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 Cone is in Lassen Volcanic National Park. 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).

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 ...
Roden Crater is a cinder cone type of volcanic cone from an extinct volcano, with a remaining interior volcanic crater. It is located approximately 50 miles northeast of the city of Flagstaff in northern Arizona, United States. [4]
Auquihuato [1] [2] (possibly from Quechua, awki: prince, watu: prediction, fortuneteller) [3] [4] is a cinder cone in the Andes of Peru, 4,980 metres (16,339 ft) high. [1] It is situated in the Ayacucho Region, Paucar del Sara Sara Province, on the border of the districts Colta and Oyolo. [5] Auquihuato lies northeast of Sara Sara volcano. [2]
El Jorullo is a cinder cone volcano in Michoacán, central Mexico, on the southwest slope of the central plateau, 33 miles (53 kilometers) southeast of Uruapan in an area known as the Michoacán-Guanajuato volcanic field. It is about 6 miles (9.7 km) east-northeast of La Huacana. Its current elevation is 4,360 ft (1,329 m).
It last erupted approximately 8,500–10,000 years ago and filled the valley with volcanic debris, raising the valley level to 400 feet above Clear Lake. [1] The Clear Lake Volcanic Field is the site of Late Pliocene to early Holocene activity and consists of lava domes, cinder cones, and maars [2] with eruptive products varying from basalt to ...
