In the last 24h, the volcanic activity is characterized by Strombolian explosions with HIGH acoustic pressures (max 1 bar), located at the NE and SW crater sectors. The degassing activity (puffing/spattering), located at the SW sector, shows MEDIUM values (average of 12.9 mbar). The volcanic tremor has MEDIUM values. The number of VLP events is HIGH (18.7 events/hour). MODIS and VIIRS satellite images show LOW thermal anomalies (max 2 MW). SO2 flux shows LOW values (11 t/d). CO2 flux, evaluated using the C/S ratio of 9.52, measured on 07/06/2026 at 23:20 UTC, is LOW (107 t/d). The volcanic activity index is MEDIUM.
