The Mulato-Getudo or Mulato-Jetudo Fault (

strike of 016.7 ± 9 in the Middle Magdalena Valley and along the western foothills of the Central Ranges of the Colombian Andes

.

Etymology

The fault is named after the Mulatos and Jetudo Rivers, left tributaries of the Magdalena River.^[1]

Description

The Mulato-Getudo Fault, in some parts called Jetudo Fault,^[2] extends along the eastern foothills of the Central Ranges of the Colombian Andes, where it marks the abrupt break in slope of the east-tilted Tertiary erosion surface of the Cordillera and the flat alluvial plains of the Magdalena River in the Middle Magdalena Valley. The fault forms a regional-scale degraded fault escarpment with an outstanding break in slope. It offsets Pliocene to Quaternary deposits and an extensive tilted erosional surface of probable Miocene to Pliocene age (pre-Mesa Formation, older than 1.5 Ma). The northern half of the fault is characterised by aligned drainages and broad valleys.^[1] The fault possibly underlies the Honda Group south of the La Miel River.^[3]
