Hello Roger-feel like doing maps with the FFA rings for the M7.6 New Guinea quake, one with quakes for 10 days before, and one for quakes 10 days after? There have been a few quakes >M6 since, and it might be interesting to visually see how they sit relative to the rings-for example, there was just one in Hokaido and another in Kamchatka.....Chris
My old .aol address is no good anymore-better to have the maps posted so we can all look at them.
