Explosions and ash columns at Santiaguito volcano in Guatemala [1]

A small eruption cloud was observed at Santiaguito volcano in Guatemala on January 11, 2013. INSUVIMEH [3] reported  explosions at cone crater, accompanied by steam plumes and fine ash columns up to 3300 meters,  moving west-southwest. 4 lava flows from the lava dome were observed and some stronger explosions with occasional small pyroclastic flows.

INSIVUMEH reported that during January 2-3 explosions from Santa María’s Santiaguito lava-dome complex produced plumes that rose 300 m. During January 2-4, the lava-flow front on the S flank was incandescent because avalanches exposed the hot interior. A weak explosion was detected on January 4. Explosions during January 5-8 produced ash plumes that drifted west and south-west. 

Moderate volcanic activity remained at Fuego and Pacaya volcanoes.
