Solar System Geometry Index (SSGI)
updated May 2020
The Solar System Geomtry Index (SSGI) is the computation of a dataset based on values given to specific geometric positions of the planets, the Moon and the Sun within a specific time-frame. A convergence of critical geometry is depicted by the SSGI graph as a higher peak, which may indicate upcoming larger seismic activity, usually within three-four days from the moment of that peak.

After several years of observation and research, it became clear that some planetary and lunar geometry in the Solar System clearly tends to cause a seismic increase, while other geometry does not. From these observations a model was derived and added as an algorithm to the software program Solpage.
Development of the SSGI started in July 2017. A basic algorithm was completed within two weeks. Since then, it has been revised and extended several times. The algorithm has been tested on large earthquakes in the past and shows obvious peaks — often a convergence of planetary (PG) and lunar (LG) peaks — near the time that a large earthquake occurred.
SSGI interface in Solpage
There are currently three SSGI models in use: 1.'COMMON' emphasizes interpreted critical planetary and lunar geometry based on long-time observations. 2.'SUM' displays a categorized sum of basic critical geometry between the planets. 3.'DETAILED' shows the basic critical geometry of each planet, the Sun and the Moon.
As of August 2021, with version 7.4 of Solpage, the COMMON SSGI graph has been revised. Instead of red peaks for all critical planetary geometry (PG), different colors are now used to mark geometry involving Mercury (PGme), Venus (PGve) and other planets (PG). Visualization of the involvement of Mercury and Venus is important, as convergence of critical planetary geometry with these two planets account for most of the major earthquakes. This conclusion is based on nine years of research.
In the course of 2022 critical geometry has been categorized into conjunctions (c), right-angles (r) and semi-right angles (s) (SSGI version 7.8.2.317). Extensive research has shown that this geometry, in particualar with Mercury, Venus and the Moon, has a strong relationship with stronger (Mw ≥ 5.6) earthquakes and with their tendency to cluster.
