Previous news
Santiaguito volcano this morning (INSIVUMEH)
Tuesday, Nov 26, 2013
The INSIVUMEH observatory reports weak to moderate explosions with ash plumes up to 700 m height and constant block avalanches from the rims of the Caliente lava dome, sign that effusive activity has increased somewhat. [more]
Sunday, Nov 24, 2013
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. [more]
Explosion at Santiaguuito yesterday morning
Friday, Nov 22, 2013
A phreatomagmatic (water-magma interaction driven) explosion yesterday morning produced a plume of fine ash rising to 3.2 km altitude (700 m above the lava dome) and drifted SE, causing ash fall in Finca La Florida. [more]
Wednesday, Nov 20, 2013
No significant changes in activity have occurred over the past days. INSIVUMEH reports weak explosions and continuing incandescent block avalanches from the active lava flow on the NE side of the Caliente dome. [more]
