The volcanic activity is characterized by Strombolian explosions located at the NE and SW crater sectors and degassing (puffing/spattering) located at the NE crater sectors. In the last 24h, degassing activity (puffing/spattering) was HIGH (60 mbar), with explosive transients having MEDIUM acoustic pressure (max 0.51 bar). The volcanic tremor is MEDIUM. The number of VLP events has MEDIUM values (7.9 events/hour). MODIS/VIIRS thermal data don't show thermal anomalies. SO2 flux shows LOW values (last: 29 t/d). No new data of CO2 flux are available. The rockfall activity is LOW (no events during the last 24h). The volcanic activity index is MEDIUM.
