The Sangihe Islands (also spelled "Sangir", "Sanghir" or "Sangi") – Indonesian: Kepulauan Sangihe – are a group of islands that constitute two regencies within the province of North Sulawesi, in northern Indonesia, the Sangihe Islands Regency (Kabupaten Kepulauan Sangihe) and the Sitaro Islands Regency (Kabupaten Siau Tagulandang Biaro).
The largest island is Sangir Besar and contains an active volcano, Mount Awu (1,320 meters (4,330 ft)).
The area came under Dutch control in 1677 and became part of Indonesia when it declared independence from the Netherlands in 1945.

15 years ago the practice of illegal fish bombing damaged the coral and mangrove ecosystems.
