The number of VLP seismic events (standard values 5-12) is medium, 8.1 events/hour.

The amplitude of seismic tremor is high.

The infrasonic activity is medium. The acoustic pressure of explosions is low, 0.8 bar (standard values <1 bar). The amplitude of puffing is medium, ~60 mbar.

Tiltmeters analysis does not show any significant deformation of the volcano edifice

The volcanic activity is generally characterized by Strombolian explosions located at the NE and SW crater sectors and a degassing (puffing/spattering) mainly located at SW crater sectors. In the last 24h, the volcano showed a HIGH degassing activity (puffing/spattering with values of about 60 mbar) at SW sector. The explosive activity shows MEDIUM values (up to 0.8 bar). The volcanic tremor shows HIGH values. The number of VLP events shows MEDIUM values (8.1 events/hour). MODIS/VIIRS thermal data shows LOW thermal anomalies (2 MW). SO2 and CO2 fluxes show LOW values (26 and 231 t/d, respectively). The rockfall activity is LOW (1 event) with associated LOW pseudo-volumes. The volcanic activity index is MEDIUM. (NB the recorded data are conditioned by the adverse weather conditions: strong wind)
