Volcanic cone

Volcanic cones are among the simplest volcano formations. They are built by fragments erupted from a 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 typically differentiated are spatter cone, cinder cone, ash cone, and tuff cone.

An example of a tuff cone is Diamond Head at Waikīkī in Hawai'i.

Schonchin Butte in Lava Beds National Monument is an old cinder cone
