context_page_description: The North Andes Plate or North Andes Block is a small tectonic plate located in the northern Andes. It is squeezed between the faster moving South American Plate and the Nazca Plate to the southwest. Due to the subduction of the Malpelo and Coiba Plates, this area is very prone to volcanic and seismic activity, with many historic earthquakes.
context_section_description: The Colombian part of the North Andes Plate is subdivided into several terranes:
caption: • Chibcha Terrane is enclosed by the Bucaramanga-Santa Marta Fault (BSF, orange), northernmost Oca Fault (Oca, white), Eastern Frontal Fault System (EFFS, yellow) and Romeral Fault System (RFS, violet)
  • Tahamí Terrane is enclosed by BSF, OCA and RFS
  • Anacona, Arqúia and Quebradagrande Terranes are emplaced by RFS
  • La Guajira Terrane is enclosed by BSF and northernmost by Oca
  • Caribe Terrane is enclosed by BSF, RFS and plate boundaries with Coiba (red) and Malpelo Plates (purple)
