In the last 24h, the volcanic activity is characterised by Strombolian explosions and puffing, mainly located at the NE crater sector. Degassing and spattering activity, localized at NE crater, shows HIGH to VERY HIGH values (>100 mbar) and the pressure of the explosions is up to HIGH (> 1.5 bar). The volcanic tremor shows oscillations from HIGH to VERY HIGH values. The number of VLP events is MEDIUM (9.3 events/hour). MODIS and VIIRS satellite images show MEDIUM thermal anomalies. The SO2 and CO2 fluxes are MEDIUM. The rockfall activity is LOW (3 events detected in the last 24h, with LOW seismic pseudo-volumes involved). The volcanic activity index is HIGH.
