INSIVUMEH reported that during 13-14 June explosions at Fuego generated shock waves detected within 10 km, and block avalanches descended the Ceniza (SSW), Taniluyá (SW), Santa Teresa (SW), and Trinidad (S) ravines.
On 18 June heavy rain triggered a 20-m-wide, 1.5-m-deep lahar that traveled down the El Jute (SE) ravine, carrying tree trunks and blocks as large a 2 m in diameter.
Explosions during 18-20 June produced ash plumes that rose as high as 950 m above the crater and drifted 8-12 km S, SW, and W.
Ashfall was noted in areas downwind including Morelia (9 km SW), Santa Sofía (12 km SW), Finca Palo Verde, El Porvenir (8 km ENE), Sangre de Cristo (8 km WSW), and Panimaché I and II (8 km SW).
Incandescent material was ejected 100-200 m above the crater rim, and caused avalanches of material that traveled into the Ceniza, Taniluyá, Trinidad, and Santa Teresa drainages.
