In this work, we present the preliminary results about bathymetric, structural geology, and wide-angle seismic data of the southern coast of Bah{\'\i}a de Banderas. These data indicate the slab thickness in this area is about 10 km and presents a dip angle of about 8. Continental crustal thickness below Puerto Vallarta is about 20 km, but no evidences of continental Moho and clear subduction features (trench, accretionary prism) are observed. Nevertheless, this model supports the hypothesis that the region of Bah{\'\i}a de Banderas is under strong crustal stresses generating structural lineaments with the same trends offshore and inland due to the convergence of the RP against the JB. Most of the seismicity reported can be associated with the main structural lineaments. Moreover, the Banderas Canyon (BC) is apparently in an eastward opening process, which seems to continue through the Rio Pitillal river valley; no seismic or morphological evidences were found to suggest the BC is a continuation of the Vallarta graben. Offshore, the Sierra de Cleofas, located south of Mar{\'\i}a Cleofas Island, marks the limit between the RP and the JB along 100 km. It may be the result of the RP pushing against the JB establishing the beginning of the current subduction process, with associated seismic activity. If a subduction type earthquake occurs in this area, the associated magnitude will be about 7.5 and could have a tsunamigenic effect.}, doi = {10.1785/0220150144}, url = {http://www.scopus.com/inward/record.url?eid=2-s2.0-84954306785\&partnerID=40\&md5=ad4bbdb5d2b001b4510745d3e92ea302}, author = {N{\'u}{\~n}ez-Corn{\'u}, F J and C{\'o}rdoba, D and Da{\~n}obeitia, J J and Bandy, W L and Figueroa, M O and Bartolom{\'e}, R and N{\'u}{\~n}ez, D and Zamora-Camacho, A and Esp{\'\i}ndola, J M and Castell{\'o}n, A and Escudero, C R and Trejo-G{\'o}mez, E and De Jes{\'u}s Escalona-Alc{\'a}zar, F and Plascencia, C S and Alejandro Nava, F and Mortera, C} }
