Simberi Island is a volcanic island in the Tabar Group, in Papua New Guinea's New Ireland Province.〔(【引用サイトリンク】title=Simberi )〕 ==Geography and geology== Simberi is the northernmost and smallest of the three islands in the Tabar Group. The island is about 9 km long and 7 km wide and has an area of about 40 square kilometers. Its highest point in the highlands on the eastern side of the island is a 340 m eroded volcanic cone. The interior of the island is largely covered by rainforest. Most of the island's coast is steep and surrounded by a fringing reef together with a series of small islets. There is a barrier reef about 10 km offshore from the west coast. A 2 km strait separates Simberi from Tatau Island to the south west. Simberi island is a potassium rich (high-K) calc-alkaline island arc volcano, the oldest in the Pliocene to Holocene Tabar-Lihir-Tanga-Feni (TLTF) volcanic arc that formed above a subduction zone.
