The possible existence of a now-submerged volcano off the coast of Papua New Guinea is inferred from oral tradition. Oral accounts from many villages along Madang coast report that the villagers fled from Yomba Island 8-10 generations ago when the island was destroyed by an eruption accompanied by a tsunami. The location of the former island is uncertain, but most informants placed it in the vicinity of the present-day Hankow Reef (Mennis, 1981). Hankow Reef lies between Bagabag and Crown Islands, NW of Long Island.
