and the Pacific plate. The Fiji Platform lies in a zone bordered by active extension fault lines, around which most of the shallow earthquakes in the area have been centred. These fault lines are: the Fiji Fracture Zone (FFZ) to the north; the 176° Extension Zone (176°E EZ) to the west; and the Hunter fracture zone (HFZ) and Lau Ridge to the east. The oldest rocks on the island are those formed during the

Transportation

Ferry service, provided by the Patterson Brothers Shipping Company, connects Viti Levu to the rest of the islands. Nadi International Airport, on the island's northwest side, is the principal airport in Fiji. Nausori International Airport, on the southeast side, serves the city of Suva. It has service from 3 domestic commercial passenger airlines.
