The volcanic activity is characterized by Strombolian explosions located at NE and C/SW crater sector and degassing (puffing/spattering) located at prevalently at C/SW crater sectors. In the last 24h, degassing activity (puffing/spattering) showed MEDIUM values (45 mbar). The explosive activity is MEDIUM (max acoustic pressure 1.3 bar). The volcanic tremor shows MEDIUM values, with associated a MEDIUM number of VLP events (12.9 events/hour). MODIS/VIIRS thermal data shows LOW (1 MW) thermal anomalies. SO2 flux shows MEDIUM values (last: 71 t/d ), CO2 flux is MEDIUM. The number of rockfall activity is MEDIUM (10 events detected in the last 24 h), with associated LOW pseudo-volumes). The volcanic activity index is MEDIUM.
