Activity is dominantly effusive. The new block lava flow that had recently formed on the southern flank of the Caliente dome produces glowing avalanches. The other flows on the SE side remain active as well.
A constant steam plume rises from the dome to an altitude of approx. 3000 m a.s.l. and incandescence is seen at the dome at night.

Activity remains dominantly effusive. The lava flows from the dome are still active and generate frequent block avalanches, whirling up fine ash plumes. [more]
Wednesday, Dec 05, 2012
Strong degassing from the dome and a new blocky lava flow entering the notch at the upper crater rim left by the explosions last week were reported by INSIVUMEH. The new flow produces abundant block avalanches causing a fine ash plume drifting W and SW. [more]
Friday, Nov 30, 2012
In the recent days, Santiaguito has been producing a number of larger-than-average explosions that caused ash fall in the surrounding areas. Ash plumes from these explosions rose 1.5-3.2 km / 5000-10,000 ft above the lava dome and were sometimes accompanied by small pyroclastic flows. ... [more]
Thursday, Nov 22, 2012
The lava flows from the dome remain very active, INSIVUMEH reports. At 06:09 this morning, a moderate pyroclastic flow was triggered by collapsing material of one of the flow fronts on the SE side. [more]
Tuesday, Nov 20, 2012
The activity remains at low levels and mainly effusive. There are only few and small explosions and the lava flows from the dome continue to be weakly active. [more]
