Simpson harbor, seen here from Rabaul Volcano Observatory overlooking the city of Rabaul in 1983, fills the NW part of 8 x 14 km Rabaul caldera. Matupit Island appears at the left margin of the photo, and Vulcan, the site of major eruptions in 1937 and 1994, is the low cone across the harbor at the right-center.
