again, I don't have any plans to do anything with your hard work/Lowell's ideas, but have been curious enough about this for long enough that I'll spend the time to go over your results...Chris
