In the last 24h, the volcanic activity is characterised by Strombolian explosions and puffing, mainly located at the NE crater sector. Degassing activity shows HIGH values (puffing about 50 mbar) and the pressure of the explosions is MEDIUM (max acoustic pressure 0.9 bar). The thermal activity shows LOW number of explosions. The volcanic tremor shows oscillation from MEDIUM to HIGH values. The number of VLP events is MEDIUM (7.6 events/hour). MODIS and VIIRS satellite images show LOW thermal anomalies (3 MW). The SO2 flux, in the last 24h, was HIGH (182 t/d). The CO2 flux, based on the C/S ratio of 21.86 measured on 04/10/2024 at 21:20 UTC, is HIGH (2125 t/d). The rockfall activity is HIGH (30 events detected in the last 24h, with LOW to MEDIUM seismic pseudo-volumes involved). The volcanic activity index is HIGH.
