• Rockfall activity MEDIUM

The volcanic activity is generally characterized by strombolian explosions with MEDIUM pressure (max 0.79 bar) and mainly located at the NE crater sector. Degassing (puffing/spattering), located at the NE crater sector, is characterized by VERY HIGH pressure values (100 mbar). The seismic tremor shows HIGH values. The volcano edifice does not show any significant deformation. The number of VLP events is MEDIUM (9.6 events/hour). The number of explosions detected by thermal camera is not available for technical reasons. MODIS/VIIRS images show LOW thermal anomalies (max 9.28 MW). SO2 flux was not evaluated. CO2 was not evaluated. The rockfall activity is MEDIUM (11 events detected with MEDIUM pseudo-volumes associated). The volcanic activity index is HIGH.
