The Boconó Fault is a complex of geological faults located in the Eastern Ranges of northeastern Colombia and the Mérida Andes of northwestern Venezuela. The fault has a NE-SW orientation; it is a strike-slip fault and has a dextral relative movement.[1] It extends over a length of 500 kilometres (310 mi). The fault, with a slip rate ranging from 4.3 to 6.1 millimetres (0.17 to 0.24 in) per year, has been active since the Early Holocene and earthquakes of 1610 and 1894 are associated with it.[2]
