Hey Don:

Sounds like a few predictions there...one ring is close to Parkfield.

Yes...I wouldn't put too much into reading tea leaves.

Anyway, here's some (center) coordinates from one ring going through CA:

-119.142 32.247
-118.987 33.204
-118.822 34.160
-118.649 35.116
-118.467 36.070
-118.274 37.023
-118.071 37.976
-117.857 38.927

Looks like Tejon Pass is in the cross-hairs along SAJ...and Northridge too.

We'll see what shakes along these lines (give or take a buffer zone...).
