The number of VLP seismic events (standard values 5-12) is medium, 10.1 events/hour.
The amplitude of seismic tremor is medium.
The infrasonic activity is medium. The acoustic pressure of explosions is low, 0.6 bar (standard values <1 bar). The amplitude of puffing is medium, ~80 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 are low: 1.27 MW (00:30 UTC yesterday).
Rockfall activity is low. The number of rockfalls is 1 per day.
SO2 flux in the NE sector of the crater terrace is low, 56 t/d
CO2 flux based on the C/S is not available

In the last 24h, the volcanic tremor showed MEDIUM values. The number of VLP events has MEDIUM values (10.1 events/hour). Infrasonic data show strombolian explosions of MEDIUM amplitudes (max. 0.6 bar) and a degassing activity of HIGH amplitude (max 80 mbar). MODIS/VIIRS thermal data shows LOW thermal anomaly. SO2 flux shows LOW values and CO2 fluxes are not available. The rockfall activity is LOW (1 event detected in the last 24 hours with LOW associated pseudo-volumes). The volcanic activity index is MEDIUM.
