dc.description.abstract | The seismic activity of the Mexican Pacific margin is principally due to the subduction process of the Rivera plate beneath the North America plate and Jalisco Block. In 2014, the TSUJAL geophysical experiment provided new data to archive a better knowledge about the crustal structure and their implications in seismic and tsunamigenic potential hazards. In this study, we present the processed and analyzed bathymetric, WAS and MCS data along the TS11 seismic transect (115 km length) across the southern of Islas Marías. The seismic sources used in this work correspond to the airgun shots provided by RRS James Cook every 120 s and 50 m to recover WAS and MCS data, respectively. These sources were registered by a network of 4 OBS and 30 land seismic stations and the MCS data were acquired with a 5.85 km length streamer with a 468 active channels. Meanwhile, the bathymetric data were obtained with 2 multibeam echo sounders, EM120 and EM710, obtaining a 75 – 80 m of grid resolution. After data processing and interpretation, we have obtained information about two basins (De la Cruz Basin and Tres Marias basin) delimitated with geological lineaments alongside the Sierra de Cleofas from bathymetry, being Tres Marias basin the deepest zone in the area. Moreover, the main canyon founded in this study (De la Cruz Canyon) has been classified as type 3, according to Harris & Whiteway (2011). From seismic data, we have determined the shallow and deep crustal structure of the northern part of Rivera plate subduction with a dip angle between 6° and 8°. In this region, the oceanic crust is 10 km deep, increasing up to 20 km, while the deepest layers of the upper mantle have been determined at 45-50 km | - |
