archipelago off the northeastern tip of Celebes (Sulawesi), Indonesia. The islands extend northward from Celebes for about 160 miles (260 km) and have a total area of 408 square miles (1,056 square km); they are administered from Manado, the capital of Sulawesi Utara (North Celebes) provinsi (province). The main islands in the group are Sangihe, Siau, Tahulandang, and Biaro, and there are numerous islets. Tahuna (Taruna), on Sangihe's west coast, is the main town and lies in the shadow of Mount Awu (6,070 feet 【1,850 metres】), an active volcano to the north. Most of the islands' inhabitants profess Christianity. Manila hemp is grown, and its weaving is a major industry, but fishing and shipping are also important. Tourism (notably scuba diving) has grown in significance.
