INGV, Italy’s national geophysics and volcanology institute, said a 2am (1am GMT) explosion was the 10th since February 16. The volcano’s plume showered eight Sicilian villages with ash, covering parked cars and roads.
No injuries or instances of serious damage have been reported following the latest blast from Etna.
Scientists observing the volcano shared the column of ash and stone surged as high as 10,000 meters (33,000 feet) on Sunday.
INGV added winds swept the ash clouds eastwards, covering homes.
A small and slow flow of lava also travelled down the southeast crater towards an uninhabited side of the mountain.

It follows scientists warning Etna could trigger a tsunami “in the entire Mediterranean” in the future, after previous warnings it was “sliding” towards the sea.
More than 100 GPS station readings taken in 2018 showed the volcano appeared to be slowly and steadily sliding into the Mediterranean Sea.
Lead researcher Dr John Murray added in 2018: “Previous studies of long-extinct volcanoes found those sliding downslope in a similar way have resulted in catastrophic landslides later in their history.
“Constant movement could contribute to a major landslide along Etna’s coast, causing devastating tsunamis to the surrounding areas.”
