The volcanic activity is generally characterized by Strombolian explosions and degassing (puffing/spattering) mainly located at SW and NE crater sectors. In the last 24h, the volcano showed a MEDIUM degassing activity (puffing/spattering with values of about 36 mbar) at SW sector. The explosive activity features explosions with MEDIUM values of acoustic pressure (<0.21 bar) mainly at the NE sector. The volcanic tremor shows MEDIUM values. The number of VLP events shows HIGH values (13.9 events/hour). MODIS/VIIRS thermal data show LOW thermal anomalies. The SO2 flux shows LOW values (45 t/d), while CO2 flux was not evaluated. The rockfall activity is LOW (no events detected in the last 24h). The volcanic activity index is MEDIUM.
