| dc.description.abstract | Se relocalizan alrededor de 7400 eventos sísmicos del occidente de Colombia registrados por la Red Sismológica Nacional (RSNC) del Servicio Geológico Colombiano (SGC) a partir de la técnica Source-Specific Station Terms, que busca disminuir los efectos causados por las anomalías de velocidad en tres dimensiones obviadas por los modelos de velocidad tradicionales, generalmente unidimensionales (en capas). También se realiza correlación cruzada de formas de onda para encontrar similitud en grupos de eventos que permitan asociarlos a una misma fuente (o cercana), y poderlos localizar de manera relativa a partir del tiempo de desfase entre ellos. Además se prueban tres técnicas para hallar la solución de la inversión matricial en la que se obtienen las localizaciones finales, donde se encuentra que la solución por valor absoluto (norma L1) es la que mejores resultados arroja. Con estas nuevas localizaciones se observan estructuras que no son apreciables con la localización inicial evento por evento del catálogo consultado. Se delimitan las fallas de Murindó y Murrí, y se encuentra que la falla de Mutatá tiene manifestación sismológica mayor al sur de donde está cartografiada. Tambi ́en se encuentra un lineamiento con orientación ENE de mayor profundidad (31 km) costa afuera de Nuquí Chocó, que no ha sido reportado. | spa |
| dc.description.abstract | About 7400 seismic events in western Colombia registered by the National Seismological Network (RSNC) of Colombian Geological Survey (SGC) are relocated using the Source- Specific Stations Terms method that aims at reducing the effects caused by three-dimensional velocity anomalies not taken into account by traditional one-dimensional velocity models. Waveform cross-correlation is also performed to find similarities in clusters of events that allow the association with a similar or nearby source, and the relative relocation based on the phase delay time between them. In addition, three techniques are tested to find the solution of the matrix inversion in which the final locations are obtained, where we find that the solution by least absolute deviations (L1 norm), is the one that yields the best results. With these new locations, crustal structures are observed that are not apparent with the initial location event by event of the original catalog. The Murindó and Murrí faults are delimited, and it is found that the Mutatá fault has a greater seismological expression to the south of where it is mapped. There is also a seismicity alignment oriented towards ENE at 31 km depth offshore of Nuquí Chocó, which has not been reported. | spa |
