Hi Don:

Thanks for the correction. I knew it was 32 something.... So much for the 'hand grenades and horseshoes' memory huh ? :-)

Looks like the line comes in offshore going through Petrolia, N. CA on over to Klamath Falls area in Oregon. There's already been activity at Petrolia prior to this M7.3 so maybe they'll get another 3+ pointer over there if this FFA ring pans out.

The area of the world covered by all the FFA rings is about 12-13 percent. So the odds of randomly chosing any location in the world which will land on an FFA ring is about 1/12 or about 8.3 %.

Should be interesting to see if anythings 'a movin' around the locations above.

Take care - $.02
