Mount Agung is coughing up a thick cloud of volcanic ash into the sky, forcing mass evacuations of local residents and leading to flight cancellations.
The volatile volcano on the northeastern tip of the island, unexpectedly began erupting on Saturday and there are fears that a more violent eruption is imminent.
Officials are growing fearful that the towering stratovolcano could be about to spew lava in its first major magmatic eruption in 54 years.
The live stream below shows Mount Agung from a CCTV webcam located in Buki Asah in the Karangasem district of Bali.
Alongside the webcam, you can watch a live feed of Magma Indonesia’s seismogram which tracking seismic activity at the Bali volcano.
Any large blue plots on the seismogram indicate when a tremor has occurred, with wider plots representing more powerful quakes.
Each horizontal line on the graph equates to 30 minutes in real time. Watch the video below to find out how to read the seismogram.
Sutopo Purwo Nugroho, of Indonesia’s National Disaster Management Agency (BNPB), reported that an earthquake hit the tourist hotspot on Wednesday.
He tweeted that a 3.1 magnitude earthquake had been felt in Karangasem and reiterated calls for people to evacuate from the danger zone in a calm and orderly manner.
The authorities have called for the evacuation of about 100,00 people from within an up to 10km radius of the volcano. But only about 43,000 have evacuated so far.
When Agung last erupted in 1963, it destroyed several villages on its slopes and killed more than 1,100 people.
At least 22 two villages could be in the destructive path of a volcanic eruption, according to BNPB estimates.
The BNPB said: “Plumes of smoke are occasionally accompanied by explosive eruptions and the sound of weak blasts that can be heard up to 12km (7 miles) from the peak.
“The potential for a larger eruption is imminent.”
Agung volcano has been erupting since Saturday, but it first rose from its deep slumber in September.
The threat of eruption has now grown significantly and officials have raised the threat level to four – the highest possible level.
A red aviation notice grounded all flights to and from Bali at the start of the week. But the warning level has now been downgraded to orange and several carriers are slowly resuming operations.
Air traffic control provider AirNav said in a statement today: “Bali’s international airport started operating normally.”
Bali’s International Airport in Denpasar is roughly 60km south of the volcano, but hazardous volcanic ash poses a severe risk to aircraft engines.
Dr Helen Thomas, from Bristol University’s School of Earth Sciences, told Express.co.uk, that aircraft are also at risk of toxic sulphur dioxide emissions from the volcano.
Another safety risk comes from rapid mudflows, known as lahars or cold lava, streaming down the slopes of Mount Agung.
These dangerous flows are a wet concrete-like mixture of water, rocks and volcanic debris trailing down the mountain.
