As seismic activity at Bali’s Mount Agung continues to increase, Indonesian authorities and volcanologists suspect the volcano could erupt at any moment.

More than 100,000 people have evacuated the area, which has been shaken by as many as 175 tremors in a six-hour period, according to the Express. A plume of steam now fills the sky around the Bali volcano.

With a volcanic eruption almost certain (the volcano alert was rapidly raised to the maximum level last weekend), Indonesian officials have urged visitors and villagers to flee the 7.5-mile exclusion zone.

People beyond the designated Bali evacuation zone are also retreating, including many tourists, according to CNN.

Nonetheless, travelers should still consider Bali a relatively safe destination. Sutopo Purwo Nugroho, the Indonesian National Disaster Management Agency’ head of information and data, told CNN: “Most of the [tourist] destinations in Bali are safe from the eruption or dangerous impact of the eruption.”

Mount Agung is northeast of popular tourist destinations Kuta, Seminyak, Ubud, and Denpasar, where the major airport is located.

At this time, no flights have been canceled — but travelers should expect Bali International Airport to close in the event of an eruption.

There is already a comprehensive plan in place to divert flights to 10 other airports across Indonesia, should ash and volcanic gases interrupt scheduled flight plans.
