SANCHEZ-ARREDONDO, Luis Hernán  y  GIRALDO-BOLIVAR, Orlando. Potential for geologically active faults Department of Antioquia, Colombia. Dyna rev.fac.nac.minas [online]. 2014, vol.81, n.185, pp.24-27. ISSN 0012-7353.  https://doi.org/10.15446/dyna.v81n185.34841.

A geostatistics module (mg₉₅) was determined based on geostatistical studies of global estimations of seismicity data reported by the National Seismological Network of Colombia [Red Sismológica Nacional de Colombia (RSNC)]. It enabled the level of activity of the cortical fault in the Department of Antioquia (DA), Colombia to be categorized. The mg₉₅ relates the estimated values with polygonal kriging and the corresponding error for each one of the municipalities of Antioquia, with a Student parameter at 95% confidence, dependant on the number of microseisms registered locally. The following categorization scale is proposed to determine the levels of active faults in each municipality: proved active fault mg₉₅∈[0-0.2], probable active fault mg₉₅∈[0.2-0.3], and possible active fault mg₉₅ > 0.3.

Palabras clave : seismology; geostatistics module; active faults; Colombia.
