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 VERY HIGH values (>150 mbar) and the pressure of the explosions is VERY HIGH (>2.0 bar). The volcanic tremor is HIGH to VERY HIGH. The number of VLP events is MEDIUM (10.3 events/hour). MODIS and VIIRS satellite images show LOW thermal anomalies. The SO2 and CO2 fluxes are LOW. The rockfall activity is MEDIUM (7 events detected in the last 24h, with LOW seismic pseudo-volumes involved). The volcanic activity index is HIGH.
