In the last 24h, the volcanic activity is characterised by Strombolian explosions and puffing located at the NE crater sector. Degassing and spattering activity, localized at NE crater, shows VERY HIGH values (150 mbar) and the pressure of the explosions is MEDIUM (max 1.3 bar). The volcanic tremor is HIGH. The number of VLP events is MEDIUM (10.3 events/hour). MODIS and VIIRS satellite images show LOW thermal anomalies in the last 24h. SO2 flux is MEDIUM while CO2 flux is not available. The rockfall activity is MEDIUM (19 events detected in the last 24h, with MEDIUM seismic pseudo-volumes involved). The volcanic activity index is HIGH.
