What is "ivuhos"

Ivuhos (also known as Ibugos, Ibujos, Vuhus and Ibahos Island) is one of the islands of Batanes, the northernmost province of the Philippines. The uninhabited island is located west of Sabtang Island and is separated by a deep channel nearly wide.

Ivuhos Island is small and rather low, except a hill on the south end. A coral beach before the hill on the eastern side is the only safe landing place on the island. The shores on both sides of the channel are bordered by reef. The flood tide sets southward with a velocity from 3 to 4 knots, and the ebb northward.
