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 ...
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).

On that first day, the volcano had begun strombolian pyroclastic activity; and within 24 hours there was a scoria cone fifty meters high, created by the ejection of lapilli fragments up to the size of a walnut and larger, semi-molten volcanic bombs. By the end of the week, reports held that the cone was between 100 and 150 meters high.
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.
View from the top of Diamond Head, 2015. Diamond Head is a volcanic tuff cone on the Hawaiian island of Oʻahu.It is known to Hawaiians as Lēʻahi (pronounced [leːˈʔɐhi]), which is most likely derived from lae (browridge, promontory) plus ʻahi (tuna) because the shape of the ridgeline resembles the shape of a tuna's dorsal fin.

Eve Cone is part of the Mount Edziza volcanic complex, which consists of diverse landforms such as shield volcanoes, stratovolcanoes, lava domes and cinder cones. The cone contains a circular, 45 m (148 ft) deep summit crater and was the source of an extensive lava flow that travelled down the northern side of the Big Raven Plateau towards ...
Puʻu ʻŌʻō is a cinder/spatter cone in the eastern rift zone of the Kīlauea volcano of the Hawaiian Islands. Puʻu ʻŌʻō has been erupting continuously since January 3, 1983, making it the longest-lived rift-zone eruption of the last two centuries.
