The volcanic activity is characterized by Strombolian explosions located at NE and SW crater sector and degassing (puffing/spattering) located prevalently at C/SW crater sectors. In the last 24h, degassing activity (puffing/spattering) showed MEDIUM values (~40 mbar). The explosive activity is MEDIUM (max acoustic pressure 0.28 bar). The volcanic tremor shows MEDIUM values, with associated a MEDIUM number of VLP events (9.75 events/hour). MODIS/VIIRS thermal data shows LOW thermal anomalies. SO2 flux shows LOW values (last: 38 t/d ), CO2 flux was not evaluated. The number of rockfall is LOW (6 events detected in the last 24 h having LOW seismic energies). The volcanic activity index is MEDIUM.
