Rebollar Ciencias de la Tierra Moho depth seismicity Peninsular ranges Mean Moho depths along the axis of the Peninsular Ranges in northern Baja California are obtained from refracted waves ofevents in northern Baja California recorded on an array of 9 broadband seismic stations across the northern Baja CaliforniaPeninsula at about latitude 31°N. We used 35 events located with RESNOM (Red Sísmica del Noroeste de México) and RANM(Red de Acelerógrafos del Noroeste de México) local data. Focal depths range from 3 to 15 km and magnitudes from 2.1 to 3.9. A1-D velocity model (Nava and Brune, 1982) was used to calculate theoretical travel times of Pg and Pn for different Moho depths.The differences between observed and theoretical (Pg-Pn) travel times was minimized in an iterative process in order to find themost likely Moho depth along the axis of the Peninsular Ranges between latitudes 31.3° and 31.7°N. It was found that the averageMoho depth is approximately 42±3 km in the western Peninsular Ranges, diminishing to 31±3 toward the west along the PacificOcean and to 20±3 km toward the Gulf of California. 2001 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56840102 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.1 Vol.40 |
