Cinder Cones in Bartolome island
These are normally found further inland than tuff cones, and on the flanks of the main volcano. They are often termed ‘parasitic cones’ , and are frequently nearly perfect cone shapes. Cinder cones are the result of very explosive eruptions, where there is a lot of gas in the magma, which expands rapidly as the magma comes to the surface. The cinder or scoria is used on the inhabited islands to make roads, which are very dusty when dry.
