Major active faults have developed in the North Andean orogenic system that reveal moderate to high seismic hazard in the northwestern border of Colombia. This study presents a morphotectonic analysis of recent deformations along the Abriaquí fault and introduces new historical seismicity data that allows for preliminarily assigning the 1903 earthquake in Frontino to this structure, and modifying the age of its last displacement to historical time periods. © 2015.
