Malpelo Ridge

Last updated May 24, 2025

The Malpelo Ridge (Spanish : Dorsal de Malpelo) is an elevated part of Nazca plate off the Pacific coast of Colombia. It is a faulted chain of volcanic rock of tholeiitic composition.^[1] The Malpelo Ridge may have originated simultaneously as Carnegie Ridge, and thus represent an old continuation of Cocos Ridge.^[2] It is thought to have acquired it present position due to tectonic movements along the Panama fracture zone.^[2]
