Gorely (Southern Kamchatka): KVERT has no seismic data due to technical problems. The volcano continues to produce strong degassing, but has not erupted.
Klyuchevskoy (Kamchatka): Activity remains strong. A small explosion this morning produced an ash plume rising about 700 m above the summit and drifting 50 km to the east. The lava flow remains active and can be seen on webcam images at night.
Kizimen (Kamchatka): Activity (extrusion of lava at the summit) continues, but has decreased recently, as incandescent rockfalls have become more rare. Seismic activity remains "moderate" (KVERT) and strong degassing can be seen. About a week ago, the prominent spine at the summit dome collapsed.
Karymsky (Kamchatka): KVERT reported an explosion that produced an ash plume rising to 5-6,000 ft (1.5-1.7 km) altitude and drifted 30 km ESE. Seismic activity is moderate and a thermal hot spot at the summit is visible on satellite data.
Shiveluch (Kamchatka): Activity continues at moderate levels with little changes. The viscous lava dome remains active and produces occasional small ash explosions and avalanches.
Tolbachik (Kamchatka): No seismic or surface eruptive activity has been recorded recently. The eruption can probably by now be regarded to be over, but KVERT maintains Aviation Color Code yellow.
Bezymianny (Central Kamchatka Depression): The strong seismic activity of nearby Klyuchevskoy volcano obscured the seismicity of Bezymianny, which likely remains active with slow extrusion of its lava dome. Video data showed a moderate gas-steam activity of the volcano (KVERT).
24 September 2013:
Klyuchevskoy (Kamchatka): Strombolian activity, strong degassing, and the effusion of a lava flow on the upper flank continue. The following video shows this activity over the past day:
Large volcanic eruptions with strong degassing in a location that happens to be directly under the path of the jet stream. Seemed obvious the moment I saw the video that this would be the explanation.
Not touching the rest. Just same old, same old conspiracy thinking.
