Satellite detected thermal signals and webcam incandescence continue from Tolbachik Volcano, December 17, 2012

Satellite based Mid and Thermal infrared signals highly elevated from ongoing activity at Tolbachik volcano. Near saturation in the thermal (AVHRR channel 4) data shows a large hot target, from the effusing activity and lava flow on the surface.

View from webcam shows incandescence is making plume highly reflective
