The Effects of Climate Change, Vulnerability and Natural Disasters on the National Geodetic Network
Martin Sokomanu
The Vanuatu National Geodetic Network provides the fundamental support for high precision monitoring of crustal movements and climate change impacts, land surveying, mapping, engineering and related applications and is the basis for the integration of all such activities. It is the basic reference framework for all surveying, mapping and land related information. The geodetic network controls the position, extent and orientation of surveys throughout the Archipelago. Historically Vanuatu sits within the Pacific rim of fire stretching from the Torres group to Mathew and Hunter Island. This Island Arc system is a resultant of the Pacific plate colliding with the indo Australian plate, forming a volcanic chain of islands. The New Hebrides trench is divided into two parts by the D'entaucastroux ridge which rises some 1500m and collides with the trench between Santo and Malekula.
