8-9 March explosions from Santa María's Santiaguito lava-dome complex generated ash plumes that rose 800-1,000 m above the crater and drifted W and SW. Block avalanches descended the SE and NW flanks. Ashfall was reported in the communities of Loma Linda, San Marcos, and Palajunoj. During 11-12 March explosions generated ash plumes that rose 800 m above the crater and drifted 20 km SSW. Ashfall was reported at the observatory, on the El Faro and Patzulin ranches, and in the village of Las Marías. Lava flows continued to produce avalanches. ...mehr [alles lesen]

During 1-2 March, explosions from Santiaguito lavadome produces ash plumes that rose 800 m above the crater and drifted 20 km W and SW. Block avalanches descended the SW flank, and lava flows were active on the S, SW, and NE flanks. Based on analyses of satellite imagery, the Washington VAAC reported that during 3-4 March ash plumes drifted SW. On 5 March an ash plume rose to an altitude of 4.6 km (15,000 ft) a.s.l. ...mehr [alles lesen]

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. [alles lesen]

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. [alles lesen]

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.
