Fuego volcano (Guatemala): increasing lava emission with pyroclastic flows

Pyroclastic flows in the Ceniza canyon this morning (INSIVUMEH)
A phase of increased lava flow activity occurred this morning from about 6 am local time, generating a series of pyroclastic flows that descended several ravines on different, but mostly the southwestern side of the volcano.

The volcano has been in moderate effusive activity for at least the past two weeks, feeding relatively small lava flows on the upper steep slope. A sudden increase in effusion rate seems to have caused the destabilization of the lava flows, generating rockfalls that turned into pyroclastic flows. The lava flows have quickly increased from previously 200 m to about 2 km length. The surge of magma supply is also suggested by the appearance of strong tremor pulses the previous night.
In the meanwhile, explosive (strombolian) activity from the summit vent has remained weak.
An ash plume rising as a by-product of the pyroclastic flows was reported to about 12,000 ft (3.6 km) altitude.

The lava flows were no longer active yesterday morning. Activity consisted in weak to moderate strombolian explosions with incandescent material projected to up to 150 m above the crater, and ash plumes of a few 100 m height. [more]

Activity has not seen significant changes over the past days. Mild to moderate explosions (14 during 26-27 Aug counted) produce ash plumes of 200-500 m height and weak to moderate glowing avalanches of bombs on the upper slopes. [more]

A surge in effusive activity has occurred overnight. The two active lava flows towards the Taniluya (western flank) and Ceniza (southern flank) canyons increased to 600 and 800 m length, respectively. ... [more]

A slight increase of activity has occurred over the past dayss. The INSIVUMEH volcano observatory reported 11 strombolian explosions during the past 24 hrs interval with plumes rising up to about 600 m above the crater, and incandescent fragments ejected to 100 m above the crater, creating avalanches on the upper flanks. ...
