Santiaguito volcano (Guatemala): increased lava flow activity, small pyroclastic flows

The Caliente lava dome of Santiaguito volcano on 23 JanSince 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.
The volcano observatory mentions that during the recent months, activity had been elevated with 40-45 explosions typically in one day, and associated ash plumes reaching 500-900 m height.
The prevailing easterly winds cause frequent light ash fall in distances up to 10 km to the east, sometimes even in the city of Quetzaltenango.

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.

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. [meer...]

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. [meer...]

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. [meer...]

Activity remains essentially unchanged. Small to moderate explosions are occurring at rates of 1-3 per hour, producing ash plumes that typically rise 300-600 m. Extrusion of viscous lava feeds several active block lava flows on the upper slopes of the Caliente dome. Their activity can be seen as near-constant avalanches. [meer...]
