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.
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.
Considered one of South Korea's most beautiful tourist sites, [1] [2] it is famed for being the easternmost mountain on Jeju, and thus the best spot on the island to see the first sunrise of the year.

The above sea-level portion measures approximately 84 metres east-west and 56 metres north-south, with a summit height of 99 metres (325 ft).

1257 Samalas eruption, Rinjani volcanic complex, Lombok Island, Indonesia; 40 km 3 (dense-rock equivalent) of tephra, Arctic and Antarctic Ice cores provide compelling evidence to link the ice core sulfate spike of 1258/1259 A.D. to this volcano.
More than two months after eruptions first began, the Cumbre Vieja volcano on La Palma, one of Spain's Canary Islands, continues to create new issues for residents. Since mid-September, residents ...
