[Photographs taken on 31 August (figure 1) and] 4 September by astronauts on Space Shuttle mission STS-8 showed small, relatively diffuse plumes long emerging from Iliboleng. [The 31 August plume extended at least 40 km and the 4 September plume was roughly 50-70 km long.]
Geologic Background. Iliboleng stratovolcano was constructed at the SE end of Adonara Island across a narrow strait from Lomblen Island. The volcano is capped by multiple, partially overlapping summit craters. Lava flows modify its profile, and a cone low on the SE flank, Balile, has also produced lava flows. Historical eruptions, first recorded in 1885, have consisted of moderate explosive activity, with lava flows accompanying only the 1888 eruption.
