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 study into the geometry between celestial bodies at the time of larger earthquakes. The first candidates that were selected are 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 study revealed that both great earthquakes occurred after a near convergence of three planetary conjunctions whereby Mercury, Venus, Mars and one or more outer planets were involved. Later studies revealed that the position of the Moon is equally significant.
Analysis of more recent great earthquakes (2004-2011) yielded similar results, whereby the simultaneous involvement of Mercury and Venus in a convergence of multiple planetary conjunctions appears to be key.
Here we emphasize simultaneous 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, Ditrianum's first experimental 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.
Today, the SSGEOS uses dedicated software to compute and map specific geometry between the planets, the Moon and the Sun. This geometry is visualized with different SSGI models. The software is used for both earthquake forecasts and reports.
