A large explosion on 2 October at 2252 deposited a light dusting of ash in about a 15 km2 area around the volcano. During the week of 9-15 October, white fume was continuously present above the crater, rising to heights of 300 m. During that week, about 13 tectonic and 11 volcanic events were recorded/day.
Geological Summary. 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.
