On December 1, 1959, Stanford Research Institute SRI undertook Project San Andreas, designed to investigate and measure aftershocks of earthquakes in the coast ranges of California within 150 miles of San Francisco or at greater distances from San Francisco if the magnitude and character of the earthquake are of sufficient interest to warrant investigation. The purpose of this research is to determine whether there is any significant difference between the seismic disturbances and terrain effects which follow an underground explosion and those which follow an earthquake. The study of the frequency of occurrence and character of aftershocks originating from both types of disturbances will help establish to what extent sesmological monitoring can be used to detect any possible violation of an international agreement to ban nuclear tests.
