Bali has been gripped by the threat of an imminent volcano eruption for more than two weeks.
The volcano alert has been at the highest level, category four, since September 22.
Over 140,000 people were evacuated from the exclusion zone surrounding Mount Agung.
Half have been ordered to return, though the volcano’s seismic activity remains high.
Indonesia has extended the state of emergency in Bali to October 16.
If Mount Agung does erupt, it’s likely Bali’s Denpasar Airport will be forced to temporarily close, due to the ash cloud hazard in the skies.
Britons in Bali have been urged to heed the advice of the local authorities and stay out of the volcano’s exclusion zone.
The UK Government’s travel advice website said: “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.”
