Volcano news: Santa Maria (Guatemala)
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....more
The Santiaguito lava dome remains moderately active, producing near-constant, small glowing avalanches at the SW side of the dome, and occasional small explosions producing ash and steam plumes of 0.4-1.2 km height....more
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.
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
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.
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....more
During the past weeks, weak-to-moderate explosions continue to occura Santa María's Santiaguito lava-dome complex, producing plumes that rose to a maximum height of 1 km above the volcano (or 15,650 ft a.s.l.). Occasionally, small pyroclastic flows are produced from the Caliente Dome descending the dome's S,E, and W sides.
