Lunar earth tides and earthquakes
SUN, MOON AND EARTHQUAKES
V. G. Kolvankar
During a study conducted to find the effect of Earth tides on the occurrence of earthquakes, for small areas of high-seismicity regions, it was noticed that the Sun’s position in terms of universal time (GMT) shows links to the earthquake-lunar distance together with Sun-Earth-Moon angle. This paper provides the details of this relationship after studying earthquake data for over forty high-seismicity regions of the world. It was found that nearly 98% of the earthquakes for these different regions, examined for the period 1973-2008, show a direct relationship between the Sun’s position and the earthquake-moon distance together with the Sun-Earth-Moon angle. As the time changes from 00-24 hours, the sum of the earthquake-moon distance and the Sun-Earth-Moon angle changes through 360 0 , and plotting these two variables for different earthquakes reveals a simple 45 0 straight-line relationship between them.
