The number of VLP seismic events (standard values 5-12) is medium, 11.9 events/hour.

The amplitude of seismic tremor is high.

The infrasonic activity is high. The acoustic pressure of explosions is low, 0.7 bar (standard values <1 bar). The amplitude of puffing is medium, ~58.6 mbar.

Tiltmeters analysis show a deformation of the volcanic edifice of about 0.4 microradians not associated with an explosive event.

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. 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: 89 t/d ). The CO2 flux is HIGH (last: 2199 ton/day based on C/S 13.19 recorded on 02 November at 09:20 UTC). MODIS/VIIRS thermal data shows no thermal anomalies. The rockfall activity is LOW. The volcanic activity index is HIGH.
