During 30 July-5 August, INSIVUMEH reported weak to moderate explosions at Fuego with incandescent blocks expelled 100-200 m above the crater accompanied by minor gray ash 300-400 m above the crater that drifted S. Shock waves from those explosions produced rumbling that rattled structures up to 4 km from the volcano. On most days, weak to moderate avalanches of blocks moved down the flanks towards Taniluya, Ceniza and Santa Teresa canyons.
No significant changes in activity have occurred at the volcano. The observatory reported 8 weak and one moderate strombolian-type explosion since yesterday.

During 23-29 July INSIVUMEH reported moderate to strong explosions at Fuego, with incandescent blocks being expelled 100-200 m above the crater accompanied by moderate to dark gray ash 400-600 m above the crater that drifted NW, W, and SW. On most days avalanches moved down the flanks. Columns, described as containing ash on 24 and 28 July, rose 4-4.6 km (13,100-15,100 ft) a.s.l. and drifted 8-12 km NE, NW, W, and SW.

Yesterday's new lava flow was no longer active today. Explosive activity has been weak to moderate today.
Mon, 14 Jul 2014, 17:42
A new lava flow is active on the southern upper slope of the volcano. It had a length of 400 m this morning, INSIVUMEH reported. Glowing rock avalanches detach from its fronts and reach the vegetation line.

During 30 June-14 July, INSIVUMEH frequently reported a white fumarolic plume rising from Fuego's summit extending up to 4,000 m (13,123 ft) a.s.l. Weak-to-moderate explosions generated ash plumes to similar heights during 30 June and 1, 4, 6, 7, and 9-13 July. Rumbling and jetting sounds often accompanied these explosions, often with durations of 1-5 minutes.

Fuego volcano yesterday morning (INSIVUMEH)
The latest lava flow seems to have stopped. The volcano remained in its typical persistent type of activity, with intermittent mostly weak to moderate strombolian explosions. Incandescent material was ejected to 50-100 m and ash plumes rose up to 400 m above the summit.

The new lava flow continues to slowly advance on the upper SE flank and reached a length of 200 m this morning. Strombolian-type eExplosions have been relatively frequent and weak to moderate in size, generating ash plumes up to 800 m tall.
Wed, 2 Jul 2014, 16:03
Activity has increase since last night. A new lava flow started to issue from the summit vent and traveled onto the SE slope towards the Trinidad canyon. This morning, it had reached a length of 150 m. Explosions have become stronger as well, generating ash plumes of sometimes more than 1000 m in height.

Fuego volcano this morning (INSIVUMEH)
No significant changes in activity have occurred at the volcano recently. It remains characterized by weak to moderate strombolian explosions every 1-2 hours on average, ejecting incandescent material to up to 150 m above the vent and producing ash plumes that rise 300-700 m.
Sat, 28 Jun 2014, 07:49
Activity has been relatively low recently. The volcano observatory only reported weak to moderate explosions with ash plumes up to 500 m height above the crater.
Wed, 25 Jun 2014, 06:00
INSIVUMEH reported that on 25-29 June weak to moderate explosions generated ash plumes that rose 500-800 m above the crater and drifted 10-12 km W, NW, and SE. Incandescent material that was ejected 100-200 m above the crater landed on the flank and formed avalanches. A lava flow from the crater moving SW towards the Tanilaya drainage generated avalanches into the Ceniza drainage (SSW).

Strombolian activity remains at moderate unchanged levels. Ash plumes rose to 600 m above the crater and shock waves from stronger explosions rattle roofs and windows in houses of nearby villages.

This morning's seismic signal from Fuego volcano (FG3 station, INSIVUMEH)
Activity is at moderate levels with frequent strombolian-type explosions that eject incandescent material to 100-150 m above the crater and produce ash plumes that rise up to 700 m. Jet-like degassing noises lasting 1-3 minutes accompany the explosions.

INSIVUMEH reported that, during 18-24 June, 7-23 explosions occurred per day at Fuego, generating weak-to-moderate ash plumes to 3,900-4,400 m (12,800-14,400 ft) a.s.l. and drifting with prevailing winds. The explosions during 17-18, 22, and 24 June were accompanied by rumbling sounds, some resembling jet engines that persisted for 1-5 minutes.

Activity at the volcano continued with little variation as intermittent strombolian explosions of small to moderate size. Incandescent material was ejected to about 100 m height and fell back to form glowing avalanches on the upper crater. Ash plumes rose to 400-700 m height and drifted for approx. 8 km before dissipating.

Seismic signal at Fuego volcano (FG3 station, INSIVUMEH)
Activity has decreased a bit. Strombolian explosions produced incandescent ejections to up to about 100 m and ash plumes rose to approx. 500 m.
Thu, 29 May 2014, 09:14
The lava flow has disappeared and explosive activity in turn increased. The observatory reported ash plumes up to 600 m high and drifting SW to 8 km distance. Shock waves accompanied the stronger explosions. Rainfalls triggered a lahar in the Las Lajas river canyon.

INSIVUMEH reported that during 31 May-1 June explosions at Fuego produced ash plumes that rose 350-550 m above the crater and drifted 8 km WNW. During the afternoon and evening of 1 June lahars descended the Las Lajas (SE) and Honda (E) drainages, as well as the Seca (W) drainage which disrupted traffic. Other sections of roadway to the W and S were also affected.

Fuego's lava flow yesterday morning
Activity increased at the volcano during Friday-Saturday. Near continuous mild to moderate strombolian explosions were observed and a new lava flow was erupted on the upper southern flank. Judging from the seismic signal, activity has decreased again today.

With the arrival of the rain season, INSIVUMEH warns of mud flows that will likely occur during heavy rainfalls remobilizing loose deposits that have accumulated in the canyons draining from the volcano. Such lahars are potentially very destructive and can reach and flood low lying areas on the south coast.
