16 strombolian cones such as Mount Etna in Sicily, on which there are 250 small monogenetic cones;
in the centre of calderas where there is a ‘rift zone’ formed of a series of linear faults, such as on Teide volcano, Tenerife, Spain.

The IUCN thematic study (World Heritage Volcanoes: A Thematic Study, 2009, n°8), which aims to guide future inscriptions on the volcanic sites list, distinguishes several volcanic classifications, mainly based on the nature and eruptive style of the volcanic provinces (polygenetic/stratovolcano or monogenetic), the lava chemistry and resulting flow reliefs, as well as the geotectonic environment and geostructural context. On the basis of these characteristics a large number of volcanoes can be eliminated from this comparative study, notably those which:
Associated with the East African Rift, an example of a major fault, but located directly on the fault, following the classic tectonic model
Intracontinental volcanic ensemble, but composed of 9 active stratovolcanoes
Democratic Republic of Congo
(In danger since 1994)
Type volcanic site: birthplace of classic research methods and volcanological terminology
Emblematic of hotspot volcanism
2 most active stratovolcanoes in the world: changing landscape
United States
Large active volcanic chain over a length of 2,500 km, essentially andesitic stratovolcanoes
New Zealand
Typical island arc chain of stratovolcanoes: subduction volcano systematics
Japan
Shiretoko
Huge volcanic peninsular resulting from subduction, wide variety of volcanoes and forms. Active stratovolcanoes and seismicity
Russia
Volcanoes of Kamchatka
Cenozoic volcanism notable for its intrusive complexes and erosion features
Niger
(In danger since 1992)
Reference site for volcanology, gave its name to 2 eruptive styles, highly important site for volcano surveying
Stratovolcanoes
Volcanic archipelago: subduction volcanism
Italy
Aeolian Islands
Volcanic landscape island arc, subduction zone
Saint Lucia
Pitons Management Area
There are rare examples of individual monogenetic edifices, but the majority of this type of structure occurs in ‘fields’. Monogenetic fields are often found as secondary structures on the flanks of stratovolcanoes:
Air and Ténéré Natural Reserves
scientific research.
Tongariro National Park
structural setting; Accessible volcanic ensemble located within a relatively limited geographical area, volcanological history of the 19th century
Vocanic landscape island arc, stratovolcano, subduction zone
Spain
Teide National Park
are polygenetic or centred around a large, main edifice rather than in a monogenetic field like the Chaîne des Puys.
Hawaii Volcanoes National Park
volcanology; are at the edge of tectonic plates rather than being in an intra-continental setting;
Virunga National Park
The unique Chaîne des Puys site, set in a geodynamic context which is itself unique, is outstanding in terms of:
Comparison with the Quaternary sites already inscribed on the World Heritage List
Network of lava tunnels and shield stratovolcano and parasitic scoria cones built above a hotspot
Republic of Korea
Jeju Volcanic Island and Lava Tunnels
