INSIVUMEH reported that on 4 July there were rumbling noises from Fuego and the seismic network detected multiple explosions. A lava flow traveled 100 m W towards the Santa Teresa ravine. A lahar carrying blocks descended the Ceniza ravine to the SW. On 7 and 8 July, explosions produced ash plumes that rose to altitudes of 4-4.5 km (13,100-14,800 ft) a.s.l. and drifted S, SE, and SW. Incandescence at the summit was observed and constant avalanches of blocks from lava-flow fronts descended the W flank.
