 Complex Volcano - John Seach

Complex volcanoes are mixed landforms. In most cases, they occur because of changes either in eruptive
habit or in location of the principal vent area. A stratovolcano may form a large explosion crater that later
becomes filled by a lava dome, or several new cones and craters may develop on a caldera's rim. One
stratovolcano cone may overlap another and have multiple summits.

Examples of Complex Volcano
McDonald Island (Australian Territory, Indian Ocean), Long Island (PNG),
Guntur (Java, Indonesia), Dieng (Java, Indonesia), Dukono (Halmashera, Indonesia),
Unzen (Japan), Asama (Japan), Iwate (Japan)
