Santa María's Santiaguito lava dome has been very active during the past days and weeks. The strongest eruption in this period produced ash plumes that reached an altitude of ca. 5.3 km (17,400 km) a.s.l. on 15 November. Ashfall was reported from areas to the N. Lava flowed down the SW, S, and SE flanks of the Caliente dome.

According to the Washington VAAC, minor emissions from Santa María's Santiaguito lava-dome complex were visible on satellite imagery on 14 November. The small ash clouds drifted WSW.
According to the Washington VAAC, minor emissions from Santa María's Santiaguito lava-dome complex on 26, 27, and 30 October were visible on satellite imagery. The small plumes of gas and light ash drifted predominantly W.

Explosive activity at Santa María has continued to be reported during 21-29 September by INSIVUMEH. Two explosions on 21 September caused minor ashfall and small block avalanches. A pyroclastic flow the next day was generated by material coming off of Caliente dome.
Explosions at Santa María's Santiaguito lava-dome complex on 9 and 10 August produced gas-and-steam plumes with little-to-no ash content. These plumes reached heights of ~1.5 km above the summit (~17,300 ft a.s.l.) and drifted SW.
According to the Washington VAAC, on 1 July small ash plumes from Santa María's Santiaguito lava-dome complex reached altitudes of 5.8 km (19,000 ft) a.s.l. and drifted SW. On 3 July, INSIVUMEH reported that an ash plume reached ~800 m above the summit (~15,000 ft a.s.l.).

Explosions at Santa María's Santiaguito lava-dome complex on 17 April produced ash plumes that reached heights between 500 and 900 m above the volcano (14,000-15,300 ft a.s.l.). Several pyroclastic avalanches occurred that sent material down the volcano's S flank.

Santa Maria volcano's Santiaguito crater remains at elevated level of activity. Frequent ash explosions produce plumes reaching up to 3 km above the crater, and sometimes small pyroclasitic flows, decending the NE and NW flanks. Ash fall is frequent over the localities El Faro, Patzulín, La Florida and others.

A large number of weak-to-moderate explosions occurred at Santa María's Santiaguito lava-dome complex during 22-28 March, producing ash plumes that rose to ~1 km above the volcano (15,650 ft a.s.l.). The plumes drifted SW, depositing ash on properties 8-10 km away. On several days, short pyroclastic flows and block-and-ash avalanches descended the SW flank of Caliente Dome.

On 6 March around 0733, a moderate explosion at Santa María's Santiaguito lava-dome complex produced an ash plume and pyroclastic flows. A strong explosion later that day at 1025 sent an ash plume ~3 km above the volcano (or 22,200 ft a.s.l.) that deposited ash throughout the volcanic complex. The explosion was accompanied by pyroclastic flows that traveled down the volcano's NE and SW flanks.

Santa Maria's activity has somewhat decreased during the past weeks. Moderate explosions continue to form ash-loaden plumes of up to about 1 km height. Occasional small block and ash flows accompanied by loud noises detach from the southeast flank of the active lava dome. ...more on Santa Maria volcano

On 4, 6, and 7 March, satellite imagery showed small ash plumes emitted from Santa María's Santiaguito lava-dome complex. The plumes reached ~3 km (~10,000 ft) a.s.l.

Ash venting producing plumes of up to 1500 m and small incandescent pyroclastic flows from the east rim of the growing lava dome continue at Santa Maria volcano. The pyroclastic flows produce a lot of fine ash suspended in clouds of about 1 km height that can remain suspended for hours. The ash clouds are drifted mainly to the southeast.

Santa Maria volcano in Guatemala continues to be the most active volcano in Central America at this time. Ash explosions from the lava dome are occurring frequently and produce plumes of typically 300 - 1500 m height as well as pyroclastic flows descending from the crater of the Domo Caliente. These flows produce clouds of very fine ash that causes respiratory problems in the vicinities of the volcano. Ash plumes from the volcano are dominantly transported in SW directions.

Several explosions occurred at Santa Maria's Santiaguito lava-dome complex during 15-17 February, with ash plumes rising to ~1.5 km above the volcano (or 17,300 ft a.s.l.). Some explosions were accompanied by small pyroclastic flows that traveled SW and NE down Caliente dome. Avalanches of incandescent volcanic material spalled off of active lava-flow fronts.

Constant lava avalanches are observed from the active lava dome on its southeast and east side. Weak to moderate explosions produce ash plumes and ash fall up to about 12 km away from the summit, mostly to the south, in the area of the communities: El Faro, Patzulín, La Florida, Monte Claro y la zona de Palajunoj.

Volcanism continued from the Santiaguito lava-dome complex at Santa Maria during 18-24 January 2006. Intermittent ash explosions sent gray ash as high as 800 m (2,600 feet) above the crater, causing ashfall in some local communities. Avalanches of blocks and finer material from lava-flow collapses is constant on the S and SW flanks.
