Sismotectonics and geodynamics characterization of Murindo - Colombia seismic source

Northwestern South America is a convergence zone of three major tectonic plates, Nazca, Caribbean and South America and microplates or blocks such as Panama-Costa Rica, Choco and the Northern Andean or Macondo. The displacement of these plates and microplates produce seismotectonic stresses, which h...

The displacement of these plates and microplates produce seismotectonic stresses, which have generated strong earthquakes when release. The seismic events occurred in this zone are shallow focus and destructive, reaching up to Ms = 7.5. Using empirical mathematical relationships with magnitude Ms ≥ 3,9, focal mechanism solutions and GPS plate tectonic displacement vectors, the seismotectonic deformation was analyzed. This deformation is represented by the North component of the seismic moment tensor. Low deformation velocity was obtained, which is in contrast with those determined by GPS. Therefore, we proposed that the regional stresses do not behave homogeneously on the zone.  La esquina noroccidental de Suramérica es una zona de convergencia de tres placas tectónicas principales, Nazca, Caribe y Suramericana, Acosta, J.

El movimiento de estas placas y microplacas generan esfuerzos deformantes que al liberarse, causan sismos fuertes. Los sismos ocurridos en esta zona son superficiales y destructores, y de acuerdo con los cálculos podrían alcanzar magnitudes Ms hasta de 7,5. El análisis de la deformación producida por estos eventos fue determinada a partir de relaciones matemáticas empíricas utilizando datos de magnitud Ms ≥ 3,9, solución de mecanismos focales, y datos de mediciones realizadas con geodesia satelital GPS (Sistema de Posicionamiento Global). La deformación sismotectónica predominante se especifica por la componente del tensor de momento sísmico en sentido norte. Las velocidades de deformación obtenidas a partir de datos sismológicos son muy bajas, a diferencia de las obtenidas por GPS, lo cual muestra que los esfuerzos regionales no actúan de forma homogénea en la zona.  application/pdfspaUniversidad Industrial de Santanderhttps://revistas.uis.edu.co/index.php/revistaboletindegeologia/article/view/863/1192Boletín de Geología; Vol. 27 Núm. 1 (2005): Boletin de Geología; 115-132Boletín de Geología; Vol. 27 No. 1 (2005): Boletin de Geología; 115-132BOLETÍN DE GEOLOGÍA; v. 27 n. 1 (2005): Boletin de Geología; 115-1322145-85530120-0283Seismotectonicgeodynamicsfocal mechanisms solutionsstrain rateMurindó ZoneGPSsismotectónicageodinámicamecanismos focalesvelocidad de deformaciónZona de MurindóGPSSismotectonics and geodynamics characterization of Murindo - Colombia seismic sourceCaracterización sismotectónica y geodinámica de la fuente sismogénica de Murindó - Colombiainfo:eu-repo/semantics/articlehttp://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/resource_type/c_2df8fbb1Cardona, C.Salcedo, E. de J.Mora, H.20.500.14071/5011oai:noesis.uis.edu.co:20.500.14071/50112022-03-16 12:39:34.158metadata.onlyhttps://noesis.uis.edu.coDSpace at UISnoesis@uis.edu.co
