Volcano news: Santa Maria (Guatemala)

Santa María / Santiaguito volcano (Guatemala) activity update

Sunday Jan 26, 2014 11:27 AM | BY: T

Activity has remained essentially unchanged. The lava dome produces intermittent weak to moderate explosions (with ash plumes up to 500-700 m height) and abundant avalanches at the active block lava flow fronts, especially on the eastern and southeastern side of the dome. Collapses at these fronts can produce small pyroclastic flows.

The Caliente lava dome of Santiaguito volcano on 23 Jan
Friday, Jan 24, 2014
Since the morning of 23 Jan, the lava flow front at the SE rim of the Caliente dome has become more active and generated a series of collapses resulting in small pyroclastic flows that reached the base of the dome. ... [more]
Wednesday, Jan 22, 2014
Volcanic activity from the active dome remains more or less unchanged both explosive and effusive. The volcano observatory reports small explosions (on average 1-2 per hour), significant degassing, and weak to moderate block avalanches at the active viscous flows on the sides of the Caliente lava dome. [more]
Friday, Jan 17, 2014
The effusion of blocky lava from the deom has become weaker, evidenced by some avalanches from the southern and southeastern rims. Explosive activity seems in turn to be picking up. On average 2-3 explosions per hour are seen from the Caliente lava dome with ash plumes rising up to 800 m and often causing light ash fall in areas to the southwest. [more]

Wednesday, Jan 15, 2014
A moderate explosion occurred this morning at 06:18 local time, forming a grayish ash column 700 m high, moving southeast causing light ashfall on the Santa Maria volcano and in Villa San José. The main activity remains effusion of blocky lava mainly from the SE and SW rims of the Caliente dome, where constants weak to moderate avalanches detach from the flows. [more]
Monday, Jan 13, 2014
The volcano's activity has remained essentially unchanged. Small explosions, intense degassing and viscous lava extrusion, especially on the NE side of the Caliente dome were reported this morning. [more]
