Don's Dinsmore CA forecast - another successful "A"
Posted by Lowell on November 23, 2001 at 19:33:53:

Another successful prediction for Don in Hollister. This time the predicted
and occurring events occurred near Hayford or Weaverville, CA.
NCSN is showing the following two events today:

01/11/23 17:01:56 40.4N 123.4W 29.0 2.3Md 57 km SW of Weaverville, CA
01/11/23 23:57:48 40.7N 123.3W 28.2 2.4Md 27 km W of Weaverville, CA

Don had expected an earthquake between Nov 20 and Nov 24 (most likely
on Nov 22) within 40 km of 40.5N 123.6W with Ml 2.4-3.6. The first
epicenter occurs at 20 km, the second at 33 km from the predicted
location. Both occur within the time window (one day off the
predicted day) and both are within the given magnitude range allowing
for a 0.1 unit possible error in given magnitude. In this sense,
the prediction is a complete success.

Probability of random success:

Since November 23, 1998 (the past 3 years - 1095 days) there have
been 26 5-day periods during which an earthquake matching Don's predicted
parameters has occurred. In the same period 219 5-day periods have
occurred, so the probability of random success given the past
3-year history is 26/219 = 0.11 or odds of success about 1 in 9.

Good going, Don, I'd have to give you an "A" on this prediction.
Keep up the good work.

Hi All. At least I get to stay dry with this forecast.
