Great Earthquakes and the Astronomical Positions of Uranus

Abstract

THANKS to the excellent collection of uniform data of earthquakes given by Gutenberg and Richter¹, it is now easily possible to study statistically the influence of different factors on earthquakes. In the course of a study of tidal effects on earthquakes², the astronomical positions of the planets have also been taken into account and a remarkable correlation between the positions of Uranus and the moment of great earthquakes has been established for a certain period. Gutenberg and Richter's data of all earthquakes equal or greater than magnitude 7¾ have been used. The investigations will be published in detail later, but here attention is directed to the results concerning the position of Uranus.
