Tungurahua, Ecuador

The IG reported that, although cloud cover occasionally prevented visual observation during 24 February-3 March, ash plumes from Tungurahua were seen and rose to altitudes of 5.5-10 km (18,000-32,800 ft) a.s.l. The plumes drifted in multiple directions. Ashfall was reported almost daily in areas to the SW, W, NW, N, and NE. Blocks were sometimes seen or heard rolling down the flanks, and roaring or explosion noises were noted. Strombolian activity at the summit was observed at night on 24 and 25 February. On 25 February, explosions caused the ground and large windows to vibrate. An explosion on 1 March was followed by an ash plume that rose to an altitude of 10 km (32,800 ft) a.s.l. and drifted NW. Incandescence at the crater was noted at night on 2 March.

According to a news article from 3 March, ash covered at least 250 hectares of cropland, and additional land for cattle grazing.
