The volcanic activity is characterized by strombolian explosions and degassing activity (puffing). Data of acoustic pressure of explosions and degassing activity of the ast 24 hours are not available. The number of VLP events shows MEDIUM values (11.0 events/hour). Thermal activity is characterized by a LOW number of transients having LOW thermal amplitude and MEDIUM exit velocity of pyroclasts. MODIS/VIIRS images showed LOW thermal anomalies (max 0.27 MW at 01:12 of 05/01/2024). SO2 flux shows LOW values (56 t/d). CO2 flux, estimated from a C/S ratio of 8.07, is HIGH (1415 t/d). Rockfall activity is MEDIUM with 7 events detected in the last 24h generating mainly LOW seismic energies. The volcanic activity index is MEDIUM. N.B.: thermal data could be underestimated due to several hours of missing data
