Powerful eruptionof Sakurajima on 21 Oct, producing a plume that reached 18,000 ft
Zhupanovsky (Kamchatka, Russia): A new explosive eruption started yesterday night (23 Oct). An ash plume was detected drifting at an estimated 16,000 ft (5 km) altitude and drifting ESE. At least 1 mm of ash have been deposited in the Nalychevo valley, a natural park between Zhupanovsky and Avachinsky volcanoes.

Zhupanovsky volcano lies about 70 km northeast of the capital of Kamchatka, Petropavlovsk-Kamchatsky, and had its last eruption in 1959.
It is a complex volcano composed of several overlapping cones aligned on a roughly east-west oriented axis. The new eruption comes from the same vent that has been also the site of all known historical eruptions, located west of the highest point of the volcanic massif.
Sakurajima (Kyushu, Japan): A phase of strong explosions during 20-21 Oct culminated with an eruption on 21 Oct that produced an ash plume rising to 18,000 ft (5.4 km) altitude (VAAC Tokyo).
Since then, the volcano has calmed down and had only smaller explosions.
Langila (New Britain, Papua New Guinea): A thermal hot spot and an SO2 plume are often visible on satellite data, indicating that the volcano is in eruption although the nature of its current activity is not known exactly.
The volcano, one of Papua New Guinea's most active, has often semi-persistent strombolian activity and sometimes lava flows.

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]
