Vanuatu is an archipelago of over 80 Islands. It extends from Mathew and Hunter Islands in the south to the volcanic Tinakula in the Solomons Islands to the north. The Vanuatu Island system lies on the edge of the Pacific tectonic plate which is being forced up and over the Indo Australian plate. This enormous pressure causes constant earthquakes and volcanic eruptions. Almost all of Vanuatu's Islands were born from this volcanic activity making their major building blocks' Basalt. Their Volcanic origins are reflected in the rugged and sometimes impenetrable interiors. Basalt forms when magma from the ocean surfaces through the sea floor. The rock cools very quickly which leaves little time for crystals to form making it fine grained and much softer than it's slower cooling partner Granite. Chemical Weathering is the major form of rock erosion in this warm / wet climate. The rain water dissolves many of the minerals in the rock, such as Calcium , Sodium and Magnesium making the Basalt break down relatively fast.
