Between June 22 and 25, 2026, Mount Etna’s( the most active volcano in Europe) summit’s craters spewed sustained lava fountains and an ash column that reached 8,000 meters above sea level.

The Italy National Institute of Geophysics and Volcanology (INGV) had reported that lava was floating on Mount Etna’s eastern side. This latest eruption occurred on Monday night, when experts say that molten rock gushed from an eruptive vent at an altitude of around 3,000 meters. Most lava was contained within the Valle del Bove, a deep valley on the volcano’s flank, leaving nearby residential areas largely unthreatened. Fine volcanic ash drifted as far as the coastal towns of Taormina and Siracusa, 50+ km from the summit, but local authorities only advised residents to avoid outdoor exercise for 48 hours—no long-term air quality alerts were issued. Catania Airport in eastern Sicily temporarily closed for three hours to avoid ash ingestion risk, with zero reported injuries or fatalities.

Mount Etna’s activity is dominated by effusive lave flows rather than violent explosive eruptions.

The volcano stands around 3,400 metres tall and has a base that measures just under 100 miles. Mount Etna is known as the most active volcano in Europe. Etna’s near-constant activity stems from its location on the boundary of the African and Eurasian tectonic plates. Ongoing subduction feeds a steady supply of magma, making it one of he most frequently erupting volcanoes on Earth.

This specific eruption gave volcanologists a rare clear widow to study Etna’s magma mixing pattern. Samples collected from the flow confirmed a new, previously-undocumented blend of deep and shallow magma layers, which will update existing eruption prediction models for the volcano.

Activity has since dropped back to baseline seismic levels, with no alerts for imminent large-scale eruption.
