June-July ash plumes reported by pilots may be the first eruptions in 122 years

The Darwin Volcanic Ash Advisory Center (VAAC) provided a series of pilot reports on Leroboleng. Confirmation from observers on the ground are pending.

At 1038 on 26 June 2003 aviators reportedly saw an ash plume rise to ~1.8 km altitude. An aircraft crew advised that the activity appeared to be increasing. Ash was not visible on satellite imagery. Another report stated that an ash plume was visible above Leroboleng at 1606 on 14 July at ~2.5 km altitude. Ash was not visible on satellite imagery and at that time VSI personnel could not observe the volcano. An alleged eruption on 29 July at 0900 lasted 10 minutes and sent an ash cloud to ~7.3 km altitude.

Photo Gallery


The summit of Leroboleng volcano contains 29 small fissure-controlled craters, two containing lakes; a small lava dome occupies one of the craters. Leroboleng volcano is also known as Lereboleng or Lewono and lies at the eastern end of a 4.5-km-long, WSW-ESE-trending chain of three volcanoes straddling a narrow peninsula in NE Flores Island. Most of the craters originated along three N-S-trending fissures immediately east of the summit of the volcano.
