INSIVUMEH reported that on 9 August heavy rain triggered lahars that traveled down the Seca drainage on Fuego?s W flank and the Mineral drainage, carrying tree trunks and blocks as large a 2 m in diameter.
During 12-14 August weak-to-moderate explosions generated ash plumes that rose almost as high as 1 km above the summit and drifted W and SW.
Incandescent material was ejected 150 m high, and avalanches of blocks descended the Cenizas (SSW), Las Lajas (SE), and Santa Teresa (W) drainages.
Ashfall was reported in Santa Sofía (12 km SW), Morelia (9 km SW), Panimaché I (8 km SW), and finca Palo Verde.
