Below is a summary of eruption dates and Volcanic Explosivity Indices (VEI).

The following references are the sources used for data regarding this volcano. References are linked directly to our volcano data file. 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. Additional discussion of data sources can be found under Volcano Data Criteria.

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.
