thumbA tuff cone, sometimes called an ash cone, is a small monogenetic volcanic cone produced by phreatic (hydrovolcanic) explosions directly associated with magma brought to the surface through a conduit from a deep-seated magma reservoir. They are characterized by high rims that have a maximum relief of 100-800 m above the crater floor and steep slopes that are greater than 25 degrees. They typically have a rim to rim diameter of 300-5000
