This is a list of ca. 137 volcanoes in Chile. According with archivonacionaldevolcanes.cl[1] there are ca. 500 volcanoes, with 123 active - volcanoes that have erupted at least once in the Holocene. The volcanodb.com lists 109[2] and the Global Volcanism Program lists 105 volcanoes in Chile.[3]
The Pacific islands of Chile are of volcanic origin. They have been formed from magma coming from three distinct hotspots, Easter, Juan Fernández and San Felix hotspots. The westernmost part of the ridges formed by these hotspots contain the most recently active volcanoes. Some volcanoes or groups of volcanoes are under surveillance of OVDAS because of their critical activity or nearness to big cities.
Scope
There is no single standard definition for a volcano. It can be defined from individual vents, volcanic edificies or volcanic fields. Interior of ancient volcanoes may have been eroded, creating a new subsurface magma chamber as a separate volcano. Many contemporary active volcanoes rise as young parasitic cones from flank vents or at a central crater. Some volcanic cones are grouped into one volcano name, for instance, the Tengger caldera complex, although individual vents are named by local people. The status of a volcano, either active or dormant, cannot be defined precisely. An indication of a volcano is determined by either its historical records, radiocarbon dating, or geothermal activities.
The primary source of the list below is taken from the "Volcanoes of the World" book, compiled by two volcanologists Tom Simkin and Lee Siebert,[a] in which active volcanoes in the past 10,000 years (Holocene) are listed.[4]

Pacific hot spot volcanoes
The Pacific islands of Chile are of volcanic origin. They have been formed from magma coming from three distinct hotspots, Easter, Juan Fernández and San Felix hotspots. The westernmost part of the ridges formed by these hotpots contain the most recently active volcanoes.
