	Types of Volcanoes	The Ring of Fire

There are many types of volcanoes:

• Shield Volcano - A gently-sloping volcano that emits mostly basaltic lava (very fluid lava) that flows in long-lasting, relatively gentle eruptions - explosions are minimal. Shield volcanoes can be very big. An example is Mt. Kilauea (in Hawaii, USA).
• Composite or Strato Volcano - A steep-coned volcano that explosively emits gases, ash, pumice, and a small amount of stiff, silica lava (called rhyolite). This type of volcano can have eruptions accompanied by lahars -- deadly mudflows. Most volcanoes on Earth are of this type. Stratovolcanoes kill more people than any other type of volcanoes - this is because of their abundance on Earth and their powerful mudflows. Examples are Krakatoa in Indonesia, Mt. Pinatubo in the Philippines, and Mt. St. Helens in Washington state, USA.
• Lava Dome - A bulbous (rounded) volcano that forms when very viscous lava barely flows. An example is Mont Pelée in Martinique.
• Cinder Cone - A cone-shaped volcano whose steep sides are formed by loose, fragmented cinders that fall to the Earth close to the vent. The lava flows through a single vent that is usually only up to about 1,000 feet tall. There is usually a bowl-shaped crater at the top. As the gas-filled lava erupts into the air, the lava fragments into pieces and forms cinders.
• Rhyolite Caldera Complex - these are the most explosive volcanoes. They do not look like common volcanoes -- after an eruption, the result is a caldera (crater) caused when the area around the vent collapses. Examples are Yellowstone in Wyoming, USA and Lake Taupo in New Zealand (which erupted around A.D. 80).
