SHIELD VOLCANO Long, gently sloping structures that produce at central vents. Eruptions are usually not explosive. Lava from underlying chambers may pour from vents across the surface. Kilauea and Mauna Loa are examples of shield volcanoes.
	CONE VOLCANO Rarely grow to 1,000 feet tall. Built by pyroplasts. Generally occur at cracks or weak zones. The Paricutin Volcano is an example of a cone volcano.
	STRATO-VOLCANO Large cone shaped structures produced at central vents. Half of volcano is lava. More Strato-volcanoes than any other. Mt. St. Helen's  and Mt. Fuji are examples of strato-volcanoes.
	SOMMA VOLCANO A Somma volcano is a caldera partially filled by a new central cone. They are named for Mt. Somma in Italy.  Medvezhia, Ebeko, Urataman, and Kolokol Group are all examples of Somma Volcanoes. Main spot for Somma volcanoes are the Kurile Islands.
	CALDERA VOLCANO After an eruption, a volcano may collapse and form a giant crater called a Caldera Volcano. 1 - 100 km in diameter. Most explosive of Earth's volcanoes.
