Stromboli (Eolian Islands, Italy): After the brief surge of activity during last week, the volcano has calmed down again to average levels.
Etna (Sicily, Italy): What started last night in fact evolved into a true paroxysm this time, with tall lava fountains and lava flows from the New SE crater. This is the first eruption of this kind after 9 months, and it will be interesting to see whether more follow (likely).
The strombolian activity progressively increased and merged into lava fountains at around 04h40 local time. A lava flow descended into Valle del Bove and reached about 2600 m elevation on the slope north of Sierra Giannicola Picola. The eruption ended rapidly by about 06h30.

This marks the first “true” paroxysm this year, very similar to the spectacular ones during 2011-12, but comparably weaker than these.
Tremor is rising and probably, this means that some strombolian activity is present in either New SE crater or Bocca Nuova, but visibility is poor due to bad weather.
Shiveluch (Kamchatka): A possible ash explosion sent ash up to 16,500 ft (5.0 km) a.s.l. KVERT registered moderate seismicity, but clouds obscured the view of the volcano.
Tolbachik (Kamchatka): KVERT reports no changes in the ongoing eruption, that continues to produce lava flows from the southern fissure.
Ambrym (Vanuatu): Strong SO2 emissions are visible on today’s NOAA satellite data. This suggests that the lava supply to the lava lakes inside the vents remains strong.
Tongariro (North Island, New Zealand): An increased number of earthquakes and possibly a weak tremor pulses appear on today’s seismic recording.
White Island (New Zealand): Continuous tremor remains high (although a bit lower than a few days ago) and earthquakes have started to reappear. So far, no recent updates have been posted by GeoNet.
Santa María / Santiaguito (Guatemala): Relatively frequent small to moderate explosions have been occurring today. The activity generated ash plumes rising up to 1-1.5 km above the lava dome and drifting at 13,000 ft (4 km) altitude to the NW.
Fuego (Guatemala): The volcano has calmed down and is back to its typical activity with occasional mild strombolian explosions, generating ash plumes rising 5-800 m above the crater.
Copahue (Chile/Argentina): The volcano continued to show a gradually decreasing trend of internal activity, is the conclusion of the latest bulletin SERNAGEOMIN published.
Weak seismic swarms continued to be registered mainly in the first week of February. A total of 331 seismic events were measured between 1-15 Feb. Degassing has been weak except on 5 Feb, when a gas plume rose significantly higher. – Volcano Discovery
