INSIVUMEH reported that 7-18 explosions per hour were detected at Fuego during 8-12 November.
Ash plumes from the explosions rose as high as 1.1 km above the crater rim and drifted 8-20 km W and SW.
Ash fell in areas downwind including Morelia (9 km SW), Santa Sofia (12 km SW), Sangre de Cristo (8 km WSW), Panimaché (8 km SW), El Porvenir, Finca Palo Verde, and San Pedro Yepocapa (8 km NW).
Incandescent material was ejected 150-300 m high and caused avalanches that traveled far, reaching vegetated areas in multiple drainages.
Lava flows as long as 1.2 km advanced in the Ceniza (SSW) drainage, though lava-flow activity greatly decreased by 12 November.
