Hotspot volcanism: Hotspot volcanism occurs when magma rises from a relatively persistent mantle source beneath a moving tectonic plate. A mantle hotspot is associated with the volcanic chain containing Salas y Gómez.
Jacob Roggeveen: Jacob Roggeveen was a Dutch explorer who led a Pacific expedition that reached Easter Island in 1722. His expedition is commonly credited with the island's European discovery in 1722.
Salas y Gómez Marine Park: Salas y Gómez Marine Park is a Chilean protected marine area surrounding Salas y Gómez Island. The park extends protection from the island across its surrounding ocean habitat.
Seamount: A seamount is an underwater mountain, usually formed by volcanic activity, whose summit lies below sea level. Salas y Gómez is the exposed summit of a largely submerged volcanic structure.
Nazca Plate: The Nazca Plate is an oceanic tectonic plate moving eastward beneath the western edge of South America. Its motion over mantle sources helped form volcanoes in this part of the Pacific.

Motiro Hiva Marine Park: Motiro Hiva Marine Park is a Chilean marine protected area encompassing Salas y Gómez Island and surrounding waters. This protected area gives the island a central role in Chilean ocean conservation.
Volcanic island: A volcanic island is land above sea level formed by volcanic eruptions on the seafloor. Its emergence above the Pacific is part of a broader pattern of oceanic volcanism.
Salas y Gómez Ridge: The Salas y Gómez Ridge is a submarine volcanic ridge extending through the southeastern Pacific between Easter Island and the Nazca Ridge. The island is the ridge's only feature rising above sea level.
