Earth Changes
At 3,3057 metres, it's Europe's tallest volcano and has been constantly active in the past ten years.
But no one has been injured and no one is in danger.
Volcanologists have described the activity on Etna in recent days as a succession of Strombolian eruptions - which are moderately explosive but short eruptions named after the volcano on the nearby island of Stromboli.

Experts are warning that supermarkets could be forced to turn to imports from as far afield as Egypt to fill potential gaps on shelves, pushing up the environmental impact of the festive meal.
Comment: The Guardian journalists are worried about the (relatively inconsequential) Co2 emissions - as world leaders fly to the UAE in their private jets for the COP28 climate summit - meanwhile, as inflation continues to push up prices, tens of millions of people in the West worry about how they're going to be able to afford the Christmas celebrations.
Fred Searle, the magazine editor of the Fresh Produce Journal, said potato planting had reduced significantly and the sector was "looking at the lowest UK crop on record this season", with an estimate that about "4.1m tonnes of potatoes would be harvested, 2m less than five or six years ago".
The solar storm, or coronal mass ejection (CME), could interfere with the Earth's magnetic field and is likely to impact various forms of communications as well as sparking vibrant auroras, space weather physicist Tamitha Skov said.
"The storm is predicted to hit Earth by midday December 1... If the magnetic field is oriented correctly, expect aurora to reach deep into mid-latitudes. Amateur radio and GPS reception issues are likely, especially on Earth's nightside," Dr Skov posted on X.
The US National Oceanic and Atmospheric Administration (NOAA) and other forecasters had already predicted that three solar storms were heading towards the Earth with some of them likely to merge to produce stronger magnetic field disruptions.

Dozens of passengers in Ukraine have had to be rescued from vehicles stuck in heavy snow
They say 48 people, including children, have been evacuated from trapped vehicles in the worst-affected Odesa region in the south-west.
At least six people have suffered from hypothermia. Traffic is currently blocked on 14 motorways.
Comment: Update November 28
CNN reports:
At least 10 people have died and thousands remain cut off from the power grid in Ukraine, in three days of stormy weather that has blanketed parts of the country in heavy snow, a senior official said Tuesday.
More than 400 settlements across 11 regions were without electricity, and more than 1,500 responders were trying to reach thousands of people in need of rescue, Interior Minister Ihor Klymenko wrote on Telegram, as fresh bouts of snow are expected to continue this week.
Another 23 were injured, including two children, Klymenko said Tuesday, adding the deaths were in Odesa, Kharkiv, Mykolaiv and Kyiv regions.
Videos showed Ukrainian police battling fierce winds as they pushed and towed cars back onto icy highways after they had slid off-road into ditches.
Spotting a deep-sea oarfish species is a signal for an impending quake, according to Japanese folklore.
The elongated fish was spotted on the shores of Los Coquitos beach in Pepillo Salcedo, Dominican Republic on Monday.
The oarfish died shortly after.
The sea serpent was eerily located near the Septentrional-Oriente strike-slip Fault Zone, responsible for the 1842 Cap-Haïtien earthquake and tsunami in neighbouring Haiti, which killed approximately 5,300.
As expected, more than 40 inches of snow fell over the past two days over parts of the Great Lakes and interior Northeast in the first significant lake-effect snow event of the season.
The heaviest snowfall was recorded at Constableville, New York, where 42.7 inches landed.
All lake-effect snow warnings expired at 7 a.m. Wednesday. By the afternoon, the snow was winding down across the Great Lakes, with a few flurries or light snow showers trickling across lakes into northwest Pennsylvania and western New York. Heavy snowfall is not expected through the rest of Wednesday, but 1 or 2 inches of snow will still be possible.
But the nature guide's latest interaction on Tasmania's east coast has left him devastated.
He along with two of his colleagues had travelled by boat to Bryans Beach, not far from the popular tourist destination of Wineglass Bay.
It was there they came across more than two dozen pilot whales lying in the shallows on Wednesday morning.
All of them were dead.
"It was pretty heart-wrenching," Mr Theobald said.

The water level in Boon Lay Avenue almost reached the height of the seats of a bus stop, with vehicles travelling slowly along that road.
National water agency PUB said on Facebook the same evening that a flash flood had occurred in Boon Lay Way at 3.42pm. It subsided within 20 minutes.
In a separate alert on Telegram earlier in the afternoon, it said the flash flood affected two of the three lanes there.
PUB said on Facebook that its quick response teams were on site to help the public. It added that it had issued flood risk alerts for six locations.
Videos posted on Facebook show the water level in Boon Lay Avenue near River Valley High School almost reaching the height of seats at a bus stop, with vehicles travelling slowly along that road.
The past week has seen more big accumulations of typically 50-100cm (20-40″) on high slopes, 10-20cm (4-8″) at resort level, the latest is a month which began with big snowfalls too.
It's all very different to the start of last season when ski areas struggled for cover below 1,800m altitude. It also comes after a warmest and dry first half of autumn/fall.
