Abstract : Earthquake data from Central California over the period January 1, 1969, to December 31, 1971, and from Western Nevada over the period August 31, 1954, to December 31, 1961, have been analyzed to investigate the hypothesis that the Earth tides may be the triggering mechanism for the occurrence of earthquakes. One method used compared the tidal components and the component rates-of-change at the time and location of actual earthquakes to those for random events uniformly generated over the same time period. A second method compared the differences in the Earth tides computed across the breadth of a fault zone at the time of actual earthquakes to the differences at the times of random events uniformly generated over the same time period. Statistical tests were performed to see if the distributions from the actual events were the same as the corresponding distributions from the randomly generated events. (Author)
