Shiveluch volcano this morning (KVERT webcam)
Klyuchevskoy (Kamchatka): The violent explosive phase of the eruption ended at 13:00 UTC on October 20. KVERT reported a decrease of the tremor from 150.4 mcm/s to 3.3 mcm/s and the cessation of ash emission that last reached 26,000 ft (8 km) altitude.
Santiaguito's Caliente lava dome yesterday morning
Lava flows continue to effuse on the south-west, south-east and west volcanic flanks.
Shiveluch (Kamchatka): The growth of the lava dome continues along with strong degassing/steaming and occasional explosions that produce ash plumes rising to up to 4-6 km altitude.
Popocatépetl (Central Mexico): No significant changes in (the currently weak) activity occurred. CENAPRED only recorded 5 weak emissions during 19-20 Oct.
Santa María / Santiaguito (Guatemala): An increase in effusive activity was reported. The observatory mentioned "abundant activity" from two lava flows on the western and southern flank of the Caliente dome, which generate block avalanches. Explosive activity has remained at normal, rather weak levels with infrequent ash explosions ejecting plumes of up to about 700 m height.
Pacaya (Guatemala): Near continuous, relatively strong strombolian activity is visible from Guatemala City. A plume of fine ash from this activity rises to about 2700 m a.s.l. and drifts to the S and SE.
Fuego (Guatemala): A trend of increasing explosive activity is visible over the past days. INSIVUMEH reports weak to moderate explosions with ash plumes rising up to 800 m above the crater and producing a plume drifting 10 km to the west and northwest.
Shock waves that rattle doors and windows and roofs in villages like Morelia, Panimache, Sangre De Cristo and others on the SW flank accompany these explosions.

Klyuchevskoy (Kamchatka): Strong explosive and effusive activity continues. KVERT monitors the situation closely and issues alerts every few hours. Last evening, ash emissions again reached almost 30,000 ft (8-9 km) altitude. "The ash plume this morning has decreased in height to 21,300-24,600 ft (6.5-7 km) a.s.l. but by now, an ash plume dangerous for aviation is extending about 736 mi (1188 km) to the south-east and east of the volcano (satellite data at 0135 UTC on October 19, 2013)." Video of last night's impressive activity with lava fountains and lava flows all over the flanks of the volcano: ... [more]

Klyuchevskoy (Kamchatka): VAAC Anchorage sent out a message shortly before midnight (UTC) that the "eruption has ended" based on the absence of ash emissions from satellite imagery and pilot observations. This followed a particularly strong explosive phase that apparently occurred last night, when seismic data suggested strong emissions and an ash plume rose to possibly 33,000 ft (10 km) altitude. Webcam images from last night showed strong glow from lava flows and summit activity, but today the volcano has been hidden in clouds and no direct views have been possible so far. ... [more]

Klyuchevskoy (Kamchatka): KVERT reported a small decrease in activity, although it seems during the past hours (after the report) to have increased again (see video below). The activity in any case can be considered high. An ash plume rises to up to 26,200 ft (8 km) a.s.l. and extends to the east-north-east of the volcano. ... [more]
