The day of 18 March was marked in Etna by a few striking episodes:
The explosive activity ceased at around 11 am at the central vent of the southeast cone, while the effusion of lava continued to feed the flow towards the Valle del Bove. The trajectory of the tremor stabilized from this hour.

Twice during the afternoon, between 15:40 and 16:15 local, and between 18:40 and 19:10, the interaction between lava and snow caused the formation of pyroclastic avalanches / lahars on the steep slopes of the Valle Del Bove. The phenomenon was accompanied by the development of a cloud of ash and water vapor.
Please note: Catania airport was closed several hours
