In a special report INSIVUMEH noted that activity at Fuego had increased on 15 December. Lava flows were 500 m long in the Ceniza drainage (SSW), and their emission rate rate had increased. Blocks from lava-flow fronts reached vegetated areas.
INSIVUMEH reports 7 explosions during the past day with ash plumes up to 700 m height.
This morning's seismic signal from Fuego volcano (FG3 station, INSIVUMEH)
Activity has increased since yesterday. The volcano observatory reports strombolian-type explosions that eject incandescent material to 100 m and ash plumes to 500 m height. Shock waves and incandescent avalanches accompany the explosions. A new (but so far weakly alimented) lava flow has started to descent from the summit crater.
Fuego volcano yesterday morning
The observatory reports no significant changes. About 30-35 small to moderate explosions occurred during 3-4 Dec, often with strong shock waves that rattled windows and roofs in up to 6 km distance. Ash plumes rose to about 4.2 km altitude (500 m height) and produced light ash falls in W and SW directions (Morelia, Panimache and other villages). At night, incandescent avalanches from the crater are visible.

Small eruption from Fuego yesterday morning
No significant changes in activity have occurred. The volcano produces small to moderate strombolian-type explosions with ash plumes rising up to about 800 m. The lava flows are no longer active.
The lava flow on the upper southern slope was no longer active this morning (while it was still 100 m long yesterday). The volcano is back to its typical mild explosive activity from the summit crater with strombolian bursts generating ash plumes up to about 600 m high, sometimes accompanied by loud shock waves.
Activity has returned to normal levels, with weak explosions (ash plumes of 500-600 m height drifting W and NW). The lava flow towards the Ceniza canyon remains weakly alimented and had a length of 200 m yesterday.
Seismic signal of Fuego yesterday (FG3 station, INSIVUMEH)
A surge in activity occurred yesterday, with drastically increased numbers of strombolian explosions and lava effusions. The explosions generated ash plumes rising about 500 m and caused moderate ash falls in areas to the south and SW, mainly in the village of Sangre de Cristo.

Lava flows on Fuego on 19 Nov into Taniluya (left) and Ceniza (right) canyons
Two lava flows are active on the upper slopes of the volcano at the moment, to the Taniluya (south) and Ceniza canyon (SE). The effusive activity started on 11 Nov and increased on 18 November, reaching a length of 600 m. Constant avalanches detach from the flow fronts.

On 21 November INSIVUMEH reported that a recent Strombolian phase at Fuego decreased in intensity. Explosions generated ash plumes that rose 450 m and drifted W and SW. Ashfall was reported in Sangre de Cristo (8 km WSW).

Fuego volcano this morning
A new lava flow towards the Taniluya canyon (S side) started on 11 Nov and reached a length of 500 m this morning. Explosive activity at the summit has remained stable with occasional weak to moderate explosions ejecting ash plumes to up to 700 m height and producing sometimes loud shock waves.

On 18 November INSIVUMEH reported that during the previous week explosions from Fuego produced ash plumes that rose 450-750 m and drifted W and SW. Some of the explosions generated rumbling noises, shock waves detected within 15 km, and rattled structures in Panimaché (8 km SW), Panimaché II (8 km SW), Morelia (9 km SW), Santa Sofía (12 km SW), and Sangre de Cristo (8 km WSW). A 600-m-long lava flow was active on the SE flank, and block avalanches that descended the Ceniza drainage (SSW) reached vegetated areas.

Current seismic signal from Fuego volcano (FG3 station, INSIVUMEH)
The volcano observatory of INSIVUMEH reports an increase in activity today: A new lava flow started to descend on the southern flank towards the Trinidad canyon and currently has a length of 100 m. Another branch towards the Ceniza canyon is 50 m long. From both flow fronts, incandescent avalanches detach with run-out lengths of up to 500 m.

Current seismic signal from Fuego volcano (FG3 station, INSIVUMEH)
Weak to moderate strombolian activity at the summit craters continues with little changes. Ash plumes rose to up to 500 m above the crater and drifted about 10 km in westerly directions, where light ash falls occurred in San Pedro Yepocapa and the villages of Sangre de Cristo, Morelia, Panimaché. The stronger explosions produce often loud rumblings and incandescent avalanches on the upper slopes.

INSIVUMEH reported that on 4 November, there was an increase in moderate and strong explosions generating plumes of ash up to 4,500 m a.s.l. The plume extended 10 km and drifted S and SW. Rumbling sounds were strong enough to shake zinc roofs and windows in the towns of Panimaché, Morelia, and Panimaché II.

A trend of increasing explosive activity is visible over the past days. INSIVUMEH reports weak to moderate explosions with ash plumes rising up to 800 m above the crater and producing a plume drifting 10 km to the west and northwest.

Activity has decreased and shifted back to be mainly mildly explosive. INSIVUMEH reported a few explosions with ash plumes of about 300 m height yesterday. The lava effusion has decreased. The lava flow was still active yesterday morning, but only 150 m long.

Fuego volcano this morning (? - certainly not 28 Oct 2013)
After its brief surge in activity, the volcano has calmed down again a bit, but continues to produce strombolian explosions ejecting glowing lava to 50-75 m above the crater and feeding its lava flow on the southern flank. This morning, it had reached a length of 800 m, the volcano observatory reports.

Fuego and the active lava flows this morning
Activity has increased today, the volcano observatory reports in its special bulletin. The number and size of explosions rose and produced incandescent fountains of up to about 200 m and an ash plume rising about 1 km which drifted 8 km S and SW. Shock waves that rattled windows and roofs of houses in nearby villages accompanied the explosions.

Activity has decreased again to relatively low to moderate levels. The recent increase did not result in another paroxysm.

Seismic signal showing the increase of Fuego's activity this morning
In the past hours, activity has increased and might be heading towards another paroxysm. The frequency and size of explosions rose significantly and has been creating an ash plume about 1 km high and drifting 8 miles south and southwest. Many of the explosions generate shock waves, rattling roofs and windows of houses in the villages Panimaché, Morelia and Panimaché II.

Activity has been weak recently. The lava flows on the upper southern flank is still active, and was about 100 m long this morning, headed towards the Trinidad canyon. Explosions have been few and only produced ash plumes rising a few 100 meters.
