Overview
The 2 x 3. 5 km forested island of Blup Blup contains lava flows with well-defined flow fronts. Weak thermal areas are located on the W and N coasts.
Most eruptive activity at the andesitic-dacitic volcano originated from a summit crater about 800 m in diameter, although there may be a lava dome on a ridge to the W and a small satellite cone along the SW coast. Reports of eruptions in 1616 and 1830 are erroneous, but there may have been eruptions during the Holocene (Johnson, 1990 p. c.
). Blocks from a submarine debris avalanche lie to the NE of the island.

About the Photo
The roughly 3.5-km-wide Blup Blup is north of the main Papua New Guinea island. The summit crater near the center of the island is visible in this August 2019 Planet Labs satellite image monthly mosaic (N is at the top). A small flank cone is on the SW coast and a submarine debris avalanche deposit is to the NE.
