Etna (Sicily, Italy): Etna had no less than 3 paroxysms (particularly violent brief eruptive episodes) with lava fountains, lava flows and tall ash plumes from the New SE crater within the past 20 hours (so far).
This marks a change from the previous 9-month period characterized by intermittent mild to moderate, but often long-lasting periods of strombolian activity.

With much likelihood, more paroxysms could be expected in the near future.
Shiveluch (Kamchatka): A small partial collapse of the active lava dome occurred last night at 23h45 (GMT) and produced a relatively small pyroclastic flow, followed by mud flows towards the ravine at the NE flank.
Ann ash plume rose to about 7000 m altitude, VAAC Tokyo reported.
Tolbachik (Kamchatka): The eruption continues with no changes reported by KVERT.
Grozny (Iturup Island): SVERT reported that a gas and ash plume rose to an altitude of about 3000 m on 16 February.
White Island (New Zealand): Elevated continuous tremor interspersed with earthquakes continue.
Popocatépetl (Central Mexico): A phase of increased degassing has been taken place today. This is likely caused by a surge in fresh magma supply.
Elevated activity is also visible on the recent seismogram.
Santa María / Santiaguito (Guatemala): Activity continues to be dominated by moderate explosions. Ash plumes rising up to about 700 m, causing light ash fall in nearby areas. The dome shows a 200 m high degassing plume and there is only relatively weak effusive activity at the lava flows on the dome’s flanks
Fuego (Guatemala): The volcano is back to its typical mild, but continuous activity. INSIVUMEH reports 6 weak strombolian explosions with ash plumes rising about 400 m and incandescent bombs ejected to 100-150 m height above the crater.
