Amasing volcano lies off the southern coast of Halmahera Island, Indonesia, on the small island of Bacan (Palau Batjan). Bukit Amasing (Amasing Hill) is the largest and NW most of 3 small andesitic volcanoes, the other two being Cakasuanggi and Dua Saundara. No recent activity is know from Amasing, and the volcanic edifice is strongly eroded, suggesting it might be extinct.
