The paroxysm at Fuego, which had reached its peak phase during the night of Thu-Fri (28-29 July) has ended. Starting from the early afternoon yesterday (local time), activity gradually decreased and the volcano's activity has by now returned to intermittent smaller strombolian explosions.

The lava effusion dropped as well. As of yesterday evening, the two lava flows on the SE side were still active and 1500 m long while explosions at the vent were still reaching 400 meters height; by this morning, the lava flows continued to be active, but had decreased to a few hundred of meters length and are probably going to stop soon.

The recent paroxysmal eruptive phase (the 12th in 2016) with pulsating lava fountains and continuous ash emissions had lasted approx. 12 hours at its climax during the night 28-29 and morning of 29 July. It was described as one of the strongest so far this year.
This is also reflected by the thermal heat signal measured via satellite and the fact that it generated pyroclastic flows on several sides of the volcano (by collapsing parts of the lava flows and/or ejecta from the summit). A relatively large one can be seen descending to the western foot of the volcano on the webcam image on the SW side from yesterday morning.
CONRED (Guatemala's Civil Protection) had declared Orange alert for the Yepocapa municipality.
Another indication of the strength of the eruption was the relatively large amount of ash emitted. The ash plumes during the eruption reached 15-20,000 ft (4.5-6 km) altitude, i.e. 2000-2500 meters above the summit and drifted to the west, where moderate to strong ash fall occurred in distances up to approx. 20 km.

Strombolian-type explosions have increased in size and frequency during the past days. Many of the explosions ejected lava bombs to several hundred meters above the crater and caused spectacular incandescent avalanches on the upper slopes. Lees alle

The 10th paroxysmal episode at the volcano in 2016 has come to an end and the volcano is now back to its normal state of intermittent mild to moderate strombolian explosions, ejecting incandescent material up to 100 m above the summit vents, at intervals of 1-2 hours on average. ... Lees alle

The 9th paroxysmal eruption in 2016 is in progress at the volcano: starting yesterday, explosions have become stronger and more frequent. As the magma output rate increased strongly, the explosions have turned into pulsating lava fountains and a lava flow began to travel down the Las Lajas ravine on the SE flank, currently reaching about 1200-1500 m length. ...
