Mount Etna eruption of December 24, 2018
Mt Etna greets Christmas with a new and spectacular eruption. On the morning of the 24 of December new vents opened at the base of the south-east crater and into the Valle del Bove, the wide Caldera covering the eastern flank of the volcano. Following the explosive activity a large plume of volcanic ash rose high in the sky from Etna, causing the temporary closure of the Catania airport. Later on the afternoon a few sectors has been reopened but with many restrictions.
The phenomenon has been characterized by the intrusion of a magmatic dike in the high eastern flank of the volcano, which has generated an intense earthquake swarm and showy ground deformation. An activity, says the Institute of geophysics and volcanology of Catania, followed by a gradual increase in degassing from the summit crater area that has in fact affected three of the five active craters of the Volcano.
Initially, there were sporadic ash emissions from both the Bocca Nuova and the Northeast Crater, culminating at around 12 am in a thick and incessant high plume of ash. Five minutes later, an intense Strombolian activity began and the lava start flowing down into the Valle del Bove depression.
