Santiaguito volcano (Guatemala) activity update: sporadic explosions, continuing lava dome growth, small lava flow on SE flank
Thu, 19 Jan 2012, 00:01 | BY: T
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. - All news about: Santiaguito volcano

Santa Maria volcano (Guatemala) - Smithsonian / USGS Weekly Volcanic Activity Report for 18 January-24 January 2012 (Continuing Activity)
INSIVUMEH reported that active lava flows on the SE flanks of Santa María's Santiaguito lava-dome complex generated block avalanches during 18-19 and 23 January. On 19 and 23 January explosions generated ash plumes that rose 400-800 m above the complex. On 19 January ashfall was reported in communities of La Florida (5 km S), Palajunoj (SW flank), and San Marcos (46 km NW). ... Read all

Santiaguito Volcano (Guatemala): update of activity: Eruptions of ash plume and pyroclastic flows
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. ...
