The volcanic activity is characterized by Strombolian explosions and puffing located at NE and C craters sector. In the last 24h, degassing activity was HIGH (puffing 80 mbar), associated to spattering activity located at NE crater. The pressure of the explosions is MEDIUM (max acoustic pressure 0.2 bar). The number of thermal transients by thermal cameras is LOW, with LOW amplitude and LOW exit velocity. The volcanic tremor showed HIGH values. The number of VLP events shows HIGH values (18.4 events/hour). MODIS/VIIRS images showed LOW thermal anomalies. SO2 flux is LOW and CO2 flux is MEDIUM. The rockfall activity is LOW. The volcanic activity index is HIGH.
