If the amazingly regular current activity continues, a new lava fountaining episode known as paroxysm is likely to occur, and expected by many, during the following night.

The amazing show at Europe's most active volcano goes on!
Following the amazingly regular pattern of paroxysms (fire-fountaining episodes) at almost identical intervals of around 35-48 hours, the 6th eruption in a row is now in full swing!
It seems to follow exactly the patterns observed during the previous events. Accompanied by increasing volcanic tremor, explosive activity from the New SE crater began to rise slowly this evening, and has now developed into tall, sustained lava fountains now reaching 500-700 m of meters in height, but still increasing!
Lava flows are traveling from the SE crater to the SW and East into the Valle del Bove, overlapping the previous ones.

After the extremely powerful paroxysm (lava fountaining episode) during the night 22-23 Feb, which came as the 5th in a row following very regular intervals many people around the world are probably wondering whether the volcano will continue this remarkable series of eruptions.
If the last interval is an indicator as to when to expect a new paroxysm, it might well be in the course of the next night - something volcanologists, but also thousands of nearby residents, volcano spotters, and many more people from all over the world via webcams are certain to follow closely.
Since the end of the most recent activity, Etna has returned to intermittent mild summit activity from at least 4 of its summit vents, and volcanic tremor levels, kindly provided in real time by the National Institute of Volcanology and Geophysics (INGV) in Catania, are currently low. When this changes, be prepared for another show of fire! What we don't know from the publicly available data is whether the volcano currently inflates, which would be an indication that the volcano is about to recharge itself. This leaves us with the fun to speculate!
Etna erupts lava fountains over 1000 m high

Once more, Etna produced a very impressive show of unsurpassed fireworks at night: The - awaited - 5th lava fountaining episode (known as paroxysm) occurred late at night and turned out to be particular violent, equal or even stronger than the previous one 48 hours earlier. It was the 5th in a row during a single week's time!

The events building up to the eruption were quite typical and similar to the previous paroxysms: at first, the until-then intermittent and mild strombolian activity from the New SE crater gradually picked up, starting from around 10 pm local time. At the same time, volcanic tremor started to show a steep increase, sign of magma moving upwards inside the volcano's conduits.
The activity began to turn into sustained lava fountains from around midnight, and continued to increase in intensity. Around 00:30, the activity reached its peak phase with very tall lava fountains surpassing 1000 m height! An impressive eruption column of ash and steam rose to probably more than 10 km altitude and spread into an impressive, near-circular umbrella cloud towering over eastern Sicily.
At around 1:05 am, activity quickly ceased, with a phase of reactivation during approx. 4.40 and 6 am, when a series of strong explosions occurred at the SE crater complex.
Similarly to the previous events, lava flows were erupted to the SW and the east of the New SE crater into Valle del Bove, reaching similar lengths as before.

New lava fountaining eruption underway, 5th in a row now

Yet another phase of lava fountaining, or paroxysms, is almost certainly about to start now. Volcanic tremor has started to rise sharply from low to now already high levels, and strombolian activity at the eastern vent of the New SE crater is becoming more and more intense and near-continuous.
The 5th paroxysm in a row and within a single week comes after a slightly longer interval, approx. 48 hours, than the very regular roughly 35 hours intervals between each of the previous four events.
Given that the last one was very intense compared to the first three, it might not be surprising. Maybe the time to recharge or reproduce the right conditions deeper below for a new gas-rich batch of fresh magma to start rising just took a bit longer.
When will be the next eruption?

Once more, about 35 hours have now passed since the latest lava fountaining episode (paroxysm) at the volcano. If the pattern visible as the volcanic tremor spikes continues, a new one could be expected to start in the coming hours...
