Klyuchevskoy (Kamchatka): The effusive-explosive eruption at the volcano persists, characterized by two active lava flows on different slopes and vigorous strombolian eruptions from the summit crater.
The lava continues to ooze out from the summit vent, keeping the flow active along the Apakhonchich chute and relatively quickly advancing more than halfway to the base of the edifice. Emissions of fluid and incandescent lava on the southeastern flank have increased in length, currently about 3,77 km long. Glowing lava blocks frequently detach from the flow front, generating grey dust as it descends over the slope. Simultaneously, another active lava arm continues to erupt from the northwestern flank vent (so-called lateral eruption). This time, the lava flow along the southwestern Kozyrevsky channel appears inactive.

The Observatorio Vulcanológico y Sismológico de Costa Rica (OVSICORI) issued that three small phreatic eruptions and 23 steam-laden plumes appeared from the volcano over the past week. Phreatic explosions form when the ejecta consist solely of old country rock, indicating interaction between water and heated conduit-rocks rather than magma itself.
