Sheveluch volcano (Kamchatka): small pyroclastic flow triggered by rock falls from dome

Source: Volcano Discovery - 12/31/12, By T

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.
 

Webcam images also give evidence that from time to time lahars are generated in the same ravine.
