The volcanic activity is generally characterized by strombolian explosions and degassing (puffing/spattering) both located at the NE crater sector and by few explosions at SW crater. Explotions are characterized by MEDIUM values of pressure. A major event occurred at 14:20 UTC, yesterday. In the last 24h, the Stromboli volcano showed a HIGH degassing activity (puffing/spattering with values of about 58 mbar). The volcanic tremor shows HIGH values. The number of VLP events is MEDIUM (11.9 events/hour). SO2 flux shows MEDIUM value (last: 142 t/d ). The CO2 flux is HIGH (last: 1525 ton/day based on C/S 17.03 recorded on 03 November at 09:20 UTC). MODIS/VIIRS thermal data shows LOW thermal anomalies (max 1.07 MW). The rockfall activity is LOW. The volcanic activity index is HIGH.
