Mount Agung could erupt in a “matter of hours” has prompted mass evacuations amid local fears of the potential devastation of the Bali Volcano.
The Indonesian Center for Volcanology and Geological Hazard Mitigation (CVGHM) has raised the Bali volcano alert to 4, meaning an eruption can be expected at any time.
Balinese locals continue to flee the danger zone, which stretches 7.5 miles around Mount Agung.
Terrifying video footage of the Bali volcano shows the mountain spewing tonnes of ashes and smoke as locals brace themselves for its eruption.
A 200m-tall column of smoke was spotted rising from Mount Agung early on Sunday, according to Gede Suantika, the chief geologist monitor the site.
He said: “We observed sulphuric smoke spewing from its carter and we never saw this before.”
More than 1,000 tremors were recorded on the Bali Volcano on Monday and Tuesday, including a magnitude 4.2 quake at 11am BST on September 26.
After the quake, the European-Mediterranean Seismological Center tweeted: “Strongest quake so far while the volcano may be about to erupt.
“Agung volcano is said to be close to erupting and the Bali island just taken by a M4.2 earthquake.”
More frequent shallow earthquakes could be a sign a new batch of magma has moved just under the summit of the Bali volcano, according to Volcano Discovery.
Devy Kamil Syahbana, a seismologist from Indonesia’s volcanology centre, said he’d never seen such high seismic energy on Mount Agung.
He said: “We need to pay attention because these kinds of earthquakes indicate the movement of magma and increase the probability of an eruption.”
The latest Foreign Office advice to Britons planning to visit the region warned “an eruption is possible in the next 24 hours”.
The Foreign Office said: “You should follow the advice of the local authorities and stay outside the exclusion zone. If there is an eruption, volcanic ash clouds could cause flight disruptions.
“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.
