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.
Igneous or magmatic rocks
: The most primitive rock type forms when magma (molten rock) solidifies - either inside the earth (plutonic rocks) or during volcanic eruptions (volcanic rocks). A short overview.
: 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.
