Volcanoes & Cultures: The contrast between unspoiled rain-forest, coconut palm beaches, primitive culture and moon-like landscapes surrounding lava-spitting volcanoes could not be bigger: join us on an expedition to the two most active volcanoes of Vanuatu: Ambrym and Yasur.

Kilauea volcano photos: The most active volcano in the world with a record long lasting eruption since 1983: images of lava flows, lava lakes, explosions, lava meeting the ocean, aerials and more.

Divergent plate boundaries in oceans: Two ocean plates move apart from each other. Hot upwelling mantle material forms magmas that continuously produce new oceanic crust. An ocean widens.
