The number of VLP seismic events (standard values 5-12) is medium, 8.6 events/hour.

The amplitude of seismic tremor is medium.

The infrasonic activity is medium. The acoustic pressure of explosions is low, 0.5 bar (standard values <1 bar). The amplitude of puffing is low, ~39 mbar.

Tiltmeters analysis does not show any significant deformation of the volcano edifice

Thermal activity of explosive events is not available. The number of thermal transients in the NE sector of the crater(standard = 100) is not available. The amplitude of thermal transients is not available. Exit velocity of pyroclasts, estimated through thermal camera analysis, is not available.

MODIS thermal anomalies are low: 0.1 MW (01:30 UTC yesterday).

Rockfall activity is medium. The number of rockfalls is 3 per day.

SO2 flux in the NE sector of the crater terrace is low, 48 t/d

CO2 flux based on the C/S is not available

Indice di Attività Vulcanica: medium

  • Seismic (VLP) rate MEDIUM
  • Seismic tremor MEDIUM
  • Puffing LOW
  • Acustic pression of explosions LOW
  • Thermal activity NOT AVAILABLE
  • SO2 flux LOW
  • CO2 flux not available
  • Rockfall activity MEDIUM

The volcanic activity is characterized by Strombolian explosions located at the NE crater sector and degassing (puffing/spattering) located at the NE crater sectors. In the last 24h, degassing activity (puffing/spattering) was MEDIUM, with explosive transients having MEDIUM acoustic pressure. The volcanic tremor is MEDIUM. The number of VLP events has MEDIUM values (8.6 events/hour). In the last 24 hours LOW thermal anomalies are detected by MODIS/VIIRS data. SO2 flux shows LOW values (last: 48 t/d), while for CO2 flux not new data are available. The rockfall activity has recorded by LOW number of event which are charcterized by low amplitude. The volcanic activity index is MEDIUM.
