Strong explosive activity at Etna opens new vent feeding lava flow toward Valle del Bove, Italy

"Etna’s eruptive activity intensified rapidly between December 24 and 27, 2025, culminating in short-lived lava fountains about 200 m (650 feet) high and a new lava flow from the upper Voragine crater toward the Valle del Bove. INGV Etna Observatory (OE) raised the Aviation Color Code to Red as tremor and infrasound amplitudes reached very high levels." W
