Usme Fault

The fault has a total length of 64.9 kilometres (40.3 mi) and runs along an average north-northeast to south-southwest strike of 022.7 ± 6 in the Eastern Ranges of the Colombian Andes.

[1] The Usme Fault is located in the Eastern Ranges of the Colombian Andes, south of Bogotá and extends along the western margin of the Tunjuelo River valley.

The fault forms a steep, prominent circa 40 metres (130 ft) high east-facing scarp on Cretaceous rocks that show initial development of triangular facets.

To the south of Bogotá, it appears that Pleistocene moraines are offset as recorded by east-facing well-preserved scarps about 3 metres (9.8 ft) high.
