The latest images, taken from the nearby Raman village in Karo, North Sumatra, come as officials raise its volcanic alert to the highest level possible – meaning an eruption is possible within 24 hours.
Huge clouds of ash and steam were seen billowing from Sinabung for miles around yesterday, prompting fears the stratovolcano could be ready to explode.
People living in the area have been warned to stay at least 7km away from the volcano, which killed 10 people when it erupted earlier this year.
And on the nearby tourist hotspot of Bali, experts have warned the island’s massive Mount Agung could blow at any minute.
Some 140,000 people were evacuated from the area around Agung, which is on the same alert level as Sinabung, earlier this week.

Hundreds of earthquakes have been recorded around the 3,000m tall volcano in recent days.
MAGMA Indonesia says this could be due to molten rock flowing close to the surface.
Volcanologist Dr Janine Kripper said the seismic activity around the volcano “was not slowing down” and the “potential for an eruption is still high”.
But Bali’s Governor has insisted the island is still perfectly safe for tourists, and only 28 villages in the danger zone around the volcano would be impacted in the event of an eruption.
He said: “The population of those villages is about 70,000.
“All of these people have already evacuated so the place is empty.
“If something happened, even if an eruption happened today, I guarantee there will be no victims.”
Mount Angung’s last eruption in 1963 killed more than 1,000 people.
The Foreign Office has advised tourists in or about to travel to Bali monitor local media for updates and stay out of the 12km exclusion zone.
Its official guidance says: “If there is an eruption, volcanic ash clouds could result in airport closures and flight disruption in the region.
“In the event of volcanic ash clouds you should confirm your travel arrangements directly with your airline or travel agent before travelling to the airport.”
Around 330,000 British tourists travel to Indonesia each year, with two thirds of them visiting Bali.
