Image Collection | Types and Features | Scoria Cones
There are 5,976 volcano images available on the GVP website, including 4,240 in these new galleries with updated captions and keywords, and at a larger size.
Scoria cones (also called cinder cones) are the smaller of volcanic features and the most abundant, with tens to hundreds occurring in volcanic fields, on shield volcanoes and stratovolcanoes, and in calderas. They range from tens to hundreds of meters in height and are often formed during a single eruption period over days to years. They are largely composed of tephra and vesicular, glassy scoria clasts. They often produce lava flows that can erupt through a breach in the side of the cone or a vent on the flank. Hazards include ballistic ejecta, lava flows, pyroclastic flows (also called pyroclastic density currents), volcanic ash, volcanic lightning, and volcanic gas.
