Snoopy, I was looking at the data and noticed that as well. I also noticed that the Nevada and Andreanof Island quakes were happening regularly at very shallow or 0.0 depths.
I recall one other area had regular quakes at a 10-mile depth, but I can't remember where it was located. Isn't the bottom of the crustal layer around 10 to 12 miles down?
