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.
Cinder cones typically only erupt once like Parícutin. As a result, they are considered to be monogenetic volcanoes and most of them form monogenetic volcanic fields. Cinder cones are typically active for very brief periods of time before becoming inactive. Their eruptions range in duration from a few days to a few years. Of observed cinder ...
Scoria cones are particularly prone to cluster into volcanic fields, which are typically 30–80 kilometers (19–50 miles) in diameter and consist of several tens to several hundred individual cones. The unusually large Trans-Mexican Volcanic Belt has nearly 1000 cones covering an area of 60,000 square kilometers (23,000 sq mi). [5]
Many monogenetic volcanoes are cinder cones, often with lava flows, such as Parícutin in the Michoacán-Guanajuato volcanic field, which erupted from 1943 to 1952. Some monogenetic volcanoes are small lava shields, such as Rangitoto Island in the Auckland volcanic field.

Cinder Cone is a 700 ft (210 m)-high volcanic cone of loose scoria. [5] The youngest mafic volcano in the Lassen volcanic center, [ 6 ] it is surrounded by unvegetated block lava and has concentric craters at its summit, [ 5 ] which have diameters of 1,050 ft (320 m) and 590 ft (180 m). [ 3 ]

Multiple successive and extensive lava flows cover the original landscape to eventually form a plateau, which may contain lava fields, cinder cones, shield volcanoes and other volcanic landforms. In some cases, a lava plateau may be part of a single volcano.
