Resumen
Este proyecto de tesis permitió establecer una correlación entre señales electromagnéticas (EM) y eventos sísmicos que ocurren en el sistema litosférico colombiano. La correlación de eventos se realizó con datos provenientes de la Red Sismológica de la Sabana de Bogotá (RSSB), una red sismológica temporal en Chichimene (Acacías, Meta) y la Red Sismológica Nacional de Colombia. El proyecto contempló las fases de diseño y pruebas de desempeño de instrumentos necesarios para correlacionar señales. Dentro de los principales hallazgos se encontró una ausencia casi completa de perturbaciones eléctricas visibles conocidas como Señales eléctricas sísmicas (SES) y muy pocas de tipo magnético. Sin embargo, otro tipo de perturbaciones magnéticas que fueron encontradas son prometedoras para análisis a largo plazo.
Abstract: With this research was possible to establish a correlation between electro-magnetic (EM) signals on the ground surface and seismic events on the Colombian lithospheric system. The events correlation was made with data from the Seismological Network of the Sabana de Bogotá (RSSB for its acronym in Spanish), a temporal seismological network on Chichimene (Acacías, Meta) and the National Seismological Network of Colombia (RSNC, for its acronym in Spanish). The project considered the design and preliminary tests for the necessary instruments to correlate the signals. Among the main results are the almost complete lack of electric disturbances known as SES and not too much of magnetic kind. However, another kind of magnetic disturbances where found which are promising for long term experiments.
