La información para la parametrización de la corteza superficial y el magma, se obtuvo de estudios específicos preexistentes, y la solución de los sistemas de ecuaciones se realiza mediante el método de elementos finitos. Los resultados muestran un comportamiento anómalo en la dimensión fractal durante el emplazamiento de los domos de lava de 2006 y 2008. La caracterización sísmica evidencia la existencia de 9 familias de sismos LP que se distribuyeron en dos grupos G1 y G2, asociados respectivamente con el emplazamiento de los domos de lava en superficie y la sismicidad precedente a estos domos. Se parametrizaron modelos para los grupos, G1 y G2, los cuales tienen por diferencias principales: la longitud de la columna de magma y el tipo de acción de la fuente sísmica. Se propone la resonancia de una columna de magma de aproximadamente 2800 m de largo, cuyo tope casi alcanza la superficie, como posible causante de la sismicidad del grupo G1 y una columna cercana a los 2000 m como responsable de los sismos del grupo G2. Adicionalmente, los resultados de este estudio ponen en duda la efectividad de la localización de sismicidad de fluidos basda en el método de atenuación de amplitudes. (Texto tomado de la fuente).This study analyzes the Long Period-type seismicity (LP) registered in Galeras volcano in the 2004 – 2010 period, from aspects related to: 1) its temporal distribution by applying the technique of the variation in the fractal dimension, 2) the segmentation of the seismicity into families and groups of families, using cross-correlation method and the characterization of families and groups using spectral information, 3) the results generated in 1 and 2, serve as contextual support for the generation of resonance models of a magma column, within from which a disturbance is applied. This disturbance is propagated in the form of seismic waves through the interface between the column and the superficial crust until to reach a receptor. The reference information used for the parameterization of the superficial crust and magma properties was obtained from specific pre-existing studies, and the solution for the system of the equations is carried out using the finite element method (FEM). The results show anomalous behavior in the fractal dimension during the emplacement of the lava domes of 2006 and 2008. Seismic characterization reveals the existence of 9 families of LP earthquakes that were distributed into two groups, G1 and G2, associated with the seismicity preceding the lava domes (G2) and that associated with their emplacement on the surface (G1). Models for groups G1 and G2 were parameterized, which have as main differences: the length of the magma column and the form of action of the seismic source. The resonance of a magma column of approximately 2000 m long is proposed as a possible cause of the seismicity of G2 group, while a 2800 m long column, whose top almost reaches the surface, as responsible for the earthquakes of the G1 group. Additionally, the results of this study cast doubt on the effectiveness of locating fluids seismicity based on seismic waves amplitude attenuation method.Incluye anexosDoctoradoDoctor en GeocienciasSismología volcánicaxxi, 170 páginasapplication/pdfspaUniversidad Nacional de ColombiaBogotá - Ciencias - Doctorado en GeocienciasDepartamento de GeocienciasFacultad de CienciasBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá550 - Ciencias de la tierra::551 - Geología, hidrología, meteorologíaVolcanoesSeismologySeismic zonesVolcanesSismologíaZonas de actividad sísmicaVolcán GalerasSismos largo periodoResonancia de conductosGaleras volcanoLong period seismicityConduit resonanceModelos de fuente de sismicidad LP para la actividad del volcán Galeras 2004-2010 (Colombia)LP seismicity source models for the activity of the Galeras volcano 2004-2010 (Colombia)Trabajo de grado - Doctoradoinfo:eu-repo/semantics/doctoralThesisinfo:eu-repo/semantics/acceptedVersionhttp://purl.org/coar/resource_type/c_db06Texthttp://purl.org/redcol/resource_type/TDAki, K., Fehler, M., & Das, S.
