Umboi (also named Rooke or Siassi) is a volcanic island between the mainland of Papua New Guinea and the island of New Britain. It is separated from New Britain by Dampier Strait and has an elevation of 1,548 m. Umboi is a Holocene complex volcano with no historic eruptions. A complex volcano refers to the extensive assemblage of spatially, temporally, and genetically related major and minor volcanic centers with their associated lava and pyroclastic flows.
It is said (by some natives and by some American investigators) to be the home of the Ropen, a nocturnal creature, more pterosaur-like than bat-like, that eats fish, according to the book Searching For Ropens
