The Córdoba-Navarco Fault (
The fault segment pertaining to the megaregional
Etymology
The fault is named after Córdoba and the Navarco River in Quindío.[1]
Description
The fault section is formed by the Córdoba and Navarco Faults, which are eastern strands of Romeral Fault System, south of the city of Armenia. These faults lie within the epicenter area of the Armenia earthquake of January 25, 1999. The faults extend through sheared cataclastic and undeformed basaltic and sedimentary Cretaceous oceanic rocks, cropping out on the eastern slope of the Central Ranges of Colombia.[1] It separates the Córdoba Complex from the Quebradagrande Complex.[2]
Well preserved fault trace controls stream drainages. The Córdoba-Navarco Fault forms fault saddles and eroded fault scarps. Neotectonic features are not very outstanding. Slopes in this part of the Central Ranges are rather steep, so erosion rate is high.[1]
The fault terminates in the south against the Ibagué Fault.[3]
Activity
On January 25, 1999 a major earthquake hit the capitals of Quindío, Armenia, and
