Overview

• Mount Etna began its 13th eruptive phase on May 12, 2025, featuring 'stop-and-go' strombolian eruptions from the Southeast crater.
• Seismic tremor amplitude has steadily increased since midday on May 12, reaching high levels by 19:00 and continuing to rise.
• Forecast models predict any eruptive ash plume will disperse east-southeast, with no significant disruption to air travel reported so far.
• Monitoring networks have not detected significant ground deformation, and infrasound activity remains low despite ongoing eruptions.
• The Volcano Observatory Notice for Aviation (VONA) alert has been raised to orange, but Catania International Airport continues full operations.
