Santiaguito volcano (Guatemala): ash plume at 5 km altitude
Tuesday Mar 19, 2013 14:45 PM | DOOR: T
A phase of increased ash emissions or a relatively large seems to have taken place at Santiaguito today (INSIVUMEH will likely report about this in tomorrow's report). VAAC Washington alerts about an ash plume at 16,000 ft (about 5 km) altitude drifting east from the volcano.
If the altitude is right, the eruption column reached 2.5 km in height above the dome, more than twice as much as during the larger "normal" explosions regularly observed.

No significant changes occurred. Explosions of small and moderate size up to about 1 km height continue frequently and produce an ash plume drifting 15 km to the East and Northeast. Ash fall occurred in some parts of the city of Quetzaltenango where also faint odor of sulfur was noted. The lava flows on the sides of the dome remain active as well. [meer...]

The rate of explosions seems to have increased,- INSIVUMEH mentions "abundant" small and moderate explosions with ash plumes rising up to about 1 km above the dome and drifting 13 km to the west. Effusive activity continues as well, with moderate near constant block avalanches from the several active flows on the dome's flanks. [meer...]

Light ash fall occurred during the night in the ranches Faro and Florida. The dome continues to show both relatively strong explosive and effusive activity. ... [meer...]

The dome has been becoming more active, INSIVUMEH details in its latest report. 40-60 small to moderate explosions have been occurring daily, producing a fine ash plume rising about 500-1000 m above the dome. 4 lava flows are active on the flanks of the dome, and produce near-constant avalanches and sometimes small pyroclastic flows.

Activity remains essentially unchanged, and overall low. Explosions (1-2 per hour) from the dome produce ash plumes up to about 800 m high, and the viscous block lava flows descending the sides of the dome produce weak to moderate avalanches. [meer...]
