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 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 ]
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 ...

Magma erupting under pressure can solidify into scoria, which may fall and pile up around a crater to form circular and elliptical scoria cones and cinder cones. These are popularly known as oreum in Jeju Island. There are about 360 such oreum. Oreum are classified as cinder cones, lava domes, fault blocks, or cryptodomes. [4]
Lava Butte is a cinder cone in central Oregon, United States, just west of U.S. Route 97 between the towns of Bend, and Sunriver in Deschutes County.It is part of a system of small cinder cones on the northwest flank of Newberry Volcano, a massive shield volcano which rises to the southeast.
Cerro Negro is a polygenetic cinder cone that is part of the Central America Volcanic Arc, which formed as a result of the Cocos Plate subducting under the Caribbean Plate, at a rate of 9 cm (3.5 in) per year. It is the largest and southernmost of four cinder cones that have formed along a NW-SE trend line in the Cordillera de los Maribios ...
Schonchin Butte is a cinder cone on the northern flank of Medicine Lake Volcano in the Cascade Range in northern California. Frothy lava, cooled in the air, created the large cinder cones throughout Lava Beds National Monument. It is named for Old Schonchin, a chief of the Modoc people during the late nineteenth century. Erupting more than ...
