In the last 24h, the volcanic activity is characterized by Strombolian explosions with HIGH acoustic pressures (max 1.45 bar), located at the NE crater sector. The degassing activity (puffing/spattering), located at the SW sector, shows MEDIUM values (average of 40 mbar). The volcanic tremor has MEDIUM values. The number of VLP events is HIGH (13.1 events/hour). MODIS and VIIRS satellite images show LOW thermal anomalies (max 7.28 MW). SO2 flux shows MEDIUM values (109 t/d). No new data of CO2 flux are available. The number of rockfalls is LOW (no events detected in the last 24h). The volcanic activity index is MEDIUM.
