Santa Maria / Santiaguito volcano (Guatemala), activity update: moderate explosions at intervals of 15 minutes
Santiaguito volcano in Guatemala has been displaying a slightly elevated state of activity in recent days. INSIVUMEH reports moderate explosions about every 15 minutes that eject plumes of gray ash tot 600 and 800 meters above the crater, and producing an ash plume drifting to the west and SW until dissipating at about 15 km distance.

Light ash falls from these eruptions frequently occur in the villages San Marcos, Buena Vista and Palajunoj and the El Faro, Florida, and Monte Claro Fincas.
Crater glow at the summit of the lava dome is well visible at night, and a blocky lava flow with constant avalanches of blocks rolling down to tits base continues to be active, raising secondary ash plumes.
The monitoring network records the explosions on seismic signals.

Moderate explosions continue producing small gray ash columns, and ashfall in the areas of the nearby farms to the west. Weak avalanches occur from the front of the small active lava flow on the southeast side of Santiaguito. ... read all

Santa María / Santiaguito volcano (Guatemala) activity update: lava flows on S and SE flanks, moderate ash explosions with plumes up to 700 m high
INSIVUMEH reported that active lava flows on the S and SE flanks of Santa María's Santiaguito lava-dome complex generated block avalanches on 27 and 30 January. Moderate explosions generated ash plumes that rose 700 m above the complex and drifted SW and S. Strong winds caused re-suspended ash to rise 1 km high and drift several kilometers W and S. Ashfall was reported in Monte Claro (S) and Palajunoj (SW) on 27 January. read all

Santiaguito volcano (Guatemala) activity update: sporadic explosions, continuing lava dome growth, small lava flow on SE flank
The lava dome growth of Santiaguito continues at moderate levels. Sporadic explosions produce ash clouds that rise up to 600-800 m above the lava dome and mostly drift SW. A viscous lava flow is active on the SE flank. Block avalanches are generated from the front of the lava flow and on the SW flank, accompanied by rumbling noises. ... read all

During the month of January 2012 the activity of the volcanic dome of Santiaguito Caliente has been steady with many degassing emissions and ash plumes well above the top of the volcano Santa Maria (the volcano father). during the 4 days of observation of the activity by the team of geologists and volcanologists during an expedition to VolcanoDiscovery, we identified one to two hours by pyroclastic flow. These flows are formed by avalanches of ash and incandescent blocks produced during the surge in gas and magma during the extrusion of the dome and they ran down the sides of the South and South West dome to spread out up to 500 m to 1 km distance from the base of the dome. ... read all
