The number of VLP seismic events (standard values 5-12) is medium, 10.5 events/hour.

The amplitude of seismic tremor is very high.

The infrasonic activity is high. The acoustic pressure of explosions is medium, 1 bar (standard values <1 bar). The amplitude of puffing is high, ~120 mbar.

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

Thermal activity of explosive events is not available. 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: no thermal anomalies.

Rockfall activity is high. The number of rockfalls is 17 per day.

The volcanic activity is characterized by Strombolian explosions and degassing (puffing/spattering) occurring at the NE crater sector. Explosions are associated with MEDIUM pressure values (maximum 1.3 bar), with VERY HIGH degassing activity (puffing/spattering with pressure values of about 120 mbar). The volcanic tremor is stable with oscillations at VERY HIGH values. The noumber of VLP events is MEDIUM (10.5 events/hour). SO2 flux from NE sector is LOW (65 t/d), with early measures of today showing an increase to MEDIUM levels. CO2 flux measures is VERY HIGH (4821 t/d) retrieved by C/S ratio of 23.81 measured at 01:20UTC of today. MODIS and VIIRS satellite images doesn't show thermal anomalies. Rockfall activity is HIGH, with 17 events detected in the past 24 hours. The Volcanic Activity Index is HIGH.
