The most likely time for an earthquake of significance this month should be centered on noon, GMT on 12/25/2011. It can be as early or as late as 36 hours from that time. I estimate the magnitude should be at least 6.7, but I also feel that there is about a 40% chance of it being 7.1 or greater. Most likely places it will be felt are Sumatra, China, or Japan and I'm giving this a better than 75% chance of happening or more than twice what would be expected due to chance alone.

Here's an update on my estimate of the upcoming likely earthquake. I've checked over my data more thoroughly (expanding the years to include pre-1900 quakes) and have decided to move the most probable time of the event forward by 14.25 hours and expand the window from 3 days to 4.33 days. The new estimate is 12/26/2011 at 0215 UT, + or - 52 hours. The chance of occurrence might be a bit less due to Jupiter being in positive aspect to key planets which could funnel destructive energies away from our planet.

I have further refined the time and location for my upcoming quake prediction. It is now most likely to occur on 12/25/2011 at 3am, GMT (noon, LT, give or take 12 hours) in the Nankaido area of Japan where an estimated 8.4 magnitude earthquake occurred on 12/24/1854. There are two tight transiting aspects on the predicted date to the earlier date. Those aspects are at the top of the list for re-occurring aspects in quake charts. I'm also seeing the magnitude at this location to be at least 6.8 and the probability of it occurring here as 25% (at least 65% for anywhere in the world).
