Tungurahua, Ecuador

IG reported that although visual observations were occasionally limited due to cloud cover, ash-and-steam plumes from Tungurahua were spotted and rose to altitudes of 6-8 km (19,700-26,200 ft) a.s.l. during 25 March-1 April. Ash plumes drifted SW, W, and NW and were intermittently produced by explosions; ashfall was reported in areas downwind during 25 and 27-28 March. On 25 March, explosions propelled incandescent blocks from the summit that fell onto the flanks. Explosions also vibrated doors and windows in areas as far as 13 km away on 26 March and produced an ash plume to an altitude of 4 km (13,100 ft) a.s.l. on 27 March.
