The volcanic activity is characterized by lava flows emitted from vents located at about 500 m a.s.l. In the last 24h, degassing activity and the pressure of the explosions are absent. The volcanic tremor shows MEDIUM values. The number of VLP events shows HIGH values (12.1 events/hour). Thermal activity is absent. MODIS/VIIRS images showed HIGH thermal anomalies (670 MW). CO2 flux, based on the C/S ratio of 2.16 measured on 09/07/2024 at 19:20 UTC, is MEDIUM (901 t/d). The rockfall activity is HIGH (VERY HIGH number of events characterized by LOW and MEDIUM pseudo-volume associated). The volcanic activity index is VERY HIGH.
