The volcanic activity is characterized by strombolian explosions and degassing (puffing/spattering) located at the SW crater sector. In the last 24h, the volcano showed a MEDIUM degassing activity (puffing/spattering with values of about 40 mbar). The explosive activity is MEDIUM (max acoustic pressure 0.3 bar). The volcanic tremor shows MEDIUM values. The number of VLP events shows MEDIUM values (10.3 events/hour). MODIS/VIIRS thermal data shows no thermal anomaly. SO2 flux is LOW (last: 27 t/d), CO2 flux is not available. The rockfall activity is LOW (no event detected in the last 24 hours). The volcanic activity index is MEDIUM.
