In the last 24h, the volcanic activity is characterized by Strombolian explosions with HIGH acoustic pressures (max 1.06 bar), located at the NE and SW crater sectors. The degassing activity (puffing/spattering), mainly located at the SW sector, shows HIGH values (average of 50 mbar). The volcanic tremor has MEDIUM values. The number of VLP events is HIGH (12.1 events/hour). MODIS and VIIRS satellite images show MEDIUM thermal anomalies (max 11.24 MW). SO2 flux shows LOW values (47 t/d). No new data of CO2 flux are available. The number of rockfalls is MEDIUM (5 events detected in the last 24h, with LOW pseudo-volumes involved). The volcanic activity index is MEDIUM.
