dc.description.abstractThis research project tests a thoroughly validated, well-formulated time-domain moment tensor inversion code in order to obtain in quasi real-time faulting parameters of signi cant earthquakes in the Northeastern Caribbean. The inversion code has been developed by Dreger and Helbei, (1991), and the main attractive feature is to decrease the time necessary to compute a moment tensor for any major earthquake using regional data. Six earthquakes in the study region have been used as testbed to the inversion code con gured for this area. In order to compare the results, previously computed and published moment tensor inversions from the Global Centroid Moment Tensor for the same events were used. Our results indicate the inversion method is capable of reproducing the regional solutions, and thus can be used for quick estimation of fault mechanism. However, a priori knowledge of which stations or station combination to use is needed to compute a moment tensor in real time applications.en_US
dc.description.abstractEsta investigación utiliza un código de inversión de tensor de momento con el n de obtener los parámetros de fuente de un terremoto regional signi cativo en tiempo real en la región del Noroeste del Caribe. Este código ha sido desarrollado por Dreger y Helbei, (1991), con el principal objetivo de disminuir el tiempo que se necesita para obtener un estimado de un tensor de momento para cualquier terremoto de gran magnitud utilizando datos regionales. Seis eventos sísmicos en la región de estudio se utilizaron para probar el código en dicha área. Con el n de comparar los resultados, se utilizaron tensores de momento previamente calculados para estos seis eventos sísmicos. Nuestros resultados indican que el método de inversión es capaz de reproducir soluciones regionales con ables que podrían ser utilizados para la estimación rápida de los parámetros de fuente de un terremoto. Sin embargo, es necesario conocimiento a priori de qué estación o combinación de estaciones se deben usar para calcular un tensor de momento en tiempo real.en_US
