8. STRATO VOLCANO Stratovolcanoes, also known as composite cones Stratovolcanoes, also known as composite cones When volcanoes are drawn, these are the most popular. When volcanoes are drawn, these are the most popular. The Strato is the most deadly of the volcano types. The Strato is the most deadly of the volcano types. Their lower slopes are gentle, but they rise steeply near the summit to produce an overall morphology that is concave in an upward direction.
