A cinder cone (or scoria cone [1]) is a steep conical hill of loose pyroclastic fragments, such as volcanic clinkers, volcanic ash, or scoria that has been built around a volcanic vent. [2] [3] The pyroclastic fragments are formed by explosive eruptions or lava fountains from a single, typically cylindrical, vent.
Clinker Gulch) is a gulch extending from Lucifer Hill to the north shore of Candlemas Island, South Sandwich Islands The name applied by the UK Antarctic Place-Names Committee in 1971 reflects the actively volcanic, sulphurous nature of the area, and the loose piles of lava debris, resembling furnace clinkers, which wall the gulch.
The volcanic activity in the South Island of New Zealand terminated 5 million years ago as the more northern parts of the North Island became extremely volcanically active. . The South Islands surface geology reflects the uplift of the Pacific plate as it collides with the Indo-Australian plate along the Alpine Fault over the last 12 million years and the termination of subduction, about 100 ...
Makian (also Machian), known to local people as Mount Kie Besi, [1] is a volcanic island, one of the Maluku Islands within the province of North Maluku in Indonesia.It lies near the southern end of a chain of volcanic islands off the western coast of the province's major island, Halmahera, and lies between the islands of Moti and Tidore to the north and Kayoa and the Bacan Group to the south.

Volcanic cones are among the simplest volcanic landforms. They are built by ejecta from a volcanic vent , piling up around the vent in the shape of a cone with a central crater. Volcanic cones are of different types, depending upon the nature and size of the fragments ejected during the eruption.
Nishinoshima (Japanese: 西之島, "western island") is a volcanic island located around 940 km (584 mi) south-southeast of Tokyo that is part of the Volcano Islands arc. . Nishinoshima is located about 130 km to the west of the nearest inhabited Ogasawara islands, Chichijima Island, hence the name; the other Ogasawara island groups are aligned more to the north–
The island has an area of 2.3 square kilometres (0.89 sq mi) and its highest point is 435 metres (1,427 ft). The peak is a well-defined volcanic crater . In 1981 the island was the centre of earthquakes.
Chikurachki (Russian: Чикурачки; Japanese: 千倉岳, Chikura-dake) is the highest volcano on Paramushir Island in the northern Kuril Islands.It is actually a relatively small volcanic cone constructed on a high Pleistocene volcanic edifice.
