Rabaul caldera is seen here in 1984 beyond the sulfur-coated walls of Tavurvur crater, located on a post-caldera cone on the NE side of the caldera. Matupit Island lies across Greet Harbor, and the flat-topped Vulcan cone appears on the opposite side of the caldera below the low western caldera rim.
