Researchers Discover Fiji Island Formed by Human Activity

Researchers working off the coast of Kulasavani on the northern island of Vanua Levu in Fiji have made a remarkable discovery that could change our understanding of island formation in the Pacific Ocean. A 3,000 square meter object, previously thought to have been created by a powerful tsunami, has been revealed to be a result of human activity. This finding challenges traditional notions of natural disasters and their impact on landscape formation.

The geoarchaeological survey indicated that this small island, which rises 60 centimeters above the average high tide, is almost entirely composed of remains of edible mollusks mixed with sandy clay. This discovery suggests that the island may be the result of the accumulation of food waste left by the region's first settlers.

Analysis of materials brought to the surface by crabs from depths of up to 50 centimeters confirmed that the shell deposits are not superficial. Radiocarbon dating indicates that the bulk of the deposits formed around 1,200 years ago, approximately in the year 760 AD. This evidence points to a significant history of human activity associated with the island.

Initially, scientists speculated that the shells had been washed ashore by a giant wave, but the uniformity of the species of mollusks found suggests otherwise: these were food waste from the first settlers. Such formations in archaeology are referred to as "midden heaps" or shell middens. In the western Pacific, ancient peoples whose diets were based on seafood often discarded shells in shallow waters. Over time, these wastes accumulated, and along with the natural lowering of sea levels, formed solid land suitable for habitation.

Supporting this hypothesis are fragments of pottery found at the site, indicating the presence of human settlements in the region. If the theory of human-made origin is confirmed, this will mark the first documented case of an entire island formed from domestic waste in the southern Pacific, west of Papua New Guinea.

The research team is currently planning to conduct further studies to definitively rule out the tsunami factor and to explore oral traditions of local residents, which may hold memories of the formation of this unusual landmass. The results of their work have already been published in the scientific journal Geoarchaeology, underscoring the significance of this discovery for archaeology and geoarchaeology.
