The volcanic activity is generally characterized by strombolian explosions and degassing (puffing/spattering). Due to Storm Henry, many volcano monitoring parameters are currently unavailable. In the last 24h, the volcanic tremor shows MEDIUM values. MODIS/VIIRS thermal data shows no thermal anomalies. SO2 flux shows no new data LOW values (last: 47 t/d recorded on the 19/01/2026), CO2 flux shows no new data (last: 337 t/d based on C/S value of 6.1 recorded on the 15/01/2026). The volcanic activity index is MEDIUM. (NB Recorded data is affected by severe weather conditions: Strong wind and stormy weather)
