The eruption continues at full force. Here's the latest KVERT update:
Effusion of lava flows continues from the southern fissure at Tolbachinsky Dol. Very fluid lava is moving to the western side of Tolbachinsky Dol. A 5th cinder cone grows on the southern fissure above of Krasny cone.
Gas-steam plumes with ash rose up to 3-4 km a.s.l. and extended to different directions of Tolbachinsky Dol all week. A gigantic thermal anomaly was noting at satellite images in the northern area of Tolbachinsky Dol all week. A magnitude of volcanic tremor increased from 9 mcm/s on December 16, to 28 mcm/s on December 19, - probably, the explosive activity of the new cinder cone is increasing.
