A moderate explosion occurred this morning at 05:18 local time, sending an ash plume to 700 m above the crater and drifting SW, where light ash fall occurred in Finca La Florida and Parcelamiento Monte Claro. ...more

A lahar descended the valley of the Nimá I river at 13:30 h local time yesterday, caused by heavy rainfalls mobilizing pyroclastic deposits. The mud flow was about 30 m wide, dense, hot and stinking of sulfur, and carried large boulders (up to 3 m across).
Thursday, May 30, 2013
Activity has remained generally low, with occasional small to medium-sized ash explosions and small avalanches from the Caliente dome.
Saturday, May 25, 2013
Activity remains low. A moderate explosion occurred last night at 17:55 h (local time) erupting an ash plume rising 600 m and drifting SW and causing light ash fall in Finca La Florida and Parcelamiento Monte Claro. Otherwise, the dome is degassing and a few weak avalanches occurred from the lava flow on the southern flank of the dome.
Thursday, May 23, 2013
Activity has remained weak and dominantly explosive. Occasional explosions from the Caliente dome produce ash plumes rising up to about 700 m.
Thursday, May 16, 2013
Only relatively few and weak explosions occurred recently, some of which caused light ash fall in nearby areas. The lava dome is producing a degassing plume most of the time. No reports of activity at the stagnant lava flows.
Tuesday, May 14, 2013
Activity has been generally low recently, with infrequent small explosions and occasional small avalanches produced from the weakly active lava flows on the dome's flanks.
Monday, May 06, 2013
The lava dome has remained relatively calm recently with few and mostly weak explosions every now and then, and little activity from the blocky lava flows on the flanks of the Caliente dome.
Tuesday, Apr 30, 2013
Activity remains more or less stable, with occasional explosions from the lava dome producing ash plumes up to about 800 m high. Effusive activity in the form of avalanches from the blocky lava flows on the sides of the Caliente dome has remained relatively weak.

Monday, Apr 22, 2013
Explosions of moderate size have been observed producing ash plumes reaching up to 900 m height, and causing light ash fall in the areas of Finca El Rosario and near San Marcos Palajunoj. Strong degassing noises were sometimes heard and some avalanches occurred from the flows on the NE and S sides of the active lava dome.
Saturday, Apr 20, 2013
INSIVUMEH reports weak to moderate explosions producing dense gray ash plumes rising to up to 1 km above the lava dome and drifting west for more than 10 km. The lava flows have picked up activity as well and advanced within the gullies of Nima Nima I and II.
Sunday, Apr 14, 2013
Activity has been low recently. Few weak to moderate explosions continue to occur from time to time at the lava dome, with ash plumes reported 5-700 m high and drifting for about 10 km to the west.
Monday, Apr 08, 2013
Activity has remained weak with infrequent, mostly small explosions from the dome, and no or little movement at the lava flows from the Caliente dome.

Thursday, Apr 04, 2013
Activity has been low in recent days. The observatory reports that the lava flows have been calm today, and that only one weak explosion was heard (not seen due to mist hovering over the lava dome).
Tuesday, Apr 02, 2013
Explosive activity has been weak, but INSIVUMEH reports that the lava flows are producing constant avalanches, or in other words are well alimented at the moment. ...more

Wednesday, Mar 27, 2013
Activity remains more or less unchanged, but relatively weak. The volcano observatory reported to have heard 5 explosions during the past night, and notes ongoing weak to moderate avalanches from the active lava flows on the flanks of the Caliente lava dome. Fine ash fall has again occurred in the fincas El Faro and La Florida.
Tuesday, Mar 26, 2013
INSIVUMEH reports no significant changes in activity. The lava dome has been a little bit less explosive recently but continues to effuse blocky lava flows that descend its flanks and produce weak to moderate avalanches.
Friday, Mar 22, 2013
Activity at the dome has decreased compared to last week. INSIVUMEH reported only weak explosions with ash rising 400 m, and few and small avalanches from the lava flows today.
Tuesday, Mar 19, 2013
A phase of increased ash emissions or a relatively large seems to have taken place at Santiaguito today (INSIVUMEH will likely report about this in tomorrow's report). VAAC Washington alerts about an ash plume at 16,000 ft (about 5 km) altitude drifting east from the volcano. ...more
Monday, Mar 18, 2013
No significant changes occurred. Explosions of small and moderate size up to about 1 km height continue frequently and produce an ash plume drifting 15 km to the East and Northeast. Ash fall occurred in some parts of the city of Quetzaltenango where also faint odor of sulfur was noted. The lava flows on the sides of the dome remain active as well.
Sunday, Mar 17, 2013
The rate of explosions seems to have increased,- INSIVUMEH mentions "abundant" small and moderate explosions with ash plumes rising up to about 1 km above the dome and drifting 13 km to the west. Effusive activity continues as well, with moderate near constant block avalanches from the several active flows on the dome's flanks.
Thursday, Mar 14, 2013
Light ash fall occurred during the night in the ranches Faro and Florida. The dome continues to show both relatively strong explosive and effusive activity. ...more
Wednesday, Mar 13, 2013
The dome has been becoming more active, INSIVUMEH details in its latest report. 40-60 small to moderate explosions have been occurring daily, producing a fine ash plume rising about 500-1000 m above the dome. 4 lava flows are active on the flanks of the dome, and produce near-constant avalanches and sometimes small pyroclastic flows.
Tuesday, Mar 12, 2013
Activity remains essentially unchanged, and overall low. Explosions (1-2 per hour) from the dome produce ash plumes up to about 800 m high, and the viscous block lava flows descending the sides of the dome produce weak to moderate avalanches.
Friday, Mar 08, 2013
Activity remains similar to before. Moderate explosions from time to time produce ash plumes rising about 700 m altitude. ...more
Thursday, Mar 07, 2013
A slightly stronger than average explosion occurred earlier today, producing an ash plume rising more than 1 km above the dome and drifting SE.
Wednesday, Mar 06, 2013
The activity has remained more or less similar over the past weeks. Weak to moderate ash explosions from the dome occur 1-2 times an hour on average, with plumes reaching up to about 800 m above the dome. ...more
