On 16 December the ash plume, generated by a large explosion, rose to a maximum height of 7 km and contained lightning. Other explosions generated ash plumes up to 2 km high. Satellite imagery showed ash plumes drifting 140 km NW, and 110 km NE at an altitude of 7.9 km a.s.l. The larger explosions during the morning were followed by pyroclastic flows that descended the SW and NW flanks.
On 17 December satellite images showed ash plumes drifting 50-130 km NE, and a dense ash plume drifting over 200 km NE at an altitude of 7 km a.s.l. IG noted that explosions continued to generate ash plumes, but with progressively decreasing ash content. Ash plumes drifted NNE and NE, causing ashfall in communities downwind.
On 17 Dec. people living on the slopes of the Tungurahua volcano were evacuated [6]
