INSIVUMEH reported that 5-15 explosions per hour were recorded during 13-20 July at Fuego, generating ash plumes as high as 1.1 km above the crater rim and shock waves that often rattled buildings around the volcano. Ash plumes mostly drifted 10-20 km NW, W, and SW and caused daily ashfall in several areas downwind, including Morelia (9 km SW), Panimachï¿½ I and II (8 km SW), Santa Sofï¿½a (12 km SW), El Porvenir (8 km ENE), Finca Palo Verde, Sangre de Cristo (8 km WSW), and San Pedro Yepocapa (8 km NW). Block avalanches descended the Ceniza (SSW), Seca (W), Trinidad (S), Taniluyï¿½ (SW), Las Lajas (SE), and Honda drainages, often reaching vegetated areas. Explosions ejected incandescent material 100-400 m above the summit during 13-19 July.
