Santiaguito volcano (Guatemala): increased lava flow activity
Sunday Nov 03, 2013 09:14 AM | BY: T
In recent days the eruptive activity has increased, in particular towards more effusive activity. The Caliente lava dome produced a higher rate of lava extrusion at the edges of the dome and explosions at a rate of approx. one per hour with ash plumes of up to 500 m drifting in westerly directions.

The volcano observatory warns that rapid accumulation of fresh deposits (lava flows and tephra) the risk of pyroclastic flows generated on the steep flanks of the dome is elevated, mainly on the east, south and western flanks.

An increase in effusive activity was reported. The observatory mentioned "abundant activity" from two lava flows on the western and southern flank of the Caliente dome, which generate block avalanches. Explosive activity has remained at normal, rather weak levels with infrequent ash explosions ejecting plumes of up to about 700 m height. [more]

The volcano is in its most typical state of activity. After a few days with less (recorded) activity, the volcano's lava dome has again produced a number of small to moderate explosions with ash plumes rising up to about 700 m yesterday. Glow was observed at the eastern rim of the Caliente dome, which suggests that slow lava extrusion has resumed there as well. [more]

No significant changes occurred over the past days. INSIVUMEH's volcano observatory reported two explosions this morning with ash plumes of about 600 m height, causing light ash fall in La Florida and parts of Monte Claro. No activity was observed at the lava flows on the dome's flanks. [more]

INSIVUMEH reported no explosions and no movements at the blocky lava flows on the dome's flanks, but heavy rainfalls inhibit detailed observations. Strong degassing is observed. [more]
