The Civil Aviation Authority of the Philippines temporarily suspended operations at General Santos International Airport on 8 June after a powerful earthquake struck southern Mindanao, with flights halted while safety checks were carried out. The airport was placed under a notice to airmen from 8:45 a.m. to 3:00 p.m. local time.
CAAP said the suspension was intended to protect the safety and integrity of airport facilities and equipment and to allow inspections of air navigation systems and operational capability. The closure affected domestic services, including Philippine Airlines flights PR453 from Manila to General Santos and PR454 in the opposite direction, as well as services operated by Cebu Pacific and PAL Express.
Initial reports gave the quake a magnitude of 7.0 in Sarangani, before PHIVOLCS revised it to 7.8 and issued a tsunami warning. The temporary shutdown disrupted traffic at the airport serving General Santos City, with passengers advised to coordinate directly with their airlines for rebooking and rescheduling.
