Kamchatka’s volcanoes continued with ongoing eruptions. KVERT reports that there are currently seven active volcanoes (orange alert) – Kizimen, Karymski , Shiveluch and Plosky Tolbachik at orange level and Bezymianny, Gorely and Klyuchevskoy at yellow level. Explosive-effusive eruption continues at Tolbachik with fluid lava continues to effuse from the southern fissure and the flows advance on the southwestern flank of the volcano. Plumes of steam and some ash continue to reach up to about 4 km (13,000 ft) altitude.
Strong seismicity of the volcano was registered with volcanic tremor amplitude reached 7.6 mcm/s. A big thermal anomaly was observed on satellite images at the northern area of Tolbachinsky Dol. Moderate seismicity was registered at Shiveluch. Moderate seismic activity was also registered at Kizimen volcano. A new lava flow extrudes from the summit on the north-eastern flank of the volcano with incandescence of the volcano summit, hot avalanches and strong gas-steam activity.
