The number of VLP seismic events (standard values 5-12) is medium, 8.5 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

Thermal activity of explosive events is low. The number of thermal transients in the NE sector of the crater(standard = 100) is not available. The amplitude of thermal transients is not available. Exit velocity of pyroclasts, estimated through thermal camera analysis, is not available.

MODIS thermal anomalies are low: 3 MW (00:54 UTC yesterday).

Rockfall activity: no rockfalls detected.

SO₂ flux in the NE sector of the crater terrace is low, 46 t/d

CO₂ flux based on the C/S of 9.59 mesured at 03:20 UTC on 2025/10/18 is medium, 452 t/d

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 1 bar). The volcanic tremor shows HIGH values,with hourly-long phases reaching VERY HIGH values. The number of VLP events shows MEDIUM values (8.5 events/hour). MODIS/VIIRS images show LOW thermal anomalies (3 MW). SO2 flux show LOW values (46 t/d). CO2 flux retrieved by C/S ratio of 9.59 measured at 03:20 of yesterday, shows MEDIUM values. The rockfall activity is absent, no event detected. The volcanic activity index is MEDIUM. (NB the recorded data are conditioned by the adverse weather conditions: strong wind)
