Fuego (Guatemala) - Report for 10 October-16 October 2018

INSIVUMEH and CONRED reported that on 12 October a new phase of activity began at Fuego, characterized by lava fountains rising as high as 400 m above the crater rim, avalanches of incandescent material down the W and SSW flanks, increased rumbling, and a lava flow traveling 1 km down the Santa Teresa (W) drainage.
Very frequent explosions generated ash plumes that rose 850 m and drifted 12 km S and SE.
On 13 October a steaming lahar descended the Ceniza (SSW) drainage, carrying blocks up to 2 m in diameter, and branches and tree trunks.
During 13-16 October explosions (8-18 per hour) produced ash plumes that rose almost 1 km and drifted 8-12 km S, SW, and W.
Ashfall was reported in areas downwind including Sangre de Cristo (8 km WSW), Finca Palo Verde, and Panimaché I and II (8 km SW).
Incandescent material was ejected 150-200 m high, causing avalanches of material within the crater, though some of the avalanches traveled long distances, reaching vegetated areas.
The lava flow on the W flank was still visible but by 14 October no longer active.
