The eruption at Semeru continued during 10-16 August.
The Darwin VAAC reported that during 13-16 August ash plumes rose to altitudes of 4.3-4.6 km (14,000-15,000 ft) a.s.l.
and drifted SW and W based on satellite images and wind models.
The Alert Level remained at 3 (on a scale of 1-4).
The public was warned to stay at least 5 km away from the summit, and 500 m from Kobokan drainages within 17 km of the summit, along with other drainages originating on Semeru, including the Bang, Kembar, and Sat, due to lahar, avalanche, and pyroclastic flow hazards.
