The number of VLP seismic events (standard values 5-12) is medium, 9.2 events/hour.

The amplitude of seismic tremor is 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, ~140 mbar.

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

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 (up to 1 bar) and VERY HIGH degassing activity (puffing/spattering with pressure values of about 140 mbar). The volcanic tremor shows HIGH values. The noumber of VLP events is MEDIUM (9.2 events/hour). SO2 flux from NE sector is MEDIUM (93 t/d). CO2 flux measures is MEDIUM (697 t/d) retrieved by C/S ratio of 8.09 measured at 07:20UTC of today. MODIS and VIIRS satellite images doesn't show thermal anomalies. No events of rockfall have been detected in the last 24 hours. The Volcanic Activity Index is HIGH.
