Following the eruption of the Anak Krakatau Volcano in Indonesia, volcanic ash reached a height of 50,000 feet, disrupting more than 300 flights at the airport in Jakarta.

Flights and Airport Impacted

Soekarno-Hatta International Airport in Jakarta suspended flight operations until 1:30 PM local time due to the volcanic ash hazard.

As a result of this disruption, a total of 301 flights, including 58 international services, were affected, and some airlines cancelled or rescheduled their services.

Schools Closed and Precautions Taken

Following students and local residents experiencing eye irritation, authorities decided to cancel educational activities in some schools.

The disaster management agency BNPB announced that weather modification operations, including cloud seeding, are planned to help clear the volcanic ash.

Warnings Issued for the Public

While fishermen in the region cancelled plans to go out to sea for safety reasons, citizens were urged to be cautious.

BNPB issued official warnings to the public to remain calm, limit their outdoor activities, and wear masks.

Situation at Other Volcanoes

The alert level for the Anak Krakatau Volcano, which has been active since Friday, continues to be maintained at level 3.

Additionally, four other volcanoes in the country—Semeru, Merapi, Lewotobi Laki-laki, and Sinabung—are also at a level 3 alert status.
