Volcanic group in the context of "Complex volcano"

The Territory of Heard Island and McDonald Islands (HIMI) is an Australian external territory comprising a volcanic group of mostly barren Antarctic islands, about two-thirds of the way from Madagascar to Antarctica. The group's overall land area is 372 km (144 sq mi) and it has 101.9 km (63 mi) of coastline. Discovered in the mid-19th century, the islands lie on the Kerguelen Plateau in the southern Indian Ocean and have been an Australian territory since 1947.

Heard Island and McDonald Islands contain Australia's only two active volcanoes. The summit of one, Mawson Peak, is higher than any mountain in all other Australian states, territories or claimed territories, except Dome Argus, Mount McClintock and Mount Menzies in the Australian Antarctic Territory. This Antarctic territory is a land claim unrecognised by most other countries, meaning that Mawson Peak is the highest mountain with undisputed Australian sovereignty.

The Banda Islands (Indonesian: Kepulauan Banda) are a volcanic group of ten small islands in the Banda Sea, about 140 km (87 mi) south of Seram Island and about 2,000 km (1,243 mi) east of Java, and constitute an administrative district (kecamatan) within the Central Maluku Regency in the Indonesian province of Maluku. The islands rise out of 4-to-6-kilometre (2.5 to 3.7 mi) deep ocean and have a total land area of approximately 172 square kilometres (66 sq mi); with associated maritime area this reaches 736.3 square kilometres (284.3 sq mi). They had a population of 18,544 at the 2010 Census and 20,924 at the 2020 Census; the official estimate as of mid-2023 was 21,902. Until the mid-19th century the Banda Islands were the world's only source of the spices nutmeg and mace, produced from the nutmeg tree. The islands are also popular destinations for scuba diving and snorkeling. The main town and administrative centre is Banda Neira, located on the island of the same name.

The Daisetsuzan Volcanic Group (大雪山系, Daisetsu-sankei; also called Taisetsu-zan) is a volcanic group of peaks arranged around the 2 kilometres (1.2 mi) wide Ohachi-Daira (御鉢平, Ohachi-daira) caldera in Hokkaidō, Japan. In the Ainu language it is known as Nutapukaushipe (which means "the mountain above the river"), Nutaku Kamushupe, or Optateske. These peaks are the highest in Hokkaidō. The group lends its name to the Daisetsuzan National Park in which the volcanic group is located.

Tomuraushi Volcanic Group (トムラウシ火山群, Tomuraushi-kazangun) is a volcanic group in Hokkaidō, Japan. Along with the Daisetsuzan Volcanic Group they make up the Ishikari Mountains in Daisetsuzan National Park. The group consists of andesite and dacite stratovolcanoes and lava domes.

The Hakkōda Mountains (八甲田山系, Hakkōda-sankei) are an active volcanic complex in south-central Aomori Prefecture, Japan, in Towada-Hachimantai National Park. Often called Mount Hakkōda (八甲田山, Hakkōda-san) or simply Hakkōda (八甲田), the mountains are collectively listed as one of the 100 Famous Japanese Mountains. Its highest peak, Mount Ōdake, lies 21.3 kilometers (13.2 mi) southeast of central Aomori and 28 kilometers (17 mi) west of central Towada and has an elevation of 1,585 meters (5,200 ft). The Hakkōda Mountains are a part of the Ōu Mountains which make up part of the Northeastern Japan Arc, a segment of the Pacific Ring of Fire. The volcanic complex consists of fourteen stratovolcanoes and lava domes arranged into two volcanic groups. The Northern Hakkōda Volcanic Group emerges from the rim of an 8-kilometer-wide (5.0 mi) caldera that dates back to the Pleistocene. The Southern Hakkōda Volcanic Group predates the caldera.

The Hakkōda Mountains attract many climbers, skiers, and sightseers. The mountains offer extensive backcountry skiing in the winter and early spring. There is a lift, the Hakkōda Ropeway in the northern Hakkōda Mountains used by visitors year-round and several hiking trails cross the mountains. While the trails do not pose any technical climbing challenges, Hakkōda presents dangers such as volcanic gases, harsh winter weather, and avalanches. The most notable incident in mountains' history was the Hakkōda Mountains disaster, the worst mountaineering accident in modern history.

The Duluth Complex, the related Beaver Bay Complex, and the associated North Shore Volcanic Group are rock formations which comprise much of the basement bedrock of the northeastern part of the U.S. state of Minnesota in central North America. The Duluth and Beaver Bay complexes are intrusive rocks formed about 1.1 billion years ago during the Midcontinent Rift; these adjoin and are interspersed with the extrusive rocks of the North Shore Volcanic Group produced during that same geologic event. These formations are part of the Superior Upland physiographic region of the United States, which is associated with the Laurentian Upland of the Canadian Shield, the core of the North American Craton.

Jolo (Tausug: Sūg) is a volcanic island in the southwest Philippines and the primary island of the province of Sulu, on which the capital of the same name is situated. It is located in the Sulu Archipelago, between Borneo and Mindanao, and has a population of approximately 500,000 people.

The island is the location of the Jolo Group of Volcanoes, an active volcanic group, and contains numerous volcanic cones and craters, including the active Bud Dajo cinder cone. It has been the headquarters of militants from the terrorist group Abu Sayyaf.

The Monti della Tolfa (or Tolfa Mountains) are a volcanic group in the Anti-Apennines of the northern part of the Lazio region of Central Italy. They are bounded by the Tyrrhenian Sea coast to the west, by the Monti Sabatini to the east, and by the Monti Cimini and the Mignone river to the north. Tolfa and Allumiere are the principal towns.

The highest peak is the Monte Maggiore (633 m above sea level). The Monti della Tolfa consists mostly of trachytes formed during the Eocene and the early Pleistocene.
