Tinakula is the most active volcano in the Solomon Islands. It is located at the northern end of the New Hebrides Island arc, a chain of volcanic islands stretching between the Solomons and Vanuatu. Tinakula is one of the least known active volcanoes in the world. It's remote location in the eastern Solomons and the adventurous ocean crossing makes it infrequently visited.
