January 3, 2012 – Total Solar Eclipses and Global Earthquakes: The graph above shows Total Solar Eclipses and the number of earthquakes that occurred 10 days before (10 to 1) the exact eclipse day (0) and 10 days after (-1 to -10). The horizontal red line is an exponential best fit line, while the yellow line is a linear best fit line. Note that the number of global earthquakes was at a minimum on the exact day of the eclipse, with only two.
This analysis used the same quake file as the one used for the analysis of earthquakes versus the Sun in conjunction (zero degrees or 0*), opposition (180*) and square (either 90* or 270*). This file is 14,230 lines long and includes all tremors greater than or equal to 6.0 magnitude from 1973 to 2011. This file contained over 5,300 earthquakes.
On the surface, it’s apparent that the ten days before and after total Solar eclipses is much less significant, in terms of causing earthquakes during that time period; than the Sun and North Node angles (aspects). The highest quantity in the Solar Eclipse file is 16 at day -5 (five days after the exact eclipse). This is far less than the Sun/North Node analysis, which had daily quantities of 29 on day -1 and 55 on day -8. The waning square had 24 on day +4 (four days before exact).
I suspect that the Solar Eclipse to earthquake relationship is more complex than is presented in this graph. Some very strong Solar Eclipses are in effect for years, according to some analysts.
I will explore this relationship in additional posts in 2012.
