TABLE 1: DATES OF GEOLOGICAL DANGER (High Tidal Forces)
The most dangerous dates in the first group are all the New Moon; the most dangerous dates of the second group (Next page) are all at the Full Moon. Dangerous here is defined as the days of highest "vector sum of tidal forces" as indicated by the first number.  The asterisks are intended to reflect two things: the relative height of the high tidal force, and the length of time since the tidal force was that high.  Each of these factors determines whether a geological event will be triggered.  This Table was generated in 1985.
