Abstract
A permanent seismographic array has been established around the Gulf of California. Solar-powered stations are operating at Caborca, Bahia de los Angeles, Guaymas, Topolobampo and La Paz. Trailer stations using local 60-cycle power are operating at San Felipe, Rio Hardy, Rancho Meling, and Ensenada. The array is unique in the following aspects: (1) It is the only array operating in close proximity to an active region of sea-floor spreading; (2) its sophisticated low-power design and use of solar energy made siting choices simpler so that local noise sources could be minimized; (3) it is the first accurately timed array to operate in northwest Mexico. The array has already provided important information on seismicity in the Gulf of California and has aided in several sonobuoy studies of swarms and aftershock sequences. As more data accumulate, many of the important questions concerning the seismicity, tectonics, and structure of the Gulf of California will be answered.

The authors would like to thank Mr. Nat Motta for working design and construction of electronic equipment for the stations; the Cal Tech shop members for fabrication of the housing, Mr. Ralph Gilman for assemblage of the stations and installation and checkout operations on site; and Mr. Miguel Farfán for assistance in making local arrangements, installation and maintenance. Several, students aided in installation of the array, including Alejandro Nava. Personnel from CICESE have been responsible for upkeep of the stations since 1973, including Juan A. Madrid, Javier Rebollar, Luis Munguia and Miguel Farfán. Local persons too many to mention helped greatly at each of the stations. The installation of this array was supported by the National Science Foundation under Grants NSF GA 27115, UCSD; NSF-GA-21397, Cal Tech; and UNAM intramural funds. The Mexican Federal Power Commission (CFE), supported the array through assistance of local personnel, providing of station sites and logistic support. Thanks are due the National Research Council of Mexico (Consejo Nacional de Ciencia y Technologia, CONACYT) for support of Mexican research personnel at UCSD through scholarships, for the creation of funding of CICESE as a supporting academic institution of the geophysical effort in Baja California, and for the successful coordination of this international research program since 1971. NOAA supported the project through the advice and suggestions of James Jordon and Leonard Murphy as well as temporary loan of some equipment. NASA has recently provided funds for replacement and upgrading equipment under NASA NGR 05-009-246. | ||||||||||||||
