The number of VLP seismic events (standard values 5-12) is medium, 10.1 events/hour.

The amplitude of seismic tremor is high.

The infrasonic activity is high. The acoustic pressure of explosions is medium, 1.5 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 high. The number of thermal transients in the NE sector of the crater (standard = 100) is high, 699. The amplitude of thermal transients is high, 36 ºF. Exit velocity of pyroclasts, estimated through thermal camera analysis, is high, 40 m/s.

The volcanic activity is generally characterized by strombolian explosions with HIGH pressure (max 2.51 bar), rich in scoria, located at the NE crater sector. Sustained explosions with only ash occur at the SW crater sector. Degassing (puffing/spattering), located at the NE crater sector, is characterized by HIGH to VERY HIGH pressure values (about 100 mbar). This activity is correlated with seismic tremor characterized from HIGH to VERY HIGH values. The number of VLP events showed MEDIUM values (10 events/hour). The number of explosions (thermal transients) are HIGH, with a HIGH thermal amplitude and HIGH exit velocity of pyroclasts. MODIS/VIIRS thermal data shows LOW values (max 9 MW), consistent with the observed activity. SO2 flux shows VERY HIGH values (last: 268 t/d recorded on the 17/08/2024). CO2 flux shows VERY HIGH values (last: 3306 t/d based on C/S value of 12.13 recorded on the 17/08/2024). The rockfall activity is HIGH (19 events detected with LOW pseudo-volumes associated). The volcanic activity index is HIGH.
