The volcanic activity is generally characterized by few strombolian explosions with MEDIUM pressure (max 0.23 bar) and mainly located at the NE crater sector. Degassing (puffing/spattering), located at the NE crater sector, is characterized by MEDIUM pressure values (about 30 mbar). The seismic tremor is MEDIUM. The number of VLP events is MEDIUM (9.8 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 show LOW thermal anomalies. SO2 flux shows MEDIUM values (last: 149 t/d recorded on the 28/08/2024). CO2 was not evaluated. The rockfall activity is MEDIUM (13 events detected with LOW pseudo-volumes associated). The volcanic activity index is HIGH.
