On the Dependence of Earth’s Seismic Activity on Lunar Distances

In order to explore any direct link between celestial phenomena and the seismic activity the distance between Moon and the Earth is calculated at the time of all major Earthquakes during the last 109 years. It is found that the Earthquakes (EQ) frequency is very low (4.4%) for lunar distances less than 360,000 km (close to perigee). At large lunar distances greater than 400,000 km (close to apogee), the EQ frequency (27 %) is very high. A cubic relation between the two has a high degree of goodness of fit. This leads to a major revelation that for the period of study there is found a clear dependence of EQ frequency on lunar distances.
