Cinder cone - Wikipedia
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 - U.S. National Park Service
Most cinder cones are a few hundred feet tall (100 to 150 m), and rarely are larger than 600 to 900 feet (200 to 300 m) in height. Each cinder cone usually is its own edifice built up around a central vent. While sometimes they are nearly perfect cones like Sunset Crater Volcano, cinder cones frequently have an asymmetric shape.

Cinder Cone - Volcano Definition, Types of Volcanoes and FAQs
Cinder cones are the type of volcano that is formed by pyroclastic fragments like volcanic ashes, solidified lava pieces, volcanic clinkers, pumice and hot gases. These volcanoes are formed around the volcanic vent and are known to be the simplest form of a volcano.
USGS: Volcano Hazards Program Glossary - Cinder cone
Cinder cone A conical hill, often steep, formed by accumulation of solidified fragments of lava that fall around the vent of a single basaltic or andesitic eruption. The rock fragments, often called cinders or scoria , are glassy and contain numerous gas bubbles "frozen" into place as magma exploded into the air and then cooled quickly.
