A new powerful paroxysmal eruptive episode (lava flow) occurred on Mount Etna, Italy, on July 14, 2021. The aviation color code was upgraded to red at 10:22 UTC. The estimated height of the volcanic cloud rose to over 9 km (29,500 ft) above sea level at 11:43 UTC, drifting northeast.
The volcanic tremor under the Southeast Crater began to intensify around 07:50 UTC, followed by a gradual transition of Strombolian activity to lava flowing, which lasted until 12:30 UTC.
INGV personnel on site reported large lava bombs dropped on the southern side of Bocca Nuova crater.
Abundant deposition of lapilli and ash (up to 1 cm / 0.4 inches or more) has been noted in the Rocca Campana. There are reports of volcanic ash and lapilli in Rifugio Citelli and Prese, and volcanic ash in Taormina.
After the paroxysm, weak strombolian activity persisted in the Southeast Crater. In addition, as of 12:30 UTC, the lava flow observed in the SE sector remained rechargeable.
Paroxysmal deformities peaked at 12:30 UTC.
