A submarine eruption that began on May 8, 2026, continues in the central Bismarck Sea, about 130 km (81 miles) southeast of Manus Island, Papua New Guinea. The eruption revealed a previously unmapped underwater volcano, now provisionally named Titan Ridge Volcano, in a remote and tectonically active area of the Pacific Ocean.
