Global Volcanism Program | Image GVP-00889

Colo volcano, seen here in eruption in September 1983, forms the isolated island of Una-Una in the Gulf of Tomini, northern Sulawesi.  The broad, low island is truncated by a 2-km-wide caldera.  Only three eruptions have taken place in historical time, but two of those, in 1898 and 1983, caused extensive devastation over much of the island.
