Earthquakes have existed throughout history, and some 139 strongest earthquakes along the San Andreas Fault in California, from 1812 to 2004 have been examined for potential correlations. Calculations show that solar gravitational force is 176.1 times stronger that due to the moon. The total geometry has been greatly simplified by projection onto the ecliptic plane: the sun, the moon, and earthquake locations for ease in computer processing; so decimal units have been incorporated to enter the day of the year, the time/location of the earthquake, and the phase of the moon, and its liocation relative to the moon, to enable computer processing all of these parameters. California Earthquakes cannot be prediceted but a probability exists.
