Geology of Waya, Fiji

The peak of Vatu na Reba, “Rock of the Hawk”, Waya Island, Fiji, 1997. The basalt that makes up this peak formed underwater 6-8 million years ago, and it was subsequently pushed up and tilted to an incline of 25 degrees as the Fiji archipelago spun like a top across the Pacific basin. You can see the dramatic edges of this uplifted island, which emerged above the waves approximately 5 million years ago, along the western side of Waya.
