La Dina Fault
La Dina Fault (Spanish : Falla La Dina ) is a regional dextral oblique thrust fault in the departments of Huila and Tolima in southwestern Colombia . The fault has a total length of 206.9 kilometres (128.6 mi) and runs along an average northeast to southwest strike of 032.9 ± 13 in the Upper Magdalena Valley and the Central Ranges of the Colombian Andes .
Description
La Dina Fault lies east of La Plata Fault in southwestern Colombia. The fault displaces Jurassic (Saldaña Formation ), Cretaceous (Chicoral and Olini Groups ), and Tertiary (Honda Group ) sedimentary rocks , which are common in the Upper Magdalena Valley . Local names assigned to the southern extension of this fault are from north to south: Betania, Pital-Agredo and Magdalena.[ 1] It is also called the El Agrado-Betania Fault in Huila, where it underlies the Betania Reservoir .[ 2] The fault is marked by well-developed trace, abrupt slope changes, saddles, and small scarps .[ 1]
