The number of VLP seismic events (standard values 5-12) is medium, 8.4 events/hour.

The amplitude of seismic tremor is very high.

The infrasonic activity is very high. The acoustic pressure of explosions is high, 2 bar (standard values <1 bar). The amplitude of puffing is high, ~100 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 low, 26. The amplitude of thermal transients is not available. Exit velocity of pyroclasts, estimated through thermal camera analysis, is low, 15 m/s.

MODIS thermal anomalies are medium: 25 MW (12:08 UTC yesterday).

Rockfall activity is low. The number of rockfalls is 3 per day.

SO₂ flux in the NE sector of the crater terrace is high, 230 t/d

CO₂ flux based on the C/S of 20.24 mesured at 05:25 UTC on 2024/10/10 is very high, 3788 t/d

In the last 24h, the volcanic activity is characterised by Strombolian explosions and puffing, mainly located at the NE crater sector. Degassing and spattering activity, localized at NE crater, shows HIGH to VERY HIGH values (>100 mbar) and the pressure of the explosions is up to VERY HIGH (> 2 bar). The volcanic tremor shows oscillations from HIGH to VERY HIGH values. The number of VLP events is MEDIUM (8.4 events/hour). MODIS and VIIRS satellite images show LOW thermal anomalies (9 MW). The SO2 flux, in the last 24h, has been HIGH (230 t/d). The CO2 flux, based on the C/S ratio of 20.24 measured on 10/10/2024 at 05:25 UTC, is VERY HIGH (3788 t/d). The rockfall activity is LOW (3 events detected in the last 24h, with LOW to HIGH seismic pseudo-volumes involved). The volcanic activity index is HIGH.
