Security Message for U.S. Citizens: Mt. Agung at Highest Alert

Update:  The U.S. Consulate General in Surabaya alerts U.S. citizens that Mt. Agung, an active volcano in East Bali, is at its highest alert level, and continues to show increased volcanic activity.  On September 22, the Indonesian Center for Volcanology and Geological Hazard Mitigation (CVGHM) raised the volcano’s alert level from Level 3 to Level 4.  Seismic monitoring and analysis by CVGHM indicates a possible, imminent eruption; however, the certainty of an eruption or its exact timing and duration cannot be established.

Restrictions:  Local authorities have restricted access to the mountain within a 7.5 mile (12 kilometer) radius of the summit and have evacuated residents.  Hiking and trekking on the mountain is strictly prohibited.  U.S. citizens are advised to avoid travel to the area around Mt. Agung and monitor local media for updates.  The peak of Mt. Agung is approximately 36 miles (58 kilometers) straight-line distance from Ngurah Rai Airport and popular tourist destinations of Kuta and Seminyak.

Status:  Information on the volcano’s latest status can be found on the following websites:, and  The airport in Bali currently remains open, but travelers should continue to check the airport’s status at:

Impact:  Hazards from an eruption could include falling ash over a wide area.  The danger areas surrounding Mt. Agung could potentially experience pyroclastic flows, lava flows, and volcanic mudflows.  Ash emissions or a large eruption could also impact air travel in the region.

If you are in an area directly affected by the volcanic eruption:

  • Follow evacuation orders issued by authorities, and evacuate immediately from the volcano area.
  • If you are unable to evacuate, to protect yourself from falling ash, you should remain indoors with doors, windows, and ventilation closed until the ash settles.
  • Use a dust mask or hold a damp cloth over your face to help with breathing.
  • Stay away from areas downwind from the volcano to avoid volcanic ash.
