Abstract

CHICANGANA, Germán et al. The Seismic Hazard of the Savanna of Bogota with Respect to an Earthquake of Magnitude M > 7.0 Originating in the Llanos Foothills. Cuad. Geogr. Rev. Colomb. Geogr. [online]. 2015, vol.24, n.2, pp.73-91. ISSN 0121-215X.  https://doi.org/10.15446/rcdg.v24n2.43865.

This work reveals how a major earthquake originating in the Eastern Frontal Fault System (Sistema de Fallas de la Falla Frontal de la Cordillera Oriental - SFFFCO) can cause great damage and loss of life in both the metropolitan area of Bogota D.C. and the remainder of the Savanna of Bogota. The degree of seismic hazard for the city in the case of a near-field earthquake with a magnitude > 7.0 originating in the Llanos Foothills, less than 250 km away, is extremely high given that soils of lagoon origin are located to the west and northwest of the city, regions where the metropolitan area has extended during the past two decades.

Keywords : seismic hazard; faults of the Llanos Foothills; Savanna of Bogota; lagoon soils.
