PulauTiga is an uninhabited island in the Pacific Ocean, off the coast of North Borneo.
PulauTiga (the name means "Island of Three") was formed on September 21, 1897 when a large earthquake on the Philippine island of Mindanao triggered a volcanic eruption just north of Borneo.
PulauTiga is 6 miles (10 km) offshore of the island of Borneo, to the northeast of the country of Brunei.
