Abstract : Local seismic monitoring was initiated in the Fairview Peak region of Nevada in July 1961, and was conducted at intervals until 21 October 1963, five days prior to SHOAL Event. Since that date, continuous measurements have been made at three seismograph stations located approximately 10 km northeast, 10 km southwest, and 3.4 km west of ground zero. Preliminary evaluation of data accumulated through November 11 indicates that the majority of these events had their epicenters in the Fairview Peak fault block; this was true also of the majority of recorded preshot events.
