Effusive activity continues without significant changes compared to yesterday. The lava flow on the Sciara is reaching about half way down the slope, and generates frequent small glowing rockfalls that reach the shore. The front of the flow is stable at around 450 m a.s.l.
The volcano observatory noted earlier today, that after careful analysis of satellite imagery and other data, it was found that the lava flow never reached the sea during the past days, only fragmented material that had descended from the flow and the crater area during the avalanche on Wednesday.
Activity at the summit craters continues as well: there is spattering activity mainly in the North and Center-South sectors and more intense explosive episodes are still being observed intermittently as well.
The amplitude of volcanic tremor is substantially stationary compared to the previous days, remaining at medium-low values. Frequency and amplitude of explosion events also do not show significant variations, and are actually at rather low levels.
No significant ground deformation is being measured.
This all points toward that the recent events were not caused by a true change in the state of the volcano, which could have been the arrival of new magma or other deep-seated changes, but rather related to superficial changes, such as that the crater rims over time had become destabilized and finally gave way after a certain threshold had been reached.
