Small pyroclastic flow from Shiveluch on 30 Dec 2012
Activity at Shiveluch has been relatively calm, but the slow extrusion of the lava dome inside the crater continues as incandescence and occasional explosions, but also occasional rockfalls and associated weak pyroclastic flows show. As our French colleagues from activolcans noticed, a small partial dome collapse occurred last night at 21h54 local time and produced a pyroclastic flow that traveled almost 1 km through the ravine at the base of the active dome.
Mi, 26. Dez 2012, 06:00Based on visual observations and analyses of satellite data, KVERT reported that during 21-28 December a viscous lava flow continued to effuse on the NW flank of Shiveluch's lava dome, accompanied by hot avalanches, incandescence, and fumarolic activity. Satellite imagery showed a daily thermal anomaly on the lava dome. The Aviation Color Code remained at Orange.
