Shiveluch volcano (Kamchatka): pyroclastic flow yesterday morning

KVERT webcam image showing the first pyroclastic flow at Shiveluch yesterdayThe activity of the volcano remains essentially unchanged at currently low to moderate levels. The slow growth of the lava dome continues as viscous (sticky) lava accumulates in the dome. A (small) part of the inherently unstable dome collapsed yesterday morning and generated a pyroclastic flow that traveled down the SW valley between the dome and the remnants of the 1964 collapse scar, which forms a horse-show shaped wall around the dome.
The flow reached approx. 1500 m length and was 300-400 m wide. A second flow of similar size occurred immediately after. The resulting ash plume rose approx. 1 km.

The effusive and explosive activity at the volcano continue at currently relatively low levels. Occasional small avalanches occur from the active dome, but little or no glow can be seen on night-time webcam imagery, suggesting that the effusion rate is at the lower end at the moment. [mehr]

The volcano's activity has been comparably low recently, but continues as viscous lava rises and accumulates at the active lava dome. A small collapse occurred yesterday evening, triggering a pyroclastic flow on the SW flank of the dome and producing an ash plume that rose to approx. 3.5 km above sea level. ... [mehr]

The lava dome remains active and continues to grow slowly although activity is currently rather towards the lower end of the volcano's long-term average. ... [mehr]
Shiveluch volcano (Kamchatka) activity summary 21-29 April 2016: continuing dome growth and explosions
Montag, Mai 09, 2016
KVERT reported that during 21-29 April lava-dome extrusion onto Sheveluch's N flank was accompanied by strong fumarolic activity, dome incandescence, ash explosions, and hot avalanches. ... [mehr]
Donnerstag, Mär 31, 2016
The extrusive-explosive activity of the volcano continues at moderate rate. Glowing avalanches from the active lava dome and strong degassing indicate ongoing magma supply. Occasionally, explosions and larger avalanches that turn into pyroclastic flows occur as well and generate ash plumes that rise several 1000 meters. ... [mehr]
