Don....without aftershocks was good...so all set. But, I am curious about various things, but only check if you are curious also: like, how many M6 earthquakes are there on average/yr (I saw a list of this at NEIC once but did not find it yesterday), and does that number include aftershocks. I guessed 200 because for each decrease in magnitude of 1 I thought, but could be wrong, that there are 10x more quake...but this may include aftershocks?

So, my guess is that I was wrong and your list was OK, .....but I would not be sure of that...Chris
