Volcanic cones are among the simplest volcanic landforms. They are built by ejecta from a volcanic vent, piling up around the vent in the shape of a cone with a central crater. Volcanic cones are of different types, depending upon the nature and size of the fragments ejected during the eruption. Types of volcanic cones include stratocones ...
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.
Sunset Crater Volcano National Monument is a U.S. national monument created to protect Sunset Crater, a cinder cone within the San Francisco Volcanic Field. [14] The monument is managed by the National Park Service in conjunction with nearby Wupatki National Monument.
The cone shaped deposits are fairly uniform and consist primarily of tuff in lapilli-size particles. Some deposit layers preserve indentations, designated as "bomb sags", made as larger pyroclastic particles landed on soft layers of tuff. The Menan Buttes stand at an elevation of 5,619 feet (1,713 m.) and are very similar in size and shape.
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.

Pisgah Crater, or Pisgah Volcano, is a young volcanic cinder cone rising above a lava plain in the Mojave Desert, between Barstow and Needles, California in San Bernardino County, California. The volcanic peak is around 2.5 miles (4.0 km) south of historic U.S. Route 66 - National Old Trails Highway and of Interstate 40 , and west of the town ...
Then in April 2018, its 35-year-long eruption ended. The volcanic cone Puʻu ʻŌʻō stopped erupting as its crater floor collapsed, according to National Geographic. New eruptions are likely to ...
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.
