Tungurahua volcano (Ecuador): strong explosive (vulcanian) activity
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.
