Etna volcano update: New lava fountaining eruption underway, 5th in a row now

Intense strombolian activity at the eastern vent of the New SE crater
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.

Etna volcano update: 4th lava fountaining eruption within 5 days comes at remarkable same interval since previous
The 4th paroxysm within little more than 4 days is occurring at the time of this update! Starting in the evening of 20 Feb 2021, the explosive activity at the New SE crater gradually increased and developed into sustained lava fountains now approx. 300 m tall, and still rising. ... alles lesen

As the same time interval (approx. 35 hours) as between the past 3 lava fountaining episodes or paroxysms has now passed since the last eruption yesterday morning, it is now a guessing game whether Etna is now heading to produce the 4th in a new series. ... alles lesen
