Indonesia raised its warning for Bali's Mount Agung volcano to the highest alert level Monday, closed the island's airport and told residents around the mountain to evacuate immediately, warning of an "imminent" risk of a larger eruption.
Bali's airport was closed for 24 hours from Monday morning, disrupting 445 flights and some 59,000 passengers, due to the eruption and the presence of volcanic ash from Agung, but local officials said the closure could be extended.
Video footage shared by the disaster agency showed cold lava flows known as "lahar" at a number of locations on the mountainside. Lahar carrying mud and large boulders can destroy houses, bridges and roads.
