SSGEOS is short for Solar System Geometry Survey. It is a research institute that monitors geometry between celestial bodies related to seismic activity.
It was a sudden seismic increase in a relatively quiet month and a perfect example of clustering of larger earthquakes, a well-known but unexplained phenomenon in seismology. Using Solar System simulation software, it appears that six celestial bodies were engaged in three planetary conjunctions that converged into a near triangle from 22 to 25 June 2014.
In addition to the large seismic activity, a meteo-tsunami occurred in the Mediterranean that propagated from west to east from 23 to 27 June 2014 as a result of "unusual atmospheric forcing", a scientific study later revealed (pdf-copy).
Analysis of the planetary geometry that occurred from 22 to 25 June 2014 led to a research into the geometry between celestial bodies at the time of larger earthquakes. The first candidates were the largest earthquakes on record, which are the Valdivia earthquake on 22 May 1960 (Mw 9.5) and the Alaska earthquake on 28 March 1964 (Mw 9.2).
This research revealed that both great earthquakes had three planetary conjunctions associated with them whereby Mercury, Venus, Mars and one or more outer planets were involved. Later research revealed that the position of the Moon is equally significant.
Analysis of more recent great earthquakes (2004-2011) yielded similar results; the combined involvement of Mercury and Venus in a convergence of multiple planetary conjunctions appears to be key.
Here we emphasize combined and convergence, because there is a common misconception that "planetary conjunctions occur all the time" and that "there is always a conjunction that can be linked to an earthquake." The key is not any conjunction, but a tight convergence of multiple conjunctions.
In all cases presented here, there was a convergence of three planetary conjunctions that included Mercury and Venus with one or more outer planets and/or the Sun, next to one or more lunar conjunctions, also with an outer planet or the Sun.
After nine months of research, from June 2014 to April 2015, the first public forecast was posted on Facebook with a warning that 22-27 April could be critical. On 25 April a magnitude 7.8 earthquake occurred in Nepal. The next forecast focused on 28-29 May 2015 and a potential seismic event of up to magnitude 9. On 29 May a magnitude 6.8 earthquake occurred in Alaska, followed a day later by a magnitude 7.8 earthquake at the Bonin Islands, Japan, with initial estimates of magnitude 8.5.
During this research in 2014 and 2015, it became clear that the SSGEOS was in need of specific software to accurately compute any geometry between celestial bodies in the Solar System. Careful review of existing astronomy and also astrology software revealed that none met the requirements. So in February 2016 the software development project Solpage took off. Since 2017 the project includes SSGI models.
The specific geometry between celestial bodies that is associated with larger earthquakes is referred to by the SSGEOS as "critical planetary geometry" and "critical lunar geometry" if the Moon is involved. However, critical geometry does not always result in large earthquakes. Often, only a clustering of stronger tremors (M ≥ 5.6) is observed. From this we conclude that the key is the condition of Earth's crust, i.e. the amount of stress between tectonic plates and whether or not a larger fault section has reached its strain budget and is ready to slip. This would indicate a direct relationship between the build-up of stress in Earth's crust and electromagnetic charge from critical planetary geometry. We say electromagnetic charge, because often a convergence of planetary conjunctions that results in a large earthquake, does not directly include Earth.
