The small, 3.5-km-wide forested island of Blup Blup contains lava flows with well-defined flow fronts. A weak thermal area is located on the west coast, and another on the north coast. Most eruptive activity at the andesitic-dacitic volcano originated from a thickly wooded summit crater about 800 m in diameter, although a lava dome may be present on a ridge to the west, and a small satellite cone occurs along the SW coast. Reports of eruptions during historical time are erroneous, but the island may have erupted during the Holocene (Johnson 1990, pers. comm.). Blocks from a submarine debris avalanche lie to the NE of the island.

Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.



Synonyms
Garnot Island
The small island with the irregular shoreline at the upper left is Blup Blup. This 3.5-km-wide forested island contains lava flows with well-defined flow fronts, and a weak thermal area is located on the west coast. No historical eruptions have occurred, but the volcano may have been active during the Holocene. Blup Blup is part of the Schouten Islands, along with Kadovar volcano (the small circular island to the south, above the prominent sediment plume at the lower left) and Bam volcano (right).

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
