A tuff cone, sometimes called an ash cone, is a small monogenetic volcanic cone produced by phreatic (hydrovolcanic) explosions directly associated with magma brought to the surface through a conduit from a deep-seated magma reservoir. They are characterized by high rims that have a maximum relief of 100–800 meters (330–2,620 ft) above the ...
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.

The Puʻu ʻŌʻō and Mauna Ulu eruptions of Kīlauea have also formed small littoral cones. [7] Examples of littoral cones include Sand Hills (1840 eruption) on Kīlauea in Hawaiʻi, [23] ʻAuʻau, Nā Puʻu a Pele, Puʻu Hou (1868 eruption) and Puʻu Kī (eruption 1300 years ago) at Mauna Loa in Hawaiʻi, [6] a cone close to Villamil at ...
Parasitic cone (in foreground) with larger main cone in background, at Piton de la Fournaise volcano on the island of Réunion. A parasitic cone (also adventive cone, satellite cone or lateral cone) is the cone-shaped accumulation of volcanic material not part of the central vent of a volcano. It forms from eruptions from fractures on the flank ...
A volcanic field is an area of Earth's crust that is prone to localized volcanic activity. The type and number of volcanoes required to be called a "field" is not well-defined. [1] Volcanic fields usually consist of clusters of up to 100 volcanoes such as cinder cones. Lava flows may also occur.

The most important types of volcanic mountain are composite cones or stratovolcanoes and shield volcanoes. [10] [11] A shield volcano has a gently sloping cone because of the low viscosity of the emitted material, primarily basalt. Mauna Loa is the classic example, with a slope of 4°-6°.
