Fuego volcano (Guatemala) activity update: lava flow on east flank, occasional weak explosions, regular hissing-noise producing degassing

In a special bulletin on 3 August, INSIVUMEH reported a new phase of activity at Fuego, characterized by increased seismicity and degassing sounds. Incandescent tephra was ejected 200 m high and a lava flow traveled 500 m down the SW flank into the Taniluya drainage. Pyroclastic flows likely descended the SE and SW flanks. During 4-7 August explosions produced ash plumes that rose 200-400 m above the crater and drifted NW and W. Lava flows traveled 250-300 m down the Taniluyá drainage. Detached blocks from the lava-flow front traveled down the flanks to the vegetated area. Blocks also traveled down the Ceniza drainage (SSW). At night during 5-6 August explosions ejected incandescent tephra 100 m above the crater. ... Read all

INSIVUMEH reported that during 9-10 and 13-14 August explosions from Fuego produced ash plumes that rose 300-400 m above the crater and drifted NW and W. Degassing sounds were reported, and diffuse white plumes rose 100-150 m and drifted NE and NW. Lava flows traveled 200-250 m down the Taniluyá drainage (SW), generating block avalanches that reached vegetated areas. ... Read all
