The volcanic activity is generally characterized by strombolian explosions with MEDIUM pressure (max 0.6 bar), rich in scoria, located at the NE crater sector. Sporadic sustained explosions with only ash occur at the SW crater sector. Degassing (puffing/spattering), located at the NE crater sector, is characterized by HIGH pressure values (about 60 mbar). The seismic tremor fluctuates between MEDIUM and HIGH levels . The number of VLP events showed MEDIUM values (9.5 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 HIGH exit velocity of pyroclasts. MODIS/VIIRS thermal data shows no thermal anomaly due to bad weather conditions. SO2 flux shows VERY HIGH values (last: 264 t/d recorded on the 20/08/2024). CO2 flux shows VERY HIGH values (last: 3016 t/d based on C/S value of 12.04 recorded on the 20/08/2024). The rockfall activity is MEDIUM (7 events detected with LOW pseudo-volumes associated). The volcanic activity index is HIGH.
