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.

A littoral cone lies on the right, on top of the cliffs. Littoral cones are a form of volcanic cone. They form from the interaction between lava flows and water. Steam explosions fragment the lava and the fragments can pile up and form a cone. Such cones usually form on ʻaʻā lava flows, and

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 ...

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.
