The volcanic activity is generally characterized by strombolian explosions with MEDIUM pressure (max 1.36 bar) and located at the NE crater sector. Degassing (puffing/spattering), located at the NE crater sector, is characterized by VERY HIGH pressure values (about 101 mbar). The seismic tremor is HIGH showing sporadic fluctuations towards VERY HIGH values. The number of VLP events is MEDIUM (9.2 events/hour). The analysis does not show any significant deformation of the volcanic edifice. The number of explosions (thermal transients) is HIGH, with a HIGH thermal amplitude and LOW exit velocity of pyroclasts. MODIS/VIIRS thermal data shows LOW thermal anomaly. SO2 flux shows MEDIUM values (last: 102 t/d recorded on the 24/08/2024). CO2 flux and C/S ratio were not evaluated. The rockfall activity is LOW (3 events detected with LOW pseudo-volumes associated). The volcanic activity index is HIGH.
