Hello Don,

I tried to make sure that this was not directly related to the June 15 7.2 Mw.
After looking at the same data that you posted, it was my opinion that the aftershock sequence was over. I will go back and look at some of the other 7 Mw quakes in that area and see how long those aftershocks lasted. At least this time, it appeared to be broken up, and not connected to June 15. Also, it seems there is some validity to the idea of "echo quakes". I have seen them, but I have never really kept a record. Will keep my eye on Redding area.

Comments appreciated,
glen
