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.

Elevated activity continues at Santiaguito, as recent visitors and the latest reports from INSIVUMEH confirm. The Santiaguito lava dome has been producing frequent ash explosions with plumes to 700-800 m height and small avalanches and pyroclastic flows traveling down the eastern and southern flanks of Caliente dome.

Santiaguito volcano had 4 strong eruptions between 18:50 and 20:00 local time on 26 April, 2010. According to INSIVUMEH and local newspapers, the explosions from the lava dome produces ash plumes reaching 8-9 km a.s.l. Authorities closed the airspace around the volcano in a radius of 20 km. [mehr]

During our pilot expedition to the volcanoes of Guatemala in Dec 2009, Santigaguito lava dome was observed between 25-28 Dec. The lava dome produced ash eruptions roughly every 0.5-3 hours with plumes reaching up to 300-1000 m elevation. On one occasion, a small pyroclastic flow was observed travelling down on the SW side of the lava dome. [mehr]
