In northern Baja California, the two largest regions with different geological characteristics are the granitic Peninsular Ranges of Baja California (PRBC) and the sedimentary environment of the Mexicali Valley (Lomnitz et al., 1970). The boundary of these two regions is the Main Gulf Escarpment (Fig. 1). The northern Baja California peninsula has active normal and strike‐slip faults originating from the transtensional limit between the Pacific and North America plates (Stock et al., 1991).

Additional Information:© 2015 by the Seismological Society of America. Published Online 5 November 2014. This project was the first of a bigger project designed to improve the estimation of the crustal model for the northern region of Baja California. The Mexican National Council Science and Technology (Consejo Nacional de Ciencia y Tecnología [CONACYT], in Spanish) provided financial support for this project (CB-2009-133019 SEP-CONACYT). J. Stock’s participation was supported by National Science Foundation (NSF) Grant OCE-0742253. This work was performed using the facilities of Centro de Investigación Científica y de Educación Superior de Ensenada (CICESE). José Acosta provided us the 2 Hz seismic stations deployed to record the explosion, and Gustavo Arellano and Euclides Ruíz provided the technical support for the SARA (; last accessed October 2014) instrumentation. We acknowledge Luis Orozco, Oscar Gálvez, Francisco Méndez, Francisco Farfán, and Orlando Granados for their help in the installation of the instrumentation along the profile. Sergio Arregui provided the main script that we used for generating the maps using the Generic Mapping Tools (, last accessed October 2014; Wessel and Smith, 2009) software. We thank the RESNOM staff for the assistance in data accessibility (wave forms and location files) of the earthquakes used in this work. The comments and suggestions provided by Editor-in-Chief Zhigang Peng, Walter D. Mooney, and an anonymous reviewer substantially improved the content of this paper.
