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 60 mbar) and the pressure of the explosions shows MEDIUM (up to 1.4 bar). The volcanic tremor shows oscillations with an overall HIGH values. The number of VLP events is MEDIUM (9.9 events/hour). MODIS and VIIRS satellite images show LOW thermal anomalies (9 MW). The SO2 flux, in the last 24h, has been MEDIUM (115 t/d) with early measures of today that record an increase to HIGH (192 t/d). The CO2 flux, based on the C/S ratio of 10.07 measured on 09/10/2024 at 07:20 UTC, is HIGH (1983 t/d). The rockfall activity is HIGH (13 events detected in the last 24h, with LOW to HIGH seismic pseudo-volumes involved). The volcanic activity index is HIGH.
