Tungurahua volcano news & eruption updates:
Tungurahua volcano (Ecuador), activity update: moderate explosive activity continues, lahars & mudflows
Moderately strong explosions continue at Tungurahua volcano.
Ash plumes rose to altitudes of 6-9 km (19,700-29,500 ft) a.s.l. during 22-28 August and drifted mainly NW, W, and SW. IG reported noises resembling the sounds made by blocks rolling down the flanks were reported during 22-26 August and explosions rattled windows in surrounding areas, including Baños 8 km to the N, on 24 and 25 August. Ashfall was reported in nearby areas, especially to the NW, W, and SW, during 25-28 August. On 28 August, lahars affected W and NW drainages, the Pampas sector, and interrupted traffic on the route between Ambato and Baños. Incandescent blocks rolled down the flanks.

Tungurahua continues to be the most active volcano in South America. During the past week, near-constant explosive activity produced plumes that rose to altitudes of 7-10 km (23,000-32,800 ft) a.s.l. and drifted mainly W, NW, and N. Ashfall was reported from areas downwind and from areas SW within 8 km, on all days except 25 and 27 March.
Noises resembling "cannon shots" and blocks rolling down the flanks were heard on 21, 22, and 25 March; windows rattled as far away as 11 km N in Guadalupe. On 23 March, lahars traveled mainly down NW gorges and affected the roads between Ambato and Baños, and between Baños and Penipe.
Strong activity continues at Tungurahua. Loud cannon-shot like explosions were observed at Tungurahua volcano. IG reports ash plumes rising to 5-9 km (18,000-30,000 ft) altitude and drifting mainly to the NW and W, where ashfall occurred during 7-8 and 10-13 March. Incandescent bombs were seen ejected and rolling down the flanks during most of the explosions.... [more]
Seismic activity and strombolian activity at Tungurahua has been increasing since the evening of 23 February, 2007. Ash fall has been reported in the villages of Pillate, San Juan, Cotalo and Bilbao.

IG reported that during 21-28 November, emissions from Tungurahua produced ash and steam plumes that reached altitudes of 6-9 km (19,700-29,500 ft) a.s.l. and drifted predominantly NW and W. Ashfall about 1 mm thick was reported from areas 8 km WSW on 21 November and from areas 8 km W on 25 November.
During 26-27 November, Strombolian activity propelled incandescent material up to 600 m above the summit. Blocks rolled 2 km down the flanks. Lightning was visible in an ash plume that reached 7 km (23,000 ft) a.s.l. and ashfall was reported from areas 8 km WSW. On 27 November, an ash plume rose to 9 km (29,500 ft) a.s.l. and drifted W.
