INSIVUMEH reported that during 14-15 October explosions from Fuego produced shock waves that were detected nearby, rumbling sounds, and ash plumes that rose 700 m above the crater and drifted S. A small avalanche traveled S in the Santa Teresa drainage. Cloud cover prevented visual observations during 16-18 October; however, explosions and block avalanches were heard.
