The volcanic activity is generally characterized by strombolian explosions located at the NE crater sector and puffing localized at the C and SW crater sector. In the last 24h, the Stromboli volcano showed a MEDIUM degassing activity and LOW acustic pressure. The number of explosions (thermal transients) are LOW, with a MEDIUM thermal amplitude and MEDIUM exit velocity of pyroclasts. The volcanic tremor shows MEDIUM values. The number of VLP events is MEDIUM. MODIS/VIIRS images showed LOW thermal anomalies. The SO2 flux is LOW. The volcanic activity index is MEDIUM.
