Overview

• The new effusive vent opened on Bocca Nuova’s southern flank at around 3,000 meters altitude on August 10.
• The lava flow is advancing toward the south from the new vent.
• Seismic tremor remains stable at approximately 2,800 meters between the Voragine and Northeast craters, with no significant infrasonic signals detected.
• An orange VONA flight alert is in force, but Catania–Fontanarossa Airport continues normal operations despite the lava advance.
• This effusive event succeeds a series of explosive and strombolian phases earlier in the year, highlighting Etna’s alternating eruptive patterns and the need for adaptable hazard response.
