The volcanic activity is characterized by strombolian explosions and degassing activity (puffing). The number of VLP events shows MEDIUM values (10.4 events/hour). Seismic tremor values are MEDIUM. MODIS/VIIRS images showed NO thermal anomalies. SO2 and CO2 flux values are not available. Rockfall activity is LOW with 1 event detected in the last 24h with LOW seismic enercy associated. The volcanic activity index is MEDIUM.
