The St. Andrew Strait volcano is located in the Admiralty Islands north of Papua New Guinea. The volcanic complex consists of a series of overlapping Quaternary cones formed by rhyolitic lava flows and pyroclastic deposits on Lou and Tuluman Islands. Volcanism is aligned along a curved arc, extending through the 12-km-long Lou Island. Tuluman Island, seen here from the SW with Lou Island 1.5 km away at the upper left, was formed during a 1953-57 eruption.
