Almost exactly 48 hours since the last lava fountaining episode (paroxysm), another one is occurring now at the volcano's New SE crater. This marks the 14th paroxysm in a row with almost identical intervals between since the start of the series in mid February.

The event followed very much the pattern observed during the previous episodes: Starting from 01:55 am local time, the intermittent, mild strombolian activity from the New SE crater began to increase, along with rising volcanic tremor.
The tremor is rapidly reached high values and its source shifted to a location southeast of the crater at a depth of 4-500 m, clear sign that a new gas-rich batch of magma had started its rise towards the conduit.
At around 3:15, the activity had reached the stage of lava fountaining from the crater and a lava flow started to descend from the eastern eruptive fissure towards the Valle del Bove.
Comparably bad weather conditions have prevented more detailed observations.
