Fuego News
The volcano showed a dramatic activity at 16:18 local time on 2 May.
A strong eruption culminated in a pumice-and-ash flow caused by an ash plume collapse. The pyroclastic flow raced down through the southwestern Ceniza gorge. Phoenix clouds, typical phenomena for pyroclastic flows, appeared to happen as billowing grey ash plumes separated from the torrent. Plumes reached approx. 16,400 ft (5,000 m) and extended about 40 km to the west-southwest of the volcano.
The reason for this flow was likely the accumulation of denser pyroclastic material in the ash column and its partial destabilization due to gravity. Pyroclastic flows are deadly, turbulent hot avalanche of lava rock fragments of all sizes embedded in a mixture of turbulent gas and ash racing down slopes.

Update May5:
This morning at 02.00 hrs, Fuego entered a new eruptive stage. A report published this morning at 05.10 hrs by the INSIVUMEH (Guatemalan Institute of seismology, volcanology, meteorology, and hydrology) stated this new stage was punctuated by a lava flow in the Ceniza Canyon, followed by constant incandescent activity and gas and ash emissions, forming avalanches to the south and southwest.
An additional report at 05.45 hrs noted a 5 km exclusion zone around the volcano and provided recommendations for the public on how to handle the increased volcanic activity. Recommendations included wearing a face covering to prevent inhaling ash and being aware of evacuation routes.
This morning, at 06.50 hrs, strong explosive activity produced an eruptive column of ash and gas that reached 5,500 – 5,800 m asl (1,737 – 2,037 m above the crater summit).
The violent ash explosion has produced pyroclastic flows extending town the Ceniza and Las Lajas canyons but it is possible pyroclastic activity could extend beyond these volcanic gullies. A pyroclastic flow is a hot and fast mixture of gas, ash, and blocks of rock that descends volcanic flanks.
At 09.45 hrs CONRED announced the closure of the RN14 road in two locations as a preventative measure.
As of 10.00 hrs, pyroclastic flows have also reached the Seca and Santa Teresa canyons, situated on the western volcanic flank. The eruptive column is now over 6,000 m asl (2,237 m above the crater summit)and has spread over 70 km, expected to reach over 100 km within the next six hours, over 7.5 million people live within this radius.
