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.
In volcanology, a Strombolian eruption is a type of volcanic eruption with relatively mild blasts, typically having a Volcanic Explosivity Index of 1 or 2. [1] Strombolian eruptions consist of ejection of incandescent cinders, lapilli, and volcanic bombs, to altitudes of tens to a few hundreds of metres. The eruptions are small to medium in ...
Lacking a central volcanic cone, the Svartsengi volcanic system consists of a set of fissures, cones and volcanic craters aligned over 30 km (19 mi) in length and 7 km (4.3 mi) in width, oriented north-east to south-west and surrounded by fields of lava: [3] Þorbjörn (243 m (797 ft)), Hagafell (158 m (518 ft)), Sundhnúkur 134 m (440 ft) (Sundhnúksgígar means the associated crater row ...
Royal Society Volcano, Antarctica; Cerro Volcánico, Argentina; Mount Mayabobo, Philippines; Bombalai Hill (Sabah, Malaysia); Geghama mountains, Armenia; Chaîne des Puys, France (a chain of volcanoes including cinder cones)
S P Crater is a cinder cone volcano in the San Francisco volcanic field, 25 miles (40 km) north of Flagstaff, Arizona, United States. [4] It is surrounded by several other cinder cones which are older and more eroded. It is a striking feature on the local landscape, with a well-defined lava flow that extends for 4.3 miles (7 km) to the north. [5]

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, satellitic cone or lateral cone) is the cone-shaped accumulation of volcanic material not part of the central vent of a volcano.
