I did not give proper credit in my analysis to the sources of data and their
work and theoretical ideas over the years.

The theory of tidal triggering of earthquakes (or at least seismic enhancement during
certain periods of the lunar cycle) has a long history. Our archives here at NGDC
have reports stretching back to the early 1900's relating tidal periods with earthquakes.
There have also been a number of scholarly papers on the subject within the past
100 years.

Nevertheless, like plate tectonics, which was suggested as soon as world maps
became available, it often takes persistence and patience to promote an idea
which may seem obvious to most, but is not at all obvious those whose opinions
drive scientific paradigms. Wegener did this in Plate Tectonics, but was only
recognized for his efforts years after his death.

Jim Berkland (referred to only as JOB in my analysis) has been at the forefront of
promoting syzygy - related seismicity for many years. It was his windows
which were used in the analysis. Whatever predictive and/or theoretical
uses this can be put to are in large part due to his persistence and patience,
often in spite hostility to these ideas from others.

I would also like to credit Mike Mills for his statistical treatment which was published
on the Syzygy websites. This work precipitated our belief that syzygy data should
be looked at more carefully in a statistical sense.

Finally, I would like to thank Roger Hunter for his professionalism in this whole
process. Roger chose to have the data tested, not to go with his instincts. And,
like a good scientist, when results were available was willing to consider changing
his mind in spite of whatever the results of that change would be.
