TheBagre Norte Fault (Spanish:Falla de Bagre Norte) is a sinistralobliquestrike-slip fault in thedepartments ofAntioquia andBolívar in northernColombia. The fault has a total length of 159.3 kilometres (99.0 mi) and runs along an average north to southstrike of 359 ± 14 along theCentral Ranges of the ColombianAndes and theSerranía de San Lucas.
The fault is named afterEl Bagre.[1]
The Bagre Norte Fault branches from thePalestina Fault, close to theAlicante River. The fault juxtaposesPrecambrianmetamorphic rocks on the east againstsedimentary rocks in the west. The fault shows as a prominent topographic lineament on satellite images and aerial photographs. Prominent scarp faces west, the fault appears to displace erosion surfaces of theCentral Ranges about 200 metres (660 ft). The strong geomorphologic expression suggestsQuaternary activity.[1]
