The eruption tracker added: “The eruption was accompanied, as usual, by a sharp increase in tremor reflecting the sudden high discharge rate of magma being pushed to the surface by expanding gasses in a jet similar to opening a pressurized champagne bottle.”
Mount Etna is one of the most active volcanoes in the world and has erupted about 200 times since 1500 BC.
The volcano has been very active in recent years, and has been erupting for the last 500,000.
The year 2001 was particularly busy, with a spate of 16 eruptive events that began in July that year.
Activity was accompanied by earthquakes and the opening of at least five volcanic vents.
According to the US space agency NASA, which saw the eruptions from space, lava from the eruption flowed within three miles of the town of Nicolosi.
