On 6, 8, and 10 February, INSIVUMEH reported that multiple explosions from Fuego produced ash plumes that rose to altitudes of 4.1-5.4 km (13,500-17,700 ft) a.s.l. and drifted S and SW. Ashfall was reported in areas downwind. Some explosions produced rumbling sounds and constant avalanches of blocks descended the flanks. On 8 February, explosions were accompanied by shock waves that were detected 10-15 km away.
