It has been pointed out to me that the earthquake off the coast
of Northern California is actually a better match with Don's Petrolia
earthquake prediction which was posted on November 7. Actually the
event appears to fall about midway between these two predicted
events - maybe that will give a clue as to how Don is doing this.
I suppose this means the other event off the Coast of Oregon could
still happen? Huh Don?

Preliminary parameters of today's event are:
01/11/10 18:55:32 41.24N 126.40W 10.0 4.0M B OFF COAST OF N CALIFORNIA

Don's prediction from November 7 for Petrolia had read:

Petrolia, California Earthquake Forecast
Posted by Don In Hollister on November 07, 2001 at 09:39:38:

Magnitude: 2.5-4.0
From: 11/09/2001PDT - To: 11/13/2001PDT
Location: Petrolia, California
Lat: 40.3N - Long: 125.0W - Range: 40Km

Hi All. It sure is a great morning to make a forecast. I didn't have my usual
meal of a raw onion and garlic sandwich with a Moosehead Beer chaser. Instead I
had ham and eggs with a cup of coffee. Don't know if my system can handle that.

Looking for a 2.5 to 4.0 at 40.3N/125.0W. This is about 56 Km west of
Petrolia, California. It should occur on 11/11/2001.
The window opens on 11/09/2001 and will close on 11/13/2001. The radius is
40Km. Take Care...Don in creepy town
