Ash seen in satellite imagery at 0613 on 2 August was rising up to 7-8 km (23,000-26,200 ft) a.s.l. and drifting 50 km E. Additional satellite data from 4 August at 0432 showed ash reaching up to 7.5 km (24,600 ft) a.s.l. and extending for 50 km to the NE. Two lava flows were reported on 4 August effusing down the W and SE flanks, with ash rising up to 7 km (23,000 ft) a.s.l. and drifting for 600 km to the SE.
