Soekarno-Hatta Airport Remains Grounded as Anak Krakatau Eruption Blankets Skies in Volcanic Ash
Soekarno-Hatta International Airport remains under temporary closure following an eruption from Gunung Anak Krakatau. According to reports from Kompas.tv, the shutdown—initially ordered from 01.30 WIB to 09.30 WIB—has thrown national and international transit into immediate disarray, forcing the cancellation of 209 flights, including 39 international routes, 160 domestic services, and 10 dedicated cargo operations.
The Scale of the Aviation Paralysis
Volcanic ash poses a threat to modern jet engines. In response to the shifting plume, the Indonesian National Disaster Management Agency (BNPB) confirmed that four regional airports have been shuttered temporarily to protect aircraft from abrasive airborne debris. National police forces, acting under direct orders from the Indonesian National Police (Polri), have mobilized emergency response units.
Geological Volatility Along the Sunda Strait
To understand the gravity of the current closure, one must look back at the restless mechanics of the Sunda Strait. Dr. Mirzam Abdurrahman, a lecturer in the Geological Engineering Study Program at ITB, noted in published academic assessments that maritime volcanoes like Anak Krakatau carry an elevated risk of sudden, high-impact events due to submarine flank collapses and explosive pyroclastic surges.

The December 2018 eruption and subsequent tsunami demonstrated how quickly Anak Krakatau can shed mass—losing more than 50% of its mass during a single catastrophic collapse—without traditional seismic precursor warnings. While current monitoring systems track magma movement and micro-seismicity, sudden destabilization events remind disaster planners of the narrow margins separating routine volcanic monitoring from regional infrastructure crises.
Emergency Protocols and Regional Governance
Beyond the tarmac, local governments are implementing emergency mitigation strategies. According to reporting from Kompas.com, regional heads now hold direct authority to establish mandatory Work From Home (WFH) percentages for civil servants operating in disaster-impacted zones.

Following the eruption, Polri units reinforced their disaster-response readiness, coordinating directly with local disaster agencies to secure coastal communities lining the Anyer beachfront and surrounding districts.
Navigating the Aftermath
With Anak Krakatau showing intermittent activity, aviation authorities maintain a cautious posture, prioritizing passenger safety over schedule punctuality.
