The Santa Cruz Islands are a group of islands in the Pacific Ocean, part of Temotu Province of the Solomon Islands. They lie approximately 400 km (250 miles ) to the southeast of the Solomon Islands Chain and north of the archipelago of Vanuatu. The Santa Cruz Islands are less than five million years old, and were pushed upward by the tectonic subduction of the northward-moving Indo-Australian Plate under the Pacific Plate. The islands are mostly composed of limestone and volcanic ash over limestone.
