The INGV reported that strombolian activity has been picking up at the Etna’s Voragine crater around 10:00 PM local time last night. The elevated status is still continuing, even at the time of this update.
This followed a resumption of the activity yesterday afternoon as explosions became stronger and near-continuous.
An ash plume has been dissipating in the southern direction.
A volcanic tremor started to rise from average to high values from 06:00 PM local time yesterday. The seismic network located the tremor east of the Voragine crater at an altitude of approx. 2,800 meters.
Data from the GNSS hasn’t shown any significant ground deformation fluctuations.
According to the recent lava-fountaining episodes (paroxysms), gradual increase of strombolian activity culminated into violent lava-fountaining phases. Whether the current activity will lead to similar period, is not clear yet.
