The number of VLP seismic events (standard values 5-12) is medium, 10.7 events/hour.
The amplitude of seismic tremor is medium.
The infrasonic activity is high. The acoustic pressure of explosions is low, 0.63 bar (standard values <1 bar). The amplitude of puffing is medium, ~60 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 medium. The number of rockfalls is 5 per day.
SO2 flux in the NE sector of the crater terrace is low, 31 t/d
CO2 flux based on the C/S is not available

In the last 24h, the volcanic activity is characterized by Strombolian explosions with MEDIUM acoustic pressures (max 0.63 bar), located at the NE and SW crater sectors. The degassing activity (puffing/spattering), mainly located at the SW sector, shows HIGH values (average of 60 mbar). The volcanic tremor has MEDIUM values. The number of VLP events is MEDIUM (10.7 events/hour). MODIS and VIIRS satellite images don't show thermal anomalies. SO2 flux shows LOW values (31 t/d). No new data of CO2 flux are available. The number of rockfalls is MEDIUM (5 events detected in the last 24h, with MEDIUM pseudo-volumes involved). The volcanic activity index is MEDIUM.
