Etna volcano update: New SE crater calms down, while central crater shows impressive fireworks
Residual lava effusion at New SE crater (l) and vigorous strombolian burst from Voragine (c) last night
After yesterday’s particularly long-lasting fire fountaining eruption from the New SE crater, activity had dropped back to similar levels as before.
Weak lava effusion, as well as secondary lava flows from sliding hot material on the steep slopes of the crater continued from the eruptive fissure of the New SE crater during the rest of the day and part of the night, but gradually died down.
Seemingly unaffected by the activity of its younger neighbor, the central summit crater Voragine has continued to show sometimes strong strombolian explosions at intervals ranging from 5-10 minutes. Judging from our visual impression over the past few days, this activity appeared to have increased since yesterday.
Whether or not Etna is heading to another paroxysm in the near future remains open to speculation, but based on the currently still quite regular rhythm of so far 8 episodes in just two weeks, it seems rather likely that another one could be expected to occur in the next 1,2 days.

Klyuchevskoy volcano (Kamchatka): flank-to-lateral eruption continues; new cinder cone formed

The flank-to-lateral effusive-explosive eruption at the volcano continues at moderate levels on the northwestern flank.
A new cinder has formed around the NW fissure vents and continues to grow with current height of 54 m and width of 101 m.
Actively growing cinder cone generates a scoria (incandescent material ) that is ejected to an approximate height of 50 meters above the crater and causes phreatic explosions at the contact with lava, ice and snow in the area of Erman glacier.
A gas-steam plumes containing some amount of ash is extending about 3 km to the SE of the volcano with an altitude of 6,900 ft(2,100 m).
The advancing lava flow continues to emerge from the NW fissure vent that melted snow and caused lahars which traveled along the Krutenkaya river.
