Earthquake Weather Report for April-May 2013

Updated on August 1, 2014

Has studied astrology/historical seismology since the late '70s in San Francisco. Published in the ISAR International Astrologer in 2012.


After the record low number of earthquakes of 6.0 and greater (especially those over 6.4) in the month of March of this year, I expected April to produce a larger than average number of such earthquakes. For earthquakes of 6.4 magnitude or higher, it was just one quake short of being twice the statistical average for a month (nine quakes instead of ten) based on USGS/NEIC data. However, I expected this to be the case due to a decrease in sunspot activity for April, when in fact it produced a noteworthy increase.


One of the reasons for the seismic increase in activity may be that a significantly large event is likely just over the horizon in the New Guinea area. As a matter of fact, four of the five worldwide earthquakes that occurred within the 6.5 to 7.0 magnitude range were located in the New Guinea area (the other one was the deadly 6.6 magnitude quake in China).

The first and last quake of 6.5 magnitude or greater during April 2013 were located in the New Guinea area and both fell within a couple of my windows defined by astrological aspect values. The later one also occurred almost at the peak time I gave for a possible quake in Japan.

The sizes of the quakes I expect in these two locations is an 8.2-8.7 magnitude temblor in or near New Guinea and in Japan, two possible quakes (one near Tokyo) of between 6.5 and 7.5 in magnitude. I don't know when these quakes will occur exactly, but my hunch is that it will likely occur during the next two months rather than later. A likely time candidate for such an event during this month in either or both locations would be on or about May 7th and May 26th (interestingly, the moon is at perigee on this last date). Destructive earthquakes in general are more numerous on or near each May 26th (this is also seen for the dates December 26 and February 6).

Now it is time for the monthly rundown of my astrologically determined windows for earthquake activity. For May 2013, the windows take up 12.5 out of the months 31 days or 40.3% of the month. If May turns out to be an average month, then it would be expected that two quakes of magnitude 6.5 or larger will fall within these windows. I am expecting at least three to do so. I am hoping to do better this month; last month's 2 hits out of 9 was one quake short of having average results. The results for May could look similar to February's results (when I fared much better) if, like then, there is an earthquake (expected some time soon in the New Guinea area) in the 8 or larger magnitude range. Here are the dates of the three earthquake windows with possible epicenter locations:

5/3/13 0000UTC +-51hrs: Taiwan, Costa Rica, Turkey.

5/7/13 1500UTC +-27hrs: Turkey, Japan, Italy, New Zealand, China, Haiti.

5/24/13 0000UTC +-3days: Taiwan, Ecuador, Peru, Mexico, Greece, China, Iran, Alaska.
