So this is the last post on the Eclipse Earthquake simulator. I have no plans to create the simulator (but before I drop the idea all together) I thought I’d use a little Psuedo science to make my own earth quake prediction for the July 22 2009 Eclipse.
*** Note 1: Updated May 07 2009 With data from 3 previous Total Solar Eclipses and 3 Earthquakes all in the same region (and same day within 6 hours) from the past 20 years. Note 2: This is a theory and I have no background in earth science or seismology. In short, I have no valid qualification to back this prediction. Update June 24 2009: But, this theory is now backed a credible scientist who does. Hans Lehner’s Earth Quake prediction***
Total Solar Eclipse Earthquake Theory
What is the relationship between an earthquake and an eclipse? One normally thinks of a solar eclipse as merely the moon blocking the light of the sun. What one misses with this concept, is that these are two celestial bodies that have a large gravitation pull on the earth. During an eclipse these two bodies combine gravitational forces in exactly one straight line. This means that the gravitational pull of the sun and the moon on the earth are combined during the eclipse.
The eclipse quake theory is as follows; When the gravitational force of the sun and moon are both pulling together they create larger than normal tidal forces. The solar tide is about one third the size of the lunar tide. When these tidal forces work together they provide a larger than normal downward push on a subducted tectonic plate. If the gravitation distortion and tidal forces pass over the joint between two tectonic plates that has not had series of recent earthquakes, the extra gravitational pull, and tidal force push is all that is needed to “pop the seam” and cause a major quake. Molten magma beneath the surface of the earth plays a role too. Because the earth rotates faster than the moon’s orbit, this magma tide as well as the ocean tide is often actually directly in front of the moon’s path. Matching eclipse data from NASA to earthquake data from the USGS demonstrates a great deal of correlative data between eclipses and an earthquakes.
July 22nd through July 30th 2009 Earth Quake Prediction
I used the theory to predict the biggest magnitude of earthquake activity, and it happens to be in Southern Japan. Japan sits on or near the junction of 4 tectonic plates

*** Note: 07/07/2009 Update: Historical data has changed my prediction to be a few hours before the total eclipse, with a window of 8 days after the eclipse.
Prediction is from July 22nd through July 30th 2009 readPage 2 – Supporting evidence to find out why ***
I predict a 6+ Magnitude Quake on July 22 2009 at 3:00PM Local Japanese time. This will be followed by two level 5+ Earthquakes and a Tsunami between 5:00PM and 7:00PM. The tsunami will start out in the pacific ocean (to the South East of Japan … Along the fault line) and hit all the islands to the south west of Japan, Indonesia and even reach Papua New Guinea. The major quakes will actually be along the fault lines in the Ocean.
Most of the quake activity will be south of Japan. Taiwan and Indonesia will probably be hit hard too.
Note: I have absolutely no credibility to do this. I’m just applying the theory that the gravitational pull of the Sun and Moon pulling together will do the following things.
1. Lift the tectonic plates
2. Cause the tide to rise more than usual
3. Cause an underground molten magma tide to dip and raise the plates following the water tide.
I placed all the time data from the Nasa eclipse site into an excel spread sheet four the four tectonic plates in the region. I assumed an hour delay for each event following the lunar eclipse, and then summed the values. I assumed that the events would last longer for the fluids, water and molten magma than for dry land. I then summed the values four all 4 plates where Japan sits.
The blue path above shows the lunar path that will achieve the full solar eclipse at around 11:30 AM to 12:30 PM. Red dots show where the solar eclipse will be full. Why is this the big one? A tsunami can occur with a level 7.0 magnitude or higher. The last two eclipse earthquakes in 2004 and 2007 have been 6.9. Japan has a violent 8.4 quake known as the “Tokai” quake that occurs on a cycle of every 150 years or so. The last one was in 1854. That means Japan has been ripe for the big one since 2004. This (July 22nd 2009) eclipse is the longest (over 6 minutes) in over a century and the moon is the closest it will be to earth in over a century. It has the greatest chance of causing a gravitational disturbance of any eclipse in the past 100 years. Page 2 – Supporting evidence
Just about every eclipse in the past 10 years in Japan has a significant earthquake associated with it. I prefer data within a few hours of the eclipse, but if I open the time window to a few days after, the correlation jumps to 85%. Only one eclipse in this region in 2003 did not have a corresponding quake during the past decade. For Japan, over the past decade or so, 6 out of 7 eclipses with corresponding earthquakes with in a few days (or hours) is a significant fact.
7 Solar Eclipses, 6 Earthquakes in 10 years
The first thing to happen on July 22nd 2009 is greatly magnified tidal forces (solar and lunar tide combined during the eclipse) pushing down on the subducted Phillipine plate. The vast volume of sea water (30% greater than normal) is pushing downward with billions upon billions of tons of pressure a few hours before the eclipse. Shortly after, as the moons orbit encroaches on the sun, the centripetal force of the earths rotation is combined with the gravitational pull of both the sun and moon. The gravitational pull and centripetal force provide an upward lift on the Eurasian plate. We now have both a lift on the upper plate and a downward force on the subducted plate. The only thing preventing an earthquake is the friction between these plates. The gravitational and tidal forces work together during the longest and closest eclipse in 100 years help to alleviate the friction and let the plates slide. When the plates slide we get the big tokai quake that’s been building for over 150 years. (This is my theory anyway…)
I think a real simulator to test the theory would be a great benefit. I think the TGEA properly applied with a physics engine could do it. Who knows what the real values are, but its a fun idea to play with.
Data Backing the Theory
We start with scientific data gathered from March 1988 where we have Earthquake with a few hours of a Total Solar Eclipse. This historical data matches nearly perfectly the exact location of my current Earthquake prediction.
As seen above a magnitude 5+ earthquake occurred 6 hours before the total solar eclipse in Japan, March 1988.
Its not just Japan that gets the quakes with a Total Solar Eclipse. China has a recent history too. There is a chance they will get a quake as well, but not as high a chance as Japan. The interesting thing to note is that there does seem to be a significant correlation between Total Solar Eclipses and Earthquakes in this region over the past decade. A magnitude 6+ earthquake occurred 6 hours before the total solar eclipse in China, October 1995. A magnitude 5+ earthquake occurred 1 hour before the total solar eclipse in China, August 2008.
