Subduction Zone volcanoes
◦ Most Volcanoes are subduction zone volcanoes
◦ Can develop at continental-oceanic converging
boundaries and oceanic-oceanic converging

boundaries
◦ Are less common than subduction zone volcanoes
◦ Tend to have more gentle eruptions that are mostly
lava
◦ Hawaiian islands are an example of hot spot
volcanoes
