Nyamuragira volcano photos
: Africa's version of Mauna Loa, Nyamuragira (or Nyamulagira) is a massive basaltic shield volcano neighboring Nyiragongo. It is one of the most active volcanoes in the world and has voluminous eruptions every few years.
Ijen volcano photos
: Ijen volcano in East Java is famous for its turquoise acid crater lake and the large sulfur deposits that are being mined by local workers. At night, the scene is illuminated by ghostly blue flames, as sulfur ignites.
: A third tectonic setting where volcanism occurs is believed to be the result of mantle plumes and not directly related to plate boundaries. So called hot spot volcanoes fall into this category.
