The fault has a total length of {{convert|36.1|km|mi}} and runs along an average northeast to southwest strike of 044.1 ± 4 in the Western Ranges of the Colombian Andes. EtymologyThe fault is named after the Guáitara River in Nariño.[1] DescriptionThe Guáitara Fault is in the Nariño Department of southwestern Colombia, crossing the Western Ranges of the Colombian Andes and to the south of the city of Pasto. The fault offsets Neogene volcanic rocks. The fault is believed to extend south into the Republic of Ecuador and may be part of the megaregional Romeral Fault System. The fault forms well developed deep V-shaped valleys, linear topographic features, fault-controlled drainage, deflected streams, and elongated hills.[1] See also{{portal|Colombia|Earthquakes|Geology|Prehistory of South America}}
