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.

Chikurachki (Russian: Чикурачки; Japanese: 千倉岳, Chikura-dake) is the highest volcano on Paramushir Island in the northern Kuril Islands.It is actually a relatively small volcanic cone constructed on a high Pleistocene volcanic edifice.
The island of Curaçao began to form within the past 145 million years, beginning in the Cretaceous, as part of the Lesser Antilles island arc.Because the island was submerged for large parts of its history, reef environments formed atop thick layers of mafic volcanic rock, producing carbonate sedimentary rocks.
Tao-Rusyr Caldera (Russian: Тао-Русыр) is a stratovolcano located at the southern end of Onekotan Island, Kuril Islands, Russia.It has 7.5 km wide caldera formed during a catastrophic eruption less than 10,000 years ago (reported ages range from 5,550 to 9,400 Before Present).
