The volcanic activity is characterized by Strombolian explosions located at the NE crater sector and degassing (puffing/spattering) located prevalently at SW crater sector. In the last 24h, the volcano showed a MEDIUM degassing activity (puffing/spattering with values of about 30 mbar). The explosive activity is MEDIUM (max acoustic pressure 0.9 bar). The volcanic tremor shows HIGH values, partially due to strong wind. The number of VLP events shows MEDIUM values (9.8 events/hour). MODIS/VIIRS thermal data shows MEDIUM thermal anomalies (21 MW). SO2 flux shows MEDIUM values (last: 73 t/d ), CO2 flux is MEDIUM (571 t/d). The rockfall activity is LOW (n.1 event detected with LOW pseudo-volumes associated). The volcanic activity index is MEDIUM.
