On the possible connection of lunar-solar gravity variations with earthquakes

Abstract

The possible correlation of earthquakes of magnitude M=6–7 and lunar-solar variations of gravity for the period from 1986 to 1997 is analyzed. This article is a continuation of the studies conducted earlier by the author [1] on a more extensive factual material. Earthquakes are grouped near extremes of variation in lunar-solar variations: most events are associated with the maximum gradient of variation. Maximum and minimum values of gravity variations cause the least deformation in the earth's crust. The impact of lunar-solar attraction on the earth's crust and the Earth as a whole is enhanced by external space factors, which increases the probability of earthquakes.
