Overview

• The northern flank of Etna’s Southeast crater collapsed on June 2, generating a pyroclastic flow and an eruptive cloud that climbed several kilometers above the summit.
• Lava fountaining broke out immediately at the Southeast crater as volcanic tremors spiked to very high values, according to the INGV Osservatorio Etneo.
• A small lava overflow from the crater’s southern rim has sent a modest flow toward Valle del Bove without breaching the rim of Valle del Leone.
• The INGV observatory has issued a red alert for aviation with an orange forecast for ash dispersion over surrounding airspace.
• Local reports confirm a light fall of fine ash in Piano Vetore as the ongoing eruptive phase continues to develop.
