Tegua is an island in Vanuatu's Torres Islands chain. The only village is Lateu, with a population of 64. About 100 residents of Tegua were evacuated by the government because rising sea levels were flooding their island.
One geological study found that of four islands in the group, Tegua had the slowest inferred uplift rate at 0.7 mm/yr for southeastern Tegua. A "narrow E-W trending block has been down-dropped relative to the rest of the isle.
