Volcano news: Santa Maria (Guatemala)

Santa María / Santiaguito volcano (Guatemala) activity update

Sunday Nov 24, 2013 09:40 AM | BY: T

No significant changes in activity occurred. Explosions generate ash plumes as high as 900 m above the dome and effusive activity continues to produce small lava avalanches mainly from the NE flank of the dome. A felt earthquake occurred yesterday night at 00:32 local time.

Santiaguito's Caliente lava dome yesterday morning
Tuesday, Oct 22, 2013
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]
