INSIVUMEH reported that explosions from Fuego during 13-14 August generated ash plumes that drifted 10 km W and SW. Three lava flows were active; one of the flows traveled SW. Five explosions during 14-15 August ejected incandescent material 100 m high, and generated ash plumes that rose 300 m and drifted 6 km.
Lava flows were 150 and 300 m long in the Taniluya (SW) and Ceniza (SSW) drainages, respectively. The next day explosions produced ash plumes that rose 550 m and drifted 10 km W. On 17 August 30-m-wide lahars carrying blocks traveled down the Las Lajas, Ceniza, and El Jute (SE) drainages.
During 17-18 August explosions that were heard generated ash plumes that rose 200-300 m and drifted 7 km W. Lava flows in the Taniluya and Ceniza drainages were each 400 m long.

During 18-19 August the flow rate increased; the lava flows were 600 and 800 m long in the Taniluya and Ceniza drainages, respectively. Incandescent blocks from the lava-flow fronts rolled down the flanks and reached vegetated areas. Explosions during 19-20 August ejected incandescent material as high as 150 m, and generated ash plumes that rose 400 m.
