Para ello, se estudia la polarización de las ondas correspondientes a las fases S de eventos locales (asociados con los procesos de subducción Nazca-Suramérica y Caribe-Suramérica), al igual que la polarización de las ondas correspondientes a las fases SKS de eventos telesísmicos. Los eventos locales tienen una profundidad mayor a los 70 km, al igual que magnitudes mayores o iguales a 4.5, mientras que los eventos telesísmicos tienen distancias hipocentrales entre los 90°-130°, y magnitudes mayores o iguales a 6.5. La obtención de los parámetros de anisotropía sísmica (φ, δt) se realiza para cada una de las estaciones sísmicas pertenecientes a la Red Sismológica Nacional de Colombia, comprendiendo un periodo de registro de seis años consecutivos (2016-2021). Esta se lleva a cabo mediante los paquetes de libre acceso de Python llamados ObsPy y SplitWavePy. Como resultado, se establece un control mixto de la anisotropía en la corteza donde predomina la polarización de las ondas S al interior de las fallas sobre la polarización por acción de esfuerzos; se observan patrones erráticos de φ por la presencia de fluidos en la corteza; y se obtienen las orientaciones del flujo astenosférico bajo las losas que subducen con una convergencia generalizada orientada SW-NE bajo la esquina noroccidental de Suramérica. (Texto tomado de la fuente)This thesis consists of the estimation of seismic anisotropy parameters (φ, δt) for the different seismic stations in Colombia, relating the obtained results with the different regional tectonic features of the northwestern corner of South America. To achieve it, the polarization of S phases of local events (associated with Nazca-South America and Caribbean-South America subduction processes) and SKS phases of teleseismic events is studied. The local events have a depth below 70 km, as well as magnitudes above or equal to 4.5, while the teleseismic events have hypocentral distances between 90°-130°, and magnitudes above or equal to 6.5. The obtention of seismic anisotropy parameters (φ, δt) is done for each one of the seismic stations which belong to the Colombian National Seismological Network, comprising a record time of six consecutive years (2016-2021). This is done by free-access Python software known as ObsPy and SplitWavePy. As a result, a mixed control of the anisotropy in the crust is established, where it prevails a S wave polarization inside the faults rather than a polarization due to stresses; erratic patterns of φ due to the presence of fluids in the crust are observed; and orientations of astenospheric flow under the subducting slabs are obtained with a generalized convergence oriented SW-NE under the NW corner of South America.MaestríaSismología y Tectónica124 páginasapplication/pdfspaUniversidad Nacional de ColombiaBogotá - Ciencias - Maestría en Ciencias - GeologíaFacultad de CienciasBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá550 - Ciencias de la tierraMovimientos tectónicosSismologíaEarth movementsSeismologyTectónicaSismologíaAnisotropía SísmicaEsquina Noroccidental de SuraméricaShear Wave SplittingEstimación de la anisotropía sísmica en Colombia y su relación con rasgos tectónicos regionalesEstimation of seismic anisotropy in Colombia and its relationship with regional tectonic featuresTrabajo de grado - Maestríainfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/acceptedVersionDataPaperImageModelTextWorkflowhttp://purl.org/redcol/resource_type/TMColombiaAcevedo, J., Fernández-Viejo, G., Llana-Fúnez, S., López-Fernández, C., Olona, J.
