Etna (Sicily, Italy): After little more than an hour with impressive fire fountains, the eruption quickly ceased and is now over. The lava flows to the south and east continue to descend, but may no longer be alimented.
The tremor signal started its rapid dive back to lower values as the supply of the just erupted batch of gas-rich fresh magma has been exhausted - until another one arrives from deeper reservoirs, maybe very soon...
...19 Feb:
About 45 minutes after the onset, the eruption is now at its peak, probably going to start to decrease soon.
An impressive eruption column is rising near vertically - thanks to only weak winds - from the New SE crater, to heights of estimated 20,000 ft (6.3 km) according to the latest bulletin of the Volcanic Ash Advisory Center (VAAC) of Toulouse. At altitude, it beautifully spreads into a near-circular cloud known as umbrella cloud.
...19 Feb:
UPDATE: the still ongoing paroxysm appears to be even more intense than its two predecessors and still not The height of the lava fountains is likely more in the range of 700 m, something which will be determined later by the volcano observatory.
The paroxysm should be at its peak now. Tremor is extremely high, similar to yesterday's event, and tall lava fountains up to 500 m are rising from multiple vents of the New SE crater.

...19 Feb:
The rate with which intensity increases is impressive. Within a few minutes since the onset, the lava fountains have already reached heights of approx. 300 m and still grow...
A tall ash and steam plume now rises several km above the crater.
...19 Feb:
Accompanied by steeply rising tremor, activity increases now by the minute.
The lava flow that had begun half an hour ago or so now increases and starts covering yesterday's flow. At the summit vent, explosions or small fountains are now visible as well.
...19 Feb:
Indications of a possible new paroxysm become stronger with the minute: lava flows have started to emerge from the summit vent of the New SE crater.
This is often a typical precursor to a lava fountaining episode and can be explained with new, gas-rich magma rising inside the conduits first pushing out the older degassed magma in the upper part of the conduits left from the previous episodes.
The situation is exciting!
...19 Feb:
Approx. 30 hours have passed since the last lava fountain episode or paroxysm at Etna, which followed after 30 hours after the preceding one.
In the past, Etna has been known for producing series of paroxysms at similar, surprising regular intervals. Obviously, the question now is whether the next one will follow this pattern or not. At the time of writing this post, tremor seems to be rising indeed, first sign that activity increases.

White Island (New Zealand): (19 Feb) A series of minor steam explosions from the active vent occurred at the volcano at about 02:20 local time today detected by seismic instruments as the volcano observatory GeoNet reported.
The overall series of pulses lasted for about 100 minutes and were of a similar size to those recorded on 29 Dec last year. Visibility of the explosions was limited due to dark.
