Erupting cinder cone. Computer artwork showing the conical shape of a typical volcanic cinder cone. Cinder cones form from volcanic vents which erupt depositing a conical mound of loose volcanic rock fragments around them. These pyroclastic fragments, known as scoria, resemble cinders. Cinder cones are commonly found on the flanks of other volcanoes such as stratovolcanoes, shield volcanoes and calderas, but can also be volcanoes in their own right. They can be anywhere from around 30 to 400 metres high.
