The Abriaquí Fault (Spanish: Falla de Abriaquí) is an oblique thrust fault in the department of Antioquia in northwestern Colombia. The fault has a total length of 33.8 kilometres (21.0 mi) and runs along an average northwest to southeast strike of 311 ± 2 in the Western Ranges of the Colombian Andes.

Etymology

The fault is named after Abriaquí.[1]

Description

The Abriaquí Fault parallels the Cañasgordas Fault to the south, cutting Cretaceous oceanic volcanic rocks as well as Tertiary and Cretaceous sedimentary rocks. The fault has a well defined fault trace with scarps, saddles, and deflected streams. The slip rate is estimated at 0.2 to 1 millimetre (0.0079 to 0.0394 in) per year deduced from displaced geomorphologic features.[1]

gollark: Yet this happens.

gollark: If I suggested to people that we give out CB golds at random, and there was no raffle, I suspect we would end up with it being shouted down for unfairness.
