PVMBG reported that the eruption at Raung was ongoing during 16-23 July. Ash plumes rose 2 km and incandescence at the crater was visible. Seismicity fluctuated but remained elevated. 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.
Based on PVMBG information, and satellite-image and pilot observations, the Darwin VAAC reported that during 22-28 July ash multiple ash plumes from Raung rose to varying altitudes of 4.3-5.2 km (14,000-17,000 ft) a.s.l. and drifted as far as 400 km NW, W, SSW, S, and SSE. A news article from 29 July noted that 18 flights at most had been canceled during the previous few days due to the ash plumes, and that the Notohadinegoro Airport (2,100 km SW) had been temporarily closed.
