Small explosion at Santiaguito on the morning of 28 Dec 2015
During our stay at / near Santa Maria volcano during 26-29 Dec, we observed only explosive activity at Santiaguito, but no signs of effusive activity (lava flows): no rockfalls or other movements were seen at the recently active lava flows or on the flanks of the dome itself, indicating that at present, no lava flows are active.

Explosion from Santiaguito this morning (image: Sismos en Guatemala @SismosGuate / twitter)
A phase of elevated activity has started at the volcano since 29 November. The largest event so far occurred this morning at 07:07 local time, when a strong explosion produced an ash plume that rose approx. 2-3 km and (probably) a small pyroclastic flow. Ash fall occurred in nearby villages and towns including San Marcos Palajunoj, and Finca La Florida. Read more... read all

Heavy rainfalls caused several lahars during the past days. The volcano continues to produce occasional small to moderate explosions from the active Caliente dome. Read more... read all

Pyroclastic flow from Santiaguito last Wednesday (INSIVUMEH)
Activity has picked up during the past days: a series of partial collapses from the Caliente lava dome has been generating small to moderately large (up to 4-5 km long) pyroclastic flows, the volcano observatory reported in its latest special bulletin.

Santiaguito's explosion yesterday morning
A stronger than usual explosion occurred yesterday morning at 08:43 local time, producing a plume that rose approx. 2 km above the lava dome and generated small pyroclastic flows. Read more...

Activity at the Caliente lava dome remains essentially unchanged. Some explosions produced ash plumes of up to 500 m height and the eastern blocky lava flow remains weakly active.

Activity from the volcano has been low recently. Occasional weak explosions accompany the slow effusion of a blocky lava flow descending on the eastern flank of the Caliente dome.

Incandescence from the active lava flow on the flank of Santiaguito's dome
Activity has remained similar to the previous months. Occasional small explosions from the dome and a continuing active lava flow on the southeast side of Caliente dome continue.

No significant change has occurred recently. The lava flow on the eastern side of the dome remains weakly active. Weak explosions occur from time to time.
