Gorely (Southern Kamchatka): No changes in activity (strong degassing, moderate seismic activity) have occurred.

Klyuchevskoy (Kamchatka): The eruption continues with increasing strength from two locations, both at the summit vent, and at the flank vent between Klyuchevskoy and Kamen where a cinder cone is growing. Webcam images show violent strombolian activity and/or lava fountains at the summit vent, large lava flows on the NW, W and SW flanks and a continuous ash plume drifting to the SE (see video below).
KVERT reports strong seismicity with increased tremor (81.6 mcm/s amplitutde). Satellite data showed a big thermal anomaly over the volcano. Ash plumes extended 263 mi(425 km) to the south-east of the volcano.


Kizimen (Kamchatka): Extrusion of magma at the lava dome has been weak recently, but it remains active.

Karymsky (Kamchatka): Explosive activity of strombolian to weak vulanian type continues as evidenced by the presence of a ash plume that extended about 11 miles (18 km) east of the volcano yesterday. KVERT reports moderate seismic activity.


Shiveluch (Kamchatka): KVERT reports that the "growth of the lava dome continues - strong and moderate ash explosions up to 4-6 km a.s.l., fumarolic activity and incandescence of the dome summit, and hot avalanches accompany this process. Satellite data showed a thermal anomaly over the volcano."

Bezymianny (Central Kamchatka Depression): The nearby strong eruption of nearby Klyuchevskoy volcano obscures any seismic signal from Bezymianny, but according to KVERT, the lava dome remains active.

Sakurajima (Kyushu, Japan): After a couple of days with less violent and less frequent explosions, the volcano stepped up its activity again and produced a series of 6 eruptions yesterday alone, culminating in an explosion that sent an ash plume to 12,000 ft (3.6 km).
One of the eruptions during the night (in Japan, 15:22 UTC) is shown on these videos:

White Island (New Zealand): A moderate explosive eruption occurred at around 20:09pm NZDT last Friday, GeoNet writes. "The eruption lasted about 1 minute based on data from acoustic and seismic sensors, and was confirmed by subsequent analysis of web camera images during daylight hours." The Volcanic Alert Level was raised to Level 2 and the Aviation Colour Code to Orange.
"Observations from the web cameras show an explosive eruption producing an ash cloud column that expanded across the Main Crater floor. New mud deposited on the crater floor is evident in the web camera images from the crater rim this morning. The present activity is a continuation of the unrest observed at White Island for the past 15 months and hazardous eruptions of this type may occur with no warning. This eruption is larger than recent events and would have been life threatening to people on the island."

Veniaminof (Alaska Peninsula, USA): The eruption continues. Seismicity remains elevated but partially masked by storm noise. Satellite and web camera images are obscured by clouds, but it is likely that lava effusion and minor ash emissions continue.(AVO)

Popocatépetl (Central Mexico): No changes have occurred. The volcano produces 1-2 generally weak emissions of steam and sometimes ash on average per hour.

Reventador (Ecuador): Intermittent small to moderate ash explosions continue.

Tungurahua (Ecuador): Activity has been comparably mild with strombolian explosions of varying size, steam and ash emissions causing some ash fall in nearby areas.

Lightning inside the eruption cloud above Klyuchevskoy volcano (KVERT webcam)
Klyuchevskoy (Kamchatka): (11 Oct) We posted the following time-lapse video of the eruption this morning (or evening, in Kamchatka time). At 08:30 UTC (17:30 local time), a new vent opened in the saddle between Klyuchevskoy and neighboring Kamen volcano, producing a fountain of lava and ash rising to about 7 km altitude. The KVERT webcam even captured lightning during this eruption: ... Read all
