INSIVUMEH reported that during 10-11 September explosions from Fuego generated ash plumes that drifted W and NW. Ejected material formed avalanches within the crater. On 10 September lahars that descended the Taniluya (SW) drainage were 15-20 m wide, 1-2 m deep, and carried tree trunks.
The lahars blocked roads in Panimache I and II (8 km SW), Morelia (9 km SW), and Santa Sofía (12 km SW) for two hours. The next day lahars descended the Las Lajas and El Jute drainages (SE); they were 30 m wide, 4 m deep, and carried 2-m-diameter blocks, branches, and tree trunks.

Explosions during 11-12 September produced rumbling sounds and ash plumes that rose 500 m. Incandescent material was ejected 100 m and formed avalanches on the crater rim. A 150-m-long lava flow was active in Ceniza (SSW) drainage.
During 12-13 September ash plumes from explosions rose 200-400 m and drifted W and NE. Avalanches from ejected material again formed around the crater. Explosions during 14-15 September generated ash plumes that rose 850 m and drifted 10-12 km W and SW.
The explosions produced shock waves that rattled structures in villages within10 km of Fuego. Block avalanches descended Ceniza drainage. During 15-16 September explosions generated ash plumes that rose 550 m and drifted SW, and ejected incandescent material 75-100 m high.
Ash fell at the observatory.
