Iliboleng
Indonesia
8.342°S, 123.258°E; summit elev. 1659 m
All times are local (unless otherwise noted)
During July, white plumes continued to be emitted to 300 m above the peak. Several shallow volcanic earthquakes were recorded daily during early July. In late July, seismic activity had returned to low background levels.
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.
