The number of VLP seismic events (standard values 5-12) is medium, 9.6 events/hour.

The amplitude of seismic tremor is medium.

The infrasonic activity is not available. The acoustic pressure of explosions is not available. The amplitude of puffing is not available

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.

The volcanic activity is characterized by strombolian explosions. In the last 24h acoustic pressures were not evaluated due to adverse weather conditions. The number of VLP events shows MEDIUM values (9.6 events/hour). Thermal activity was not evaluated due to adverse weather conditions. The volcanic tremor is MEDIUM. MODIS/VIIRS images showed LOW thermal anomalies. SO2 flux shows MEDIUM values (71 t/d). CO2 flux was not evaluated. Rockfall activity is LOW with 4 events detected in the last 24h. The volcanic activity index is MEDIUM.
