On 4 August BNPB reported that during the previous three days the Strombolian eruption at Raung increased in intensity. Ash fell in Sempu, Songgon, Glenmore, Gambiran, and Banyuwangi. On 4 August dense blackish gray ash plumes rose 800 m and drifted SE. Based on satellite-image and wind data, the Darwin VAAC reported that during 29 July-4 August multiple ash plumes rose to altitudes of 4.3-4.9 km (14,000-16,000 ft) a.s.l. and drifted as far as 240 km in multiple directions. The Alert Level remained at 3 (on a scale of 1-4), and the public was reminded not to approach the crater within a 3-km radius.
Intense ash emissions of Gunung Raung, combined with northwest winds caused a new closure of the international airport in Denpasar / Bali this August 7th.
Ash cloud was moving at 5,000 meters above sea level on 500 km towards SE Friday morning.
Virgin Australia and Jetstar have suspended their flights since Friday.
