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

The amplitude of seismic tremor is medium.

The infrasonic activity is medium. The acoustic pressure of explosions is low, 0.15 bar (standard values <1 bar). The amplitude of puffing is low, ~30 mbar.

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

Thermal activity of explosive events is low. The number of thermal transients in the NE sector of the crater (standard = 100) is low, 39. The amplitude of thermal transients is low, 1 ºF. Exit velocity of pyroclasts, estimated through thermal camera analysis, is low, 17 m/s.

MODIS thermal anomalies are low: 4 MW (12:18 UTC yesterday).

The volcanic activity is characterized by strombolian explosions and degassing activity (puffing) mainly located at the SW and NE crater sectors. The number of VLP events shows HIGH values (12.0 events/hour). Infrasonic activity is characterized by explosions of MEDIUM pressure and puffing of MEDIUM amplitude. Seismic tremor values are MEDIUM. Thermal activity at the craters is LOW. MODIS/VIIRS images show LOW thermal anomalies. SO2 flux shows MEDIUM values. CO2 flux, based on a C/S ratio of 13.74, show MEDIUM values (616 t/d), measured on 08/02 at 00:20 UTC. Rockfall activity is LOW with 3 events detected in the last 24h. The volcanic activity index is MEDIUM. NB: Thermal and Infrasonic values could be underestimated due cloud cover.
