Etna is Europe’s largest active volcano and is the largest of Italy’s three active volcanoes.
Two powerful lava arms emerged from the volcano, the National Institute of Geophysics and Volcanology (INGV) of Catania reported.
The first “arm” sprung from the south-east crater and headed towards the Valle del Bove, which is uninhabited, while some ash blew over some of the nearby towns.
There there were no reports of damage or injuries.
The second lava overflow was detected from the north side of the same crater.
The volcano continued to be active on Tuesday.
